Candente Gold Secures Cornerstone for New Growth Strategy - Seite 2

The El Dorado vein system has a history of small-scale mining from two veins. Mining in the area has been documented during the periods of: 1900 to 1927; 1965 to 1975; 1975 to 1983; and 1985 to 1990, often producing direct-to-smelter grade material.   Most recently, from 1985 to 1990, material from three levels to a depth of 30 meters (“m”) below the surface was shipped to the "El Venado" processing plant located near Ruiz, Nayarit, for toll treatment to produce a flotation concentrate. Historical metallurgical balance sheets from this plant indicate the grade of the material was in the order of 5 grams per tonne (“g/t”) gold and 70 g/t silver.

Prospero Silver Corp. explored the El Dorado property between 2010 and 2011, through a series of comprehensive exploration programs which included historical data reviews, geological mapping, geochemical sampling, trenching and drilling. A total of 4,950 m were drilled in 28 diamond core holes to an average depth of 150 m, over a strike length of 440 m. The drilling intersected multiple steeply-dipping silicified mineralized zones extending from near-surface to the 150 metre drilled depth.

Significant results reported by Prospero on Dec 10, 2010
(https://pr.globenewswire.com/FileDownloader/DownloadFile?source=ml&amp ...) included 16.17 meters grading 4.03 g/t gold, 204 g/t silver, 4.0% lead, and 1.75% zinc; and 2.32 meters grading 6.04 g/t gold and 140 g/t silver. The range of widths and grades of the holes within the central portion of the Hundido historical mine area were reported to range from 1.45 meters to 11.22 meters (true widths). The Company’s Qualified Persons have not verified Prospero’s drilling results as due to COVID travel restrictions, they have not yet been able to examine the drill core nor assay data and are therefore relying on data provided in News Releases filed on Sedar by Prospero in 2010 and 2011 and verified by their Qualified Persons.

Prospero also reported that the mineralized zone is 400 meters long and extends up to 180 meters at depth.   Within the mineralized zone Prospero intersected grades ranging from 3.0 to 40.0 g/t Au and 57 to 500 g/t Ag over true widths that range from 0.52 meters to 11.2 meters.  

To the Company’s knowledge, a NI 43-101 compliant mineral resource estimate has not been completed for the El Dorado property, however in July 2011, Prospero conducted an in-house historical resource estimate based on their drilling described above as well as a review of summary cross sections, limited production documentation and other mine records, as well as results from samples of mine dumps, underground sampling (46 by Fresnillo) and 283 surface outcrop samples collected by both Prospero and previous explorers and exploiters.
