Dann eben Silber!
Okay... Gold ist auch dabei. Oder könnte dabei sein.
Den Threadtitel habe ich in Anlehnung an Cross River erstellt.
In die beiden Werte bin ich etwa zeitgleich Anfang des Jahres eingestiegen.
Da es bei meinem Goldexplorer momentan in die Tiefe geht und das nicht nur auf Edelmetallsuche sondern auch mit dem Kurs... eben Silber.

Nach tänzeln im 10er Bereich hat es heute ordentlich geknallt.

Der Wert wurde drüben in Foren diskutiert. Eingestiegen bin ich nach dieser Meldung:

Das klingt irgendwie gut die ...

Ich bin jetzt auch mit von der Partie...
Normalerweise erwarte ich bei solchen Werten einen geradezu signifikanten Anstieg um mehrere 1000 % pro Tag bei der Aktie schon bald.
Bin mal gespannt was da noch so kommt an News.
Diese erbohrten Werte scheinen wohl den Gesamtmarkt ziemlich in Stimmung zu versetzen.
Ich glaube ich schichte mirt mal mein Depot etwas um

Hab mir mal 2500 Stk gekauft heute.

Ich denke das könnte wirklich was werden, die Werte scheinen wohl zu den Größten bisher entdeckten zu gehören.
der abgebildete Bohrkern scheint jedenfalls wohl platinähnlich zu sein, wenn ich das richtig sehe.
Ist das so, Was seht Ihr in dem Bohrkern.
Für mich sieht das eindeutig nach Platin aus.
Ist das so?

Grüß dich,
aber nicht übertreiben mit dem Umschichten,

hier spielt eine große Rolle, dass Silber gerade im Trend liegt und einen gewisser Hype entfacht wurde.
Ist der weg, bleiben dann nur Resultate, Proben, Liegenschaften...

Die sehen erstmal net schlecht aus.

Platin? Wäre mir neu. Hast du denn ein Foto gesehen?

Eher Gold/Silber >>>AU/AG sind angegeben, also auch nicht schlecht.

Antwort auf Beitrag Nr.: 67.402.793 von strabo am 10.03.21 18:40:34

Ja. Ein Bild von dem Bohrkern habe ich mal gesehen ? Wieso fragst Du?

Ist auf jeden Fall demnächst bei 4-5 Euro die Aktie.
Das ist so sicher wie das Amen in der Kirche.
Weißt Du wie groß die Ressourcenschätzung sind? Laut meinen Berechnungen sind das 12 bis 14 Mio. Platin Barren, die da gehoben werden könnten?
Bei einem Aktuellen Preis von 2500 Euro pro Unze x 9 (=1 Platin-Barren = 14500 Euro entspräche das 12.000.000 (kg fürs Platin beim Verkauf) x 14500 Euro ) sind das dann wohl 145 Bil. Euro an Ressource , die die da fördern könnten, wenn es sich um Platin handelt.

Na ja, soll jeder selbst rechnen.

Bei 40 Euro pro Aktie verkaufe ich dann meine die Hälfte von meinen heute Nachmittag gekauften 2500 Stk. bei 21 CAN-Cent!
Ich schätze mal so in einem Jahr ist das.

Und von dem Gewinn Bastel ich mir dann eine Wuppertaler-Schwebebahn-Waggon mit Elefanten drauf

6 HISTORY
6.1 ADDITIONAL HISTORIC RESOURCE ESTIMATES
Marc Jutras, Ginto Consulting Inc, has reviewed and approved the use of this section in the report.
The following discussion of historic tonnages and grades extracted from the mine has not been independently verified and is not considered a current assessment of Mineral Resource grade or expected tonnage, and has been included to provide an accurate property history.
A QUALIFIED PERSON HAS NOT DONE SUFFICIENT WORK TO CLASSIFY THE HISTORICAL ESTIMATES DISCLOSED IN THIS ITEM 6 AS CURRENT MINERAL RESOURCES OR MINERAL RESERVES; AND (II) THE ISSUER IS NOT TREATING ANY HISTORICAL ESTIMATE DISCLOSED IN THIS ITEM 6 AS CURRENT MINERAL RESOURCES OR MINERAL RESERVES.
The Santa María project, historically known as La Unión Mine, dates to 1658. The earliest known operator of this property is the Minas De Iguala Company who operated the property in the 1940’s. Minas De Iguala constructed the existing shafts and on vein drifts and is thought to have been the mine’s most significant producer, extracting exclusively oxide ores. Production data from this period is not available.
In the 1980’s the property was leased to Victor Arias who reportedly exploited approximately 20,000 tonnes of near surface oxide material at an estimated grade of 2 Au g/t and 200 Ag g/t.
The property was subsequently leased to Gustavo Durán, Mining Engineer from 2009 to 2011, during which time a ramp was completed to virgin material below the 50 meter Level. Although Gustavo Durán completed the ramp, for unknown reasons his lease was terminated before completing any substantial stope development. From 2009 to 2011 it is estimated Gustavo Durán extracted 40,000 tons of residuals and backfill waste left by historic operators, at an estimated grade of 1-1.15 Au g/t and 150-200 Ag g/t. The material was processed exclusively by cyanidation.
The Project was inactive from 2011 until the involvement of Minera Cordilleras in 2014.
In February - March 2016, September - October 2016, and June 2017, Minera Cordilleras conducted small- scale selective non-mechanized trial mining and milling totaling 7,098 tonnes grading 337 Ag g/t and
0.78 Au g/t. The trial mining was completed by local contract miners using mining equipment owned by Golden Minerals. The material mined was a mixture of oxide and sulfide mineral types. Recoveries of 73% and 50% for Ag and Au were achieved. Concentrates were sold as a combined bulk Ag/Au concentrate. Results from trial mining and milling have been used to inform this study, but grades and recoveries are not indicative of the Project in general.
6.2 PREVIOUS RESOURCE ESTIMATES
Resources were estimated previously by Tetra Tech with an effective date of April 2015 and were updated with an effective date of March 2017 and a updated resource report September 2018. The Resources shown are considered historic. Cutoff grade assumptions of previous estimates are also no longer valid due to changes in metal price assumptions and additional information pertaining to cost assumptions and recoveries.

7 GEOLOGIC SETTING AND MINERALIZATION
Marc Jutras, Ginto Consulting Inc, has reviewed and approved the use of this section in the report.
Portions of the following geologic descriptions have been translated and adapted from the 1985 publication by Servicio Geológico Mexicano authored by Chávez Espinoza and Sánchez. The remaining descriptions come from observations made during Minera Cordilleras’ exploration activities.
7.1 REGIONAL GEOLOGY
The Project site is in the Sierra Madre Occidental (SMO) volcanic province and is on the border between the states of Chihuahua and Durango physiographic provinces. The property is situated on the southern extent of the Mesa Central metallogenetic province which includes the Parral-Santa Bárbara-San Francisco del Oro mining districts.
The SMO province is comprised of two primary sequences of igneous rocks. The upper series (UVS) is dominated by calc-alkaline volcanic rocks with associated rhyolitic intrusions and ignimbrites. The lower series (LVS) contains abundant andesites. Large sinters were formed from the recirculation of meteoric waters heated by the thick volcanic sequence often associated with basaltic lava flows. In addition, there are large stretches of acidic volcanic domes of Miocene to Upper Eocene age.
The eastern and central portions of the SMO province are characterized by sedimentary rocks of marine origin, including calcareous shales and limestones. The limestone layers are thinly bedded, fine-grained and light to dark. The limestones are often folded and intruded by felsic plutons. Folding occurs on a scale of up to regional folds greater than 500 m. The limestones are middle to upper Cretaceous in age.
7.2 LOCAL GEOLOGY
The local geologic setting is represented by rocks of the Parral Formation, which consist of sedimentary rocks, shales and limestones of the Grupo Mezcalera of Lower Cretaceous age which were covered by Eocene volcanic rocks and intruded by porphyry monzonite and granodiorite stocks and dikes. The pre-existing rocks were structurally arranged by regional scale extensional block faulting and folding by Oligocene volcanic events with intrusions of hypabyssal origin including mineralizing fluids that were emplaced in the region. Tertiary granodioritic and monzonitic intrusive bodies and dikes affected locally the Parral Formation rocks causing metamorphic skarns and hornfels with associated mineralization. The local geology is depicted in Figure 7-1, and has been adapted by GSM Map G13-A57.
Mineral Resources Engineering 7-2
Figure 7-1: Local Geology Map
7.3 PROPERTY GEOLOGY
The geology of the property is dominated by rocks of the Parral Formation, rhyolites, granodioritic intrusive and a post-mineral basaltic cap on the eastern edge. The Santa María mineral deposits are hosted in and adjacent to a rhyolitic dike and granodioritic rocks. Veins are observed hosted by skarns and silicified limestones of the Parral Formation and the Tertiary rhyolite dike. The property geology is depicted in Figure 7-2.
Mineral Resources Engineering 7-3
Figure 7-2: Property Geology Map
7.4 PROPERTY MINERALIZATION
7.4.1 SANTA MARÍA MAIN VEIN
The primary Santa María vein gently curves following the contact of the associated rhyolite dike and can be traced on surface for 1,150 m. The current demonstrated down dip extent is 260 m and remains open at depth and along strike.
The vein occupies a fault zone near the contact between the Parral Formation sediments and the Tertiary dike. Breccia textures healed by quartz gangue are common in the vein. The vein varies in width between 1 and 4 meters with an average width of 2 meters. The dip of the vein is north varying between 75 and 85 degrees. In the underground workings, occasional post mineral normal faults can be observed to offset the mineralization locally. Drill holes SM 18-03 and SM 17-04 appear to have intercepted a mineralized bulk zone with higher grades.
Mineral Resources Engineering 7-4
At surface the vein is oxidized, and oxidation extends irregularly to ~75 meters depth. In the easternmost portion of the vein sulfide mineralization is preserved in the footwall of a cross-cutting fault. Oxide portions of the vein are characterized by strong iron oxides including goethite and hematite. The observed sulfide minerals are galena and sphalerite with rare occurrences of acanthite and ruby silver sulfosalts.
7.4.2 SANTA MARÍA DOS VEIN
The Santa María Dos vein is a hanging wall splay from the Santa María Main vein. It diverges from the Main vein close to the entrance of the Santa María decline and can be traced along surface for 1,050 m. The vein has been drilled down-dip for approximately 200 m where it intersects the Main Vein. The Santa María vein is open along strike to the east.
The vein appears to occupy a fault zone near the contact between Parral Formation limestones and an east-west striking diorite dike. The vein varies in width from 0.25 to 3.5 m and average width is around 1 m. The vein dips to the south varying between 65 and 85 degrees.
At surface the vein appears as a narrow, oxidized banded and brecciated quartz vein. Oxidation is variable. In the west it extends to 40 m depth, and in the east up to 150 m depth. Oxide parts of the vein are characterized by iron oxides including goethite and hematite, and in the sulfides zone of the vein sulfide minerals are dominated by pyrite with minor galena and sphalerite.

Mineral Resources Engineering 7-5
7.4.3 NORTH VEIN
The North vein crops out approximately 350 m north of the Main vein and can be traced along surface for 350 m. The western extension is covered by post-mineral basalts. The vein varies in width from 0.15 to
2.2 m with an average of 0.8 m. The vein has been explored by several small prospect pits.
The vein has a northeast strike and is steeply dipping (80o to the NW or SE depending on the vein limb). The vein appears to be offset by a NW striking fault. The host rocks are the Parral Formation limestones.
At surface the vein is a narrow oxidized banded and brecciaed quartz vein with variable oxidation and rare pyrite.
A total of 38 chip-channel samples were collected from the North Vein.
Sampling returned grades up to 3.01 g/t Au, 196 g/t Ag, 0.41% Pb and 1.09% Zn.
7.4.4 CERVANTES VEIN
The Cervantes vein crops out 450 m to the east of the Santa María vein system and has been mapped and sampled over a 900 m strike length.
The vein varies in width from 0.25 to 1.3 m with an average of 0.6m. The vein is explored by several prospect pits and shafts and in the center of the system, and an 80 m long tunnel has been developed on the vein exploring an area where sulfide mineralization occurs.
The vein has a north-south strike and dips steeply (80o) to the west within a narrow fault zone within the Parral Formation limestones. On the surface the vein is a narrow banded and brecciated quartz-calcite vein and with variable oxidation. Adjacent to the small mine, the vein has a northeast strike and is steeply dipping (80o to the NW or SE depending on the vein limb). The vein appears to be offset by a NW striking fault. The host rocks are the Parral Formation limestones. The vein contains moderate iron oxides and iron oxide staining. However, the vein cropping out above the small mine working contains significant sulfides including sphalerite, galena and pyrite. A total of 27 chip-channel samples were collected from the Cervantes Vein.

8 DEPOSIT TYPES
Marc Jutras, Ginto Consulting Inc, has reviewed and approved the use of this section in the report.
The Santa María deposit type can be described as an epithermal quartz - calcite vein system. Typical banded epithermal textures are observed in underground workings and drill core. Brecciated mineral textures filled by quartz and calcite are common. Low concentrations of galena and sphalerite and the presence of silver minerals indicate an elevated level of exposure within the epithermal system. Figure 8-1 shows typical epithermal mineralized textures encountered at Santa María in drill core specimens.
It is common for epithermal deposits to have higher-grade lineation trends internal to the structure’s plane often related to regional structures or preferential host lithologies. Drilling, sampling, and modeling of results indicate that mineralized shoots within the structures have high angle rakes. Modeling has defined two such shoots.
Exploration programs have been planned in the context of mineralized structures, assuming the Santa María and Santa María Dos deposits are approximately planar and follow the general structural trends observed on the surface and throughout the underground workings. Successful exploration drilling down- dip of the workings supports the assumption that the mineralized structures follow oriented structural trends.

9 EXPLORATION
Marc Jutras, Ginto Consulting Inc, has reviewed and approved the use of this section in the report.
Exploration by Minera Cordilleras consists of surface and underground geologic drilling, mapping and channel sampling. No known geophysical surveys have been completed to date. Historic exploration by previous operators, except for on mineralized structure drifting, is not known. The Chihuahua regional office of the Servicio Geológico Mexicano (SGM) generated a property report in 1985 which describes generalities of the geology and references the collection of confirmatory channel sampling.
Locations for the collection of channel samples were chosen by the Project geologist during mapping. Underground channel samples are located within existing deposit drifts. Channels were marked on the structure by the geologist and collected as close to perpendicular to strike as feasible during sampling. Using a rock hammer, five-pound sledge hammer and chisel, samples weighing at least 2 kg were collected in a bucket and then transferred to a transparent plastic bag labeled with a sample number. For samples located on the drift back, the sampler stood on a ladder and a tarp was placed under the sample area to catch the sample chips. The material on the tarp was then funneled into the sample bucket and again transferred to a labeled plastic bag. Both the bucket and tarp were cleaned between each sample collection. Coordinates of underground sample locations were initially tape surveyed by a geologist using a sighting compass and were corrected to align with the survey of the drift when completed by transit survey. Each sample location was not independently surveyed.
A total of 2,286 underground channel samples were collected for analysis and are included in the Santa María database. Channels were taken within existing development that spans approximately 575 m east to west and 110 m down dip. Samples were spaced between 5-15 meters, with few spaced more than 25 meters apart due to access for exploring the vein strike but spaced 1-4 meters apart in areas that were potentially prospective for mining. A summary of the significant high-grade channel samples is shown below in Table 9-1.
Significant channel sample results indicate the deposits host higher grade areas preferential to metal deposition and these areas can be observed throughout levels as mineral shoot domains. The results also demonstrate in some areas sampling “nugget effect” is significant, meaning erratic high or low-grade values can be observed inside or outside of generalized shoot trends.

The sampling of the mineralization was mainly carried out on sample lengths varying from 0.5m to 1.0m across the orebody from channel sampling and at various angles from surface and underground drilling. Channel samples were taken on tightly spaced interval sets along underground exploration drifts. Underground drilling was carried out as fans providing good local coverage, while surface drilling was carried out on a wider spacing. The quality of the sampling is believed to be of sufficient quality.

10 DRILLING
Marc Jutras, Ginto Consulting Inc, has reviewed and approved the use of this section in the report.
The Project database contains 59 surface and underground drill holes, totaling 9,922.61 m, drilled during four campaigns in 2014, 2016, 2017, and 2018 by Minera Cordilleras. Surface drill holes are NQ size with either plastic or steel surface casing. Drilling was completed by Maza Diamond Drilling S.A. de C.V. of Sinaloa, Mexico utilizing a portable rig with a 500 m maximum depth.
In 2016 Minera Cordilleras completed 24 drill holes from underground using Boart Longyear LM30 and LM75 drill rigs, totaling 2,190.1 m. The purpose of the underground drilling was primarily to delineate the mineralized shoots and increase Resource classification. Two of the holes (SM16-18 and SM16-19) targeted the vein east of the known strike extension at the time and intersected significant high-grade mineralization.
In 2014 Minera Cordilleras completed 13 drill holes with total drilled depth of 2,884.50 m, and in 2017 Minera Cordilleras completed 14 drill holes with total drilled depth of 3,305.90 m; while in 2018 a total of 8 drill holes were completed with total depth of 1,542 m.
Surface drill hole collar locations were surveyed by handheld GPS and then by a professional surveyor with the aid of a Differential GPS. Underground drill collars were surveyed using a Total Station. Drill hole orientations were established by measurements of casing using a field compass and then down hole surveyed using a magnetic Reflex instrument.
Table 10-1 shows the locations and orientations of the drill holes relative to the surface topography and underground development. Drill hole orientations have been inclined to target the vein as perpendicular to strike and dip as practically possible given the surface terrain and access.

Figure 10-1: Drill Hole Location Map
The majority of the samples from channels, surface and underground drill holes was carried out on 0.5m to 1.0m intervals, which provides sufficient discretization of the mineralized veins. The underground channel samples from the on-vein drifting provide good confirmation of the veins’ true thicknesses, orientations, and local geometric configurations.
From the QA/QC programs related to the assayed samples (Section 11.4), there is no known bias observed from these results.

11 SAMPLE PREPARATION, ANALYSIS AND SECURITY
Marc Jutras, Ginto Consulting Inc, has reviewed and approved the use of this section in the report.
Data summarized in this section and utilized for estimation of Resources has been collected by Minera Cordilleras staff. The sample preparation, analyses and security procedures implemented by Minera Cordilleras meet standard practices. The data collected is of adequate quality and reliability to support the estimation of Mineral Resources. Only Project level staff are involved with the selection, preparation and delivery of samples to the laboratory.
Historic sampling by previous operators is not considered current and has therefore not been described in this section. The Project database contains results collected from both drill core and channel sampling.
11.1 SAMPLE PREPARATION
In this section drill core and channel sampling are discussed.
11.1.1 DRILL CORE
Diamond drill core is transported from the rig to the core preparation site, located at the mine entrance, by truck. Following geotechnical logging by field assistants, geologists log the core and select sample intervals. Sample intervals are selected only where the geologist anticipates mineralization to exist. In practice the core is extensively sampled in both the hanging wall and footwall about the primary deposit intervals but is not sampled continuously from top to bottom. Drill core that is selectively un-sampled can be considered waste; however, no numeric value or null place holder is inserted into the Project database. Sample selection begins and terminates at alteration or lithologic contacts, constrained to a minimum length of 20 cm and maximum of 1.5 m. During the process of sample selection, the geologist draws a centerline to guide the core cutters. The center line is rotated by the geologist to align with the apex of observable vein structures to minimize sample selection bias.
A sample sheet is provided to the core cutters containing sample numbers and from, to intervals. In addition to a cut sheet the sample number and meters are annotated on the white plastic core box using a marker, Figure 11-1. Sample numbering begins where the previous sample batch left off. The core cutters have been instructed to cut the core down the marked centerline using an electric powered wet diamond saw, and to always place the right-hand portion of the cut core in the sample bag. Sections of broken core or low recovery are carefully divided to reduce bias; however, these sections are inherently less reliable than sections of competent core. The core cutters write the sample number using a marker on a transparent plastic bag and tie off the bag using twine when complete. A tear-away sample tag system has not been implemented but is recommend in the future. Five samples are grouped and placed in a large rice sack. The beginning and ending number of the five samples contained in the sack is written on the outside of the bag. The sack is tied shut with twine when full.

Figure 11-1: Drill Core Sampling
11.1.2 CHANNELS
The Project database contains only underground channel sampling, and no surface samples have been collected. The geologist first maps the structures and veins underground; following mapping, the geologist uses a can of red spray-paint to mark channel sample lines spaced along the strike of the drift. Channel samples are selected only in mappable mineralized structures and do not include hanging-wall or foot-wall waste samples. Samples are initiated and terminated based on observable vein styles or mineral type difference across the deposit. Sample lengths are dictated by structural thickness with a minimum of 20 cm with no defined maximum, but do not typically exceed 2 m in length.
Field assistants, often with sampling experience at nearby operations, are recruited to assist with channel sample collection. Under the supervision of a geologist, the samplers are instructed to fully chip away the entire painted portion of the channel sample indicated by the geologist. Using a rock hammer, chisel and five-pound sledge hammer, one sampler chips the vein while another sampler holds a bucket to capture the sample, Figure 11-2. The material in the bucket is then poured into a transparent plastic sample bag annotated with the sample number that is painted on the wall by the geologist. The bucket is then tapped out and wiped out by hand. For hard to reach samples, samplers utilize a ladder to access the drift back while a helper positions a tarp on the ground to catch the chiseled material. The tarp is then funneled into the sampling bucket. Both the bucket and tarp are cleaned between the collection of samples. Preparation, analyses, and security of channel and drill hole sampling are the same from placing the material in a transparent plastic bag onward.

11.2 SECURITY
The Project is located well off main roads and is guarded by a caretaker who lives in a mine building near the mine entrance while the site is active. Samples awaiting delivery to the ALS preparation facility in Chihuahua are placed in a locked building overnight. Samples are delivered to ALS Minerals in Chihuahua City, Chihuahua, Mexico (ALS Chihuahua) by Minera Cordilleras staff by road as needed, typically every two weeks.
11.3 ANALYSES
Sample batches are delivered to ALS Chihuahua for preparation and then shipped to Vancouver, British Columbia, Canada (ALS Vancouver) for analysis. The ALS Vancouver laboratory is independent of Golden Minerals and Minera Cordilleras and is ISO 17025-accredited, the accreditation of ALS Vancouver encompasses preparation processes completed at ALS Chihuahua.
Samples are initially analyzed for Au using fire assay with atomic absorption spectroscopy finish (AA24) with rerun for values exceeding 10 g/t Au using fire assay with gravimetric finish (GRA22).
Samples are also initially analyzed for Ag, Pb, Zn, Cu, and 32 additional elements using aqua regia inductively coupled plasma - atomic emission spectroscopy (ICP41) with rerun for values exceeding 100 g/t Ag, and 1% Pb, Zn, Cu analyzed by ore grade aqua regia inductively coupled plasma - atomic emission spectroscopy (OG46).

11.4 QUALITY ASSURANCE AND QUALITY CONTROL FOR SAMPLE ANALYSIS
Minera Cordilleras’ quality assurance (QA) measures involve the use of standard practice procedures for sample collection for both drill core and channel sampling as described above, and include oversight by experienced geologic staff during data collection. Quality control (QC) measures implemented by Minera Cordilleras include in-stream sample submittal of standard reference material, blank material and duplicate sampling.
The insertion of control samples is dictated by the last digit of the sample ID number; the sequence is independent of the drill hole or channel sample set and is continuous through the sampling campaign. For example, the first instance of a drill core sample id ending in “0” is a blank sample and is placed in a sample bag rather than a collected core sample. On the next instance of a “5” the lab is instructed on the sample submittal sheet to create and test a fine duplicate following pulverizing. On the next instance of a “0” the lab is instructed to create a coarse duplicate at the crushing stage. On the next instance of “5” a low grade standard sample is placed in the sample bag instead of a collected sample and the next “0” a high-grade standard. The same order described above was utilized for the channel sampling campaign; however, the submittal was conducted on sample id’s ending in “0” only. The effective QC submittal for the drill core campaign is 1 control sample for 10 collected samples and 1 control sample for 50 for the channel sample campaign.
11.4.1 QUALITY CONTROL SAMPLE PERFORMANCE
QC sample performance was generally tracked throughout the campaign by Minera Cordilleras staff and no key issues were observed, but results suggest standard control sample strategies could be refined. It is recommended that standard reference material with a grade closer to the Resource average for Ag be sourced and tested more frequently to provide a consistent baseline.
As part of this report, QC sample performance was reviewed. Relevant QC sample performance is summarized below. Six standard references were implemented for testing, with the certified values for each shown in Table 11-1 below. Information regarding certified values for one of the low-grade standards was not located but the test results show consistent values. In addition, standard M2-87438 which is above the rerun limit was initially tested twice, but not rerun by the lab due to an insufficient sample following initial testing.

Standard performance was determined through methods suggested by RockLabs of Auckland, New Zealand and provided in a Microsoft Excel™ template on their website for plotting standard performance. The RockLabs analytical spreadsheet defines accuracy as the tested mean (in stream), at the laboratory in question, minus certified mean over the certified mean. Precision is defined as the percentage of standard deviation over the tested mean. For both precision and accuracy, outliers more than three times the tested standard deviation are ignored for performance assessment and identified for review.
When compared to two standard deviations of the assigned values, as commonly but improperly done, the results falsely indicate poor performance; however, using the performance assessment determinations defined by RockLabs, which establishes failure thresholds based on standard deviations calculated from sampling of the laboratory in question, the standards perform well except for ore grade reruns in sample SP-49 which perform poorly for both high-grade gold and low-grade silver. The deficient performance has little bearing because very few samples have grades that trigger the Au rerun. Standard results are shown in Table 11-3. By the above defined limits, an outlier in most cases is considered a batch failure. One outlier has been observed in the review of submitted standards. The failure rate observed is not unusual for a program of this size; however, it is suggested that the failure be investigated further to determine if batch reruns are necessary.

The blank material has been sourced from barren coarse sand. The performance of the blank material shows very few failures. Failures observed (two gold and two silver) are minor and most likely a result of very small amounts of gold and silver in the blank material and low-end instrumentation precision, and not a result of contamination given the grades of the prior samples Figure 11-4 shows blank performance for both gold and silver.
Figure 11-4: Blank Control Analysis
The performance of the fine and coarse duplicates shows good reproducibility. Poor reproducibility in coarse duplicate sample pair sample, 125131 and 125130, for both gold and silver was investigated and determined to be caused by nugget effect.

12 DATA VERIFICATION
Marc Jutras, Ginto Consulting Inc, has reviewed and approved the use of this section in the report.
The quality of data collected by Minera Cordilleras meets industry standard practice and is sufficient to support the estimation of Mineral Resources. The following section describes steps taken by the author of this report to verify data provided by Minera Cordilleras that was used to create the new resource calculated by Marc Jutras in November 2020.
Data verification conducted during the previous site visit included observations of drill hole collar locations and orientations, drill core, channel sample locations, channel sample collection, underground mine accesses, on mineralized structure drifts and stopes, stockpiled oxide material from waste backfill mucking. The deposit was witnessed in underground workings and at the surface but was not traversed in its entirety. Confirmatory sampling of drill core was not completed due to the sparseness of mineral intervals; the author did not want to eliminate the physical record of previously halved core for the purposes of verification.
Drill hole collars and their orientations were observed in the field using a compass and handheld global positioning system (GPS). Verification of collar locations and orientations were found to correspond to those provided by Minera Cordilleras.
Core boxes containing mineralized intervals of the following drill holes SM14-04 and SM14-09 were made available for visual review. The textures observed are typical of epithermal veins including banding of quartz and sulfide minerals, quartz flooding, brecciation and oxidation. In addition to visually reviewing core on site, the author has reviewed core photos of mineral intervals and spot checked the assay database provided with assay certificates from the laboratory.
As part of the data verification, 18 channel samples were selected to be re-sampled and submitted to ALS for analysis. The samples were chosen by the author of this report and were collected on the ramp and the East side of the 1890 m level. The collection of the samples from within the mine was witnessed by the author. The samples were delivered to ALS Chihuahua where the sample preparation facility was toured. The original samples from the Project database are compared to the check samples in Figure 12-1; the chart axes have been log base 10 transformed. The results of the verification sampling correspond well to those provided by Minera Cordilleras
The author, during the site visit and from the date of the site visit to the date of this report, confirmed that no additional work on the property had been done since that work stated in the 2018 Tetra Tech Report. The author has independently reviewed this by, (i) during the site visit reviewing all of the existing workings underground to ensure no further work has been done other than that described in the report; (ii) reviewing all available drill data to ensure no further drilling has been recorded other than that described in the report; (iii) reviewing news releases from Golden Minerals that would have noted Santa Maria work over the last two years; (iv) reviewing SEDAR filings by Golden Minerals for reporting on the Santa Maria over the last two years; and (v) conducting conversations with Golden Mineral’s personnel discussing whether any recent physical work had been done on the property that may effect the validity of the resource model used in the analysis.

In addition to re-sampling of channels, a stock pile of approximately 75 tonnes of historic waste backfill mucked out of the mine by a LHD (Load, Haul, Dump) was tested with five randomly selected samples, shoveled and bagged by the author and submitted to ALS for analysis. The results of the five samples are included in Table 12-1 below. Although the material was sourced from the property, the results are neither representative of the virgin material or the property, nor do they represent expected grades of Resources or potential future mining operations, but they do confirm the presence of mineralized material on the property.

13 MINERAL PROCESSING AND METALLURGICAL TESTING
Samples in the existing underground workings were collected for visual evaluation and metallurgical testing at the Golden Minerals Lab in Valardena, Durango, Mexico. The testing was performed to better understand the cyanidation of the sulphide and transition material, which would enable all the extracted material to be treated in a single processing circuit. The results of the testing were reasonable relative to the past metallurgical testing that is outlined in this section. The inspection of the samples and the results of the testing supported that there are no processing problems or elements that would cause problems with treating the Santa Maria material at the local Toll Mills in the area.
Samples of oxide and sulfide material were subjected to scoping level metallurgical testing at Golden Minerals’ Velardeña Mine laboratory in September 2014. This test work indicated that the oxide material is amenable to direct cyanide leaching. The sulfide material underwent flotation testing to concentrate the precious metals into lead and zinc concentrates. The results of this flotation testing indicate the potential to produce a relatively low-grade lead concentrate with a relatively high silver content, as well as a high-grade zinc concentrate.
Pilot scale flotation process test work was undertaken from September 10 to October 16, 2015 on mixed material. In this test, the aim was to produce a concentrate with high silver content.
Additional samples of the sulfide material were subject to laboratory flotation testing by SGS in October 2016 to evaluate production of a bulk silver-bearing concentrate as opposed to the production of separate lead and zinc concentrates.
Golden Minerals engaged RDi Inc. in January 2017 to perform additional rougher and cleaner flotation test work on the same composite as used in the October 2016 SGS testing. This test work evaluated both the impacts of alternative reagent suites as well as grind sizes.
Golden Minerals expanded the Resource base in 2018. Currently, the oxides constitute 37% of the total Resource and mixed ore and sulfides account for 19% and 44% of the total Resources, respectively.
RDi recently completed additional scoping level metallurgical test work on all three ore types (i.e., oxides mixed and sulfides). It is currently envisioned that all three ore types will undergo toll processing. The oxide ore will by cyanide leached for silver extraction whereas mixed and sulfide material will be floated to produce a saleable concentrate, and the flotation tailings can be cyanide leached for additional silver recovery or sent to the tailings pond. Additional test work would be required to optimize the process parameters and to establish a higher level of confidence regarding anticipated grade and recovery values.
13.1 2014 TESTING PROGRAM
13.1.1 OXIDE MATERIAL TESTING
Preliminary whole ore leach test work on oxide material suggests it is possible to achieve leach recoveries of 80% and 79% for gold and silver respectively within 48 hours. The results of this testing are shown below in Table 13-1.

Details pertaining to reagent consumption, dosage, and particle size were not included in the provided summary of test work. Hence, additional test work was undertaken in 2018 to determine the reagent consumptions for the PEA.
13.1.2 SULFIDE MATERIAL TESTING
Preliminary flotation test work was focused on making marketable lead and zinc concentrates. This test work suggests it is possible to recover the gold and silver into lead and zinc concentrates. The final cleaner concentrate grades produced in this test work are shown below in Table 13-2.

Concentrate market terms have not yet been investigated. Indications from this initial test work are that the lead concentrate contains significant amounts of arsenic and antimony as well as a relatively low lead content, which may adversely affect the commercial terms. The high silver content of the lead concentrate suggests that it could potentially be marketable as a silver bearing bulk concentrate rather than as a traditional lead product.
The test work indicates the zinc product is a relatively high-grade concentrate, and the marketability may not depend on the precious metal content.
No details were provided at the time of writing regarding the specific test work conditions such as reagent dosage, retention time, and grind size.
13.2 2015 MIXED MATERIAL PILOT PROCESSING
Pilot scale tests were performed in the time periods of September to October 2016, February to March 2016, and June of 2017, on mixed material from the Santa María project at the Silveyra Mill in Parral. Over the course of the testing, approximately 7,098 tonnes of material were processed to produce a bulk concentrate for metallurgical and marketing purposes. The silver head grade averaged 337 Ag g/t. Silver recovery averaged 73% at a concentrate grade of 8,897 Ag g/t. Gold head grade averaged 0.78 Au g/t and recovery averaged 50% at a concentrate grade of 14 Au g/t.
Recoveries from the pilot processing from September to October 2016 are shown below on a measurement periods, rather than daily basis, in Figure 13-1.

13.3 2016 SGS TESTING PROGRAM
13.3.1 ROUGHER FLOTATION TESTING
Following the completion of the bulk mixed material pilot production, three sulfide flotation lab-scale trials were performed by SGS in 2016. The first of these trials attempted to suppress pyrite and zinc recovery to the bulk concentrate, while the second trial attempted to maximize gold recovery. In doing so, the latter trial resulted not only in an improvement to gold recovery, but also yielded a better silver grade/recovery curve. These results are shown below in Table 13-3 and Table 13-4 respectively.

The third test evaluated the effect of a specialty collector, known as Max Gold, to supplement the reagents used in the second test. This resulted in further improvement to gold recoveries, while having negligible impact on the resulting concentrate silver grades compared to the second test. This suggests that a sizable portion of the gold in the rougher feed is present in liberated form at a grind size of P80 200 mesh. The results of this testing are shown below in Table 13-5.

13.4.1 SULFIDE MATERIAL ROUGHER FLOTATION TESTING
Testing by RDi in January 2017 evaluated the impact of a longer retention time, reagent selection, and grind size on the rougher flotation response on the same composite, averaging a head grade of approximately 450 g/t Ag, as used in the 2016 SGS test program. The results for the rougher flotation concentrates produced after a 9-minute-long retention time are shown below in Table 13-7.

This test program indicated that there is a benefit to a longer retention time based on the elevated Ag recoveries. Additionally, test FT-1 and FT-2 indicated that the rougher flotation response is similar at 150 mesh to that obtained at the finer grind size of 200 mesh. This has positive implications with respect to the proposed toll mill facility as
Mineral Resources Engineering 13-6
Golden Minerals’ management indicates the facility is at present configured to produce a rougher flotation feed of 150 mesh.
With respect to reagent selection, this testing indicated that the selection used in the SGS test work is likely to produce lower concentrate grades, as exhibited by the higher mass recovery in FT-7, than alternative reagent suites. The elevated recovery results obtained in FT-6 indicated that a combination of PAX and 3477 represented the most favorable selection for increasing Au and Ag recovery, and thus were selected for use in the later cleaner flotation testing. However, as the results obtained with 3477 are still comparable to AP404, both are worthwhile for inclusion in future test work.

...freut sich, die Diamantbohrlöcher 4 und 5 aus dem laufenden 8.000-Meter-Bohrprogramm auf dem Grundstück Santa Maria in Parral (Mexiko) bekannt zu geben.

Peter J. Hawley, CEO und President, bemerkt: "Der Fence der Bohrlöcher 4, 5 und 6 befindet sich etwa 125 Meter östlich des bisherigen Fences der gemeldeten Löcher 1, 2 und 3.

"Wie erwartet beginnen wir bei der Durchquerung in Richtung Osten auf den Rand eines sekundären Nord-Süd-Strukturtrends zu stoßen. Bohrloch SM20-04, das in einem Winkel von -60 Grad gebohrt wurde, durchschnitt 12,5 Meter mit einem Gehalt von 22,37 g/t Ag Eq in -200 Metern Höhe in einer von Norden nach Süden verlaufenden Verwerfung, die die Santa-Maria-Struktur leicht nach Süden verschoben hat. Diese Verschiebung ist auch in der ersten vorrangig von Ost nach West verlaufenden nördlichen IP-Anomalie IPSM-04 deutlich zu erkennen, die denselben Versatz aufweist, auf den wir gestoßen sind.

"Ein weiterer Beweis für den Nord-Süd-Trend findet sich in Bohrloch SM20-05, das nicht nur den Rand der Santa-Maria-Struktur durchteufte, sondern auch drei zusätzliche, von Norden nach Süden verlaufende mineralisierte Strukturen durchteufte, die bis zu 232,08 g/t Ag Eq auf 2,20 Metern, 162,64 g/t Ag Eq auf 0,55 Metern und 1,6 Meter mit 46,62 g/t Ag Eq meldeten, bevor sie auf den Rand der verdrängten Santa-Maria-Struktur bei -300 Metern in der Vertikalen trafen und 53,21 g/t Ag Eq auf 7,2 Metern meldeten.

"Diese Abschnitte untermauern die Theorie, dass die Nord-Süd-Strukturen nicht nur leicht versetzt zu den Ost-West-Strukturen verlaufen, sondern dass sie vor allem mineralisiert sind. Wir erwarten, dass dies im nächsten Bohrloch-Fence weitere 200 Meter weiter östlich und in der Mitte dessen, was als Zentrum der Nord-Süd-Struktur interpretiert wird, die Santa Maria durchschneidet, noch deutlicher zu sehen sein wird.

"Die erneute Protokollierung des zuvor gebohrten Lochs SM-17-10 zeigt, dass es die Nord-Süd-Strukturen zwischen den Löchern SM20-04 und 05 im rechten Winkel zur Struktur und nicht entlang der Struktur durchschnitten hat und 1,40 g/t Au, 862 g/t Ag, 934,02 g/t Ag Eq. ergab.

"Diese Bohrungen plus die Ergebnisse von Bohrung SM20-06, die noch bekannt gegeben werden, ergänzen die Bohrabschnitte und die Interpretation der neu interpretierten Struktur Santa Maria und definieren die Struktur eindeutig von der Oberfläche bis hinunter zu -350 Metern in der Vertikalen, was die tiefste Bohrung ist, die jemals auf dem Grundstück niedergebracht wurde. Die Struktur ist nach wie vor sehr konform und wurde genau dort durchteuft, wo sie vorhergesagt wurde, was ein gutes Zeichen für die Erweiterung von Santa Maria und die Erhöhung der aktuellen NI 43-101-Ressourcen auf dem Grundstück ist, wobei bisher nur 5 Bohrlöcher gebohrt wurden."

Peter Hawley fährt fort: "Die Daten, die aus diesem Fence von Bohrlöchern mit den mineralisierten Nord-Süd-Strukturen, die nun offensichtlich sind, gewonnen werden, sollten nicht nur dazu beitragen, die Gesamtressource um weitere Silberunzen zu erweitern, sondern uns auch ermöglichen, das Verhalten dieses robusten mineralisierten Systems für zukünftige Bohrungen zu interpretieren und zu modellieren, während wir von der aktuellen Ressource nach außen expandieren. Wir haben nun zwei mineralisierte Leitungssystemen, die beginnen, sich zu durchschneiden, was ein gutes Zeichen für zukünftige Bohrungen ist."

Stimmt, ich hätte den unteren Teil vielleicht schwarz markieren können

hatte ich in der Eile aber vergessen.

Puuuh... das war knapp.

[dementia]

Kurs zieht an in freudiger Erwartung von neuen Bohrergebnissen.
Damit wären wir aber nur bei der Hälfte des 9200m Bohrprogramms angelangt.
Also noch viel Luft und Raum für Spekulation bis in den Sommer hinein.

Ebenso muss Fabled noch ein größeres Statement zur Kupferliegenschaft veröffentlichen.
Davon gehe ich jedenfalls aus..

Ja habs gesehen Fabled Copper is jetzt handelbar in Canada zu 0.05 CAD..mc ca 17 mio mit 340 mio shares. Recht interessant

Kein aktueller Kurs seit 28.12.21

Wird Fabled nicht mehr gehandelt, habe ich was verpasst?? 🤔

Was geht da ab? 46% im Plus!!!!

[strabo]

Nix groß geändert. Manchmal kostet es einfach nur Zeit.

Tech-Crash lässt Rohstoffe aufleben, wenn dann ein halb vergessener Werte mit solchen Bohrergebnissen aufwartet kommt dann eins zum anderen.
