Highlights of the Chimo Mine property:

  • The new resource estimate consists of (FIGURE) :

    • 6,616,000 tonnes at an average grade of 3.21 g/t Au for a total of 684,000 ounces of gold in the Indicated category and ;
    • 15,240,000 tonnes at an average grade of 2.77 g/t Au for a total of 1,358,000 ounces of gold in the Inferred category.

The resource estimate is constrained using DSO (“Deswik Stope Optimizer”) with a cut-off grade of 2.0 g/t Au for the North and South Gold Corridors and 1.5 g/t Au for the Central Gold Corridor and using a price of gold of USD 1,612 US / oz.

  • The results of recent work, that add value to the resources, include :

    • The industrial sorting tests of the mineralization allowed to produce a concentrate representing more than 50% of the mass of the original material with a percentage increase of 170% of the gold content compared to the feed of the sorter. The increase in the content of the preconcentrated material, preceding the machining operations, favors:
      • Increase the recovery rate at the mill;
      • Reduce transport costs to the mill as well as the milling costs;
      • Reduce the environmental cost of restoration of mine tailings;
      • Reduce the environmental footprint of mine tailings and consequently increase the social acceptability of mining project.
    • The study on the hoisting capacities of the shaft of the Chimo Mine property reveals that the components of the internal structure of the shaft could allow hoisting of 4,921 mt / day, i.e. 1.7 M mt / year. The hoisting capacity could be increased to 6,151 mt / day  (2.2 M mt / year) by replacing the guides in place with steel guides. 

  • Ongoing internal engineering studies, developing and producing the design of optimal mining scenarios to minimize costs and recover the most ounce of gold possible, are progressing in line with the results described above. 

  • The potential to increase the resources below and peripheral to the 27 gold zones on the property (FIGURE) remain good.

VAL-D’OR, Quebec, May 07, 2021 (GLOBE NEWSWIRE) -- Cartier Resources Inc. (TSX-V: ECR) (“Cartier”) announces that it has filed on SEDAR the technical report titled " NI 43-101 Technical Report and Mineral Resource Estimate for the Chimo Mine Project, Quebec, Canada ", bearing the date of signature of the May 6th, 2021.

The NI 43-101 compliant report, completed by InnovExplo Inc. for Cartier, presents the results of the updated mineral resource estimate for the Chimo Mine Property situated along the Larder Lake - Cadillac Fault, 45 km to east of Val-d'Or. The report is available on SEDAR and on the Company's website.

Mineralisation on the Chimo Mine Property is comprised of 27 Gold Zones hosted within 17 Gold Structures; the latter grouped within 3 Gold Corridors. The Mineral Resource Estimate to date for the property is presented in the following table (FIGURE):

Total 6,616,000 3.21 684,000 15,240,000 2.77 1,358,000

The volume of rock that contains the gold-bearing zones of the property known to date, for which the resources have been estimated, has a length in the east-west orientation of 1,400 m, a width in the north-south orientation of 675 m and a height of 1,600 m (FIGURE). The resource estimate of the North Gold Corridor, consisting of 9 zones (1A, 1B, 2, 2B, 2W, 3, 3E, 4B and 4B2), of the Central Gold Corridor, consisting of 13 zones (5B, 5B2, 5B3, 5B4, 5C, 5CE, 5M, 5M2, 5M3, 5M4, 5N, 5NE and 6N1) as well as the South Gold Corridor, consisting of 5 zones (6, 6B, 6C, 6P and 6P2), is completed from the information known to date. The majority of resources are located near existing underground openings. However, Zone 6N1 is located 125 m to the southeast and the areas in the eastern sector of the property are located 450 m to the east of the existing underground infrastructure. The potential to increase the resources below and peripheral to the 27 gold zones remains open.

Additional notes on the resource estimate

  1. The gold resource estimate was carried out by Ms. Christine Beausoleil, P. Geo. and Claude Savard, P. Geo. of InnovExplo Inc., who are independent qualified persons within the meaning of NI 43-101.

  2. These mineral resources are not mineral reserves because their economic viability has not been demonstrated. The quantity and grade of Inferred Resources reported in this Mineral Resource Estimate is uncertain in nature and there can be no assurance that any or all of the Inferred Mineral Resources can be converted to Indicated Mineral Resources with further exploration drilling.

  3. The mineral resource estimate of complies with the standards and guidelines in effect of the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) as well as the NI 43-101 standard for the publication of mineral resources.

  4. The requirement of a reasonable prospect of eventual economic extraction is met by having a minimum modeling width for mineralized zones, a cut-off grade based on reasonable inputs and an economic binding volume that lends itself to a potential scenario of underground extraction for undiluted in-situ resources. The constrained volume was achieved with the Deswik Stope Optimizer (" DSO ") using a minimum mining volume of 10 m in width in the longitudinal orientation of the gold zones, by 10 m in height and 2 m in thickness varying up to a maximum of 25 m x 100 m x 15 m. The optimization was carried out using the respective cut-off grade of each of the gold corridors for the indicated and inferred resources. The results of the DSO were then used for the resource estimate statement.

  5. The resource estimate is presented for potential underground scenarios at a cut-off grade of 2.0 g/t Au for the North and South Gold Corridors and 1.5 g/t Au for the Central Gold Corridor. The cut-off grade reflects the geometry and actual width of each of the gold corridors. The cut-off grade was calculated using the following main parameters:
  • Gold price of US $ 1,612 / oz;
  • Exchange rate of US $ 1.34 / CAD $ per troy ounce;
  • Costs relating to the Central Gold Corridor for:
    • Definition drilling of CAD $ 3.00 / t;
    • Development, mining, transport and milling of CAD $ 50.75 / t;
    • Environmental restoration of CAD $ 0.75 / t;
  • Costs relating to the North and South Gold Corridors for:
    • Definition drilling of CAD $ 6.00 / t;
    • Development, mining, transport and milling of CAD $ 75.50 / t;
    • Environmental restoration of CAD $ 1.50 / t; 
  • Cost of transportation of CAD $ 9.80 / t;
  • Cost of milling of CAD $ 17.00 / t;
  • IamGold Corporation royalty cost of CAD $ 21.60 / troy ounce;
  • General and administrative costs of 12.00 $ CAD / t.
  1. The estimate was carried out on 17 3D solids corresponding to the structures constituting the Northern Gold Corridor (structures: 1A, 1B, 2, 3 and 4B), South (structures: 6, 6B, 6C, 6P and 6P2) and Central (structures: 5B, 5B2, 5C, 5M, 5M2, 5N and 6N1) of the Chimo Mine property whose minimum actual thickness is 2.40 m and the average thickness is 7.42 m. The contents of the samples analyzed are used when they are available otherwise in the absence of analytical content, a value of zero is assigned.

  2. The density value of 2.90 g/cm3, supported by measurements, was applied to all gold structures except for structures 1A and 1B, associated to iron formation, where a density value of 3.10 g/cm3 was used.

  3. The estimate was made from a database made up, as of September 1, 2020, of 3,658 holes totaling 296,999 m drilled, 18,612 deviation measurements as well as 83,192 samples analyzed for gold and collected over a core length of 89,805 m representing 30% of the core length drilled. This database contains 2,383 blank and standard samples, inserted for QA/QC by Cartier between November 1, 2016 and September 1, 2020. This database was validated before starting the resource estimate. The estimate was carried out on 17 mineralized structures, intersected by 67,103 m of drilling, having produced 8,611 different gold intersections.

  4. High grade capping was carried out from statistical analysis data at each of the gold structures for values varying between 30 g/t Au and 120 g/t Au from the grade of the composites, also using the grade adjacent material or a value of zero when adjacent material has not been analyzed.

  5. The underground openings (open or backfilled-cemented mine sites, drifts, raises and shafts) were modeled from transverse and longitudinal sections as well as detailed historical geological and mining plans.

  6. This mineral resource estimate was performed using GEOVIA GEMS 6.8.2. Software, using rigid limits on composites. The ordinary kriging method was used to interpolate the block model composed of blocks of dimension 5.0 m x 5.0 m x 5.0 m.

  7. The mineral resource estimate presented here is classified as indicated and inferred resources. The indicated category is defined by a minimum of 3 boreholes located within a 25 m radius and the presumed category is defined by a minimum of 2 boreholes located within a 65 m radius, where there is reasonable continuity of geology and gold grades.

  8. Ounce troy is metric tons multiplied by grade (g/t) and divided by the constant of 31.10348. The number of tonnes has been rounded to the nearest thousand. Any discrepancy in the totals is due to rounding effects. The rounding complies with the recommendations of NI 43-101.

  9. InnovExplo Inc. is not aware of any problem related to the environment, permits, mining titles or related to legal, fiscal, socio-political, commercial issues or any other relevant factor not mentioned in this press release, that could have a significant impact on the mineral resource estimate.

About Chimo Mine Project

  • Cartier holds a 100% interest in the property for which a 1% NSR (“Net Smelter Return”) royalty has been granted to IAMGOLD Corporation. There is no right of first refusal.
  • The property, accessible year-round, is located near many ore processing mills in the Val-d’Or area.
  • Fourteen gold zones were exploited by three producers between 1964 and 1997 for a production of 379 012 ounces of gold.
  • The mining infrastructure consists of a network of drifts over 7 km, distributed over 19 levels and connected by a 5.5 m x 1.8 m three-compartment shaft for a depth of 920 m. The headframe and surface installations were dismantled in 2008, but the 25 kV power line and sandpit are still in place.
  • The study on the hoisting capacities of the shaft of the Chimo Mine property reveals that the components of the internal structure of the shaft could allow hoisting with elongated 20 metric tons (mt) “skips”, 4,921 mt / day at the rate of 10 hours of hoisting operation per 24- hour day, i.e. 1.7 M mt / year. The hoisting capacity in 10 hours of operation / 24 hours, could be increased to 6,151 t / d (2.2 M mt / year) with “skips”' of 25 mt and to 7,381 mt / d (2.6 M mt / year) with “skips” of 30 tm; all mainly by replacing the guides in place with steel guides.
  • Cartier’s drilling to date on the Chimo Mine Property consists of 124 holes totalling 58,054 m and 21,867 samples collected for gold analysis.

Quality Assurance / Quality Control

The analytical results, from Cartier drill holes, were obtained from NQ-caliber core samples crushed up to 80% passing a 10 mesh (2.00 mm) mesh then pulverized up to 90% passing a mesh of 200 mesh (0.07mm). Cartier inserts 5% of the number of samples as certified standards and another 5% as sterile samples to ensure quality control. Samples are analyzed at Techni-Lab (Actlabs), located in Ste-Germaine-Boulé, Quebec. The 50 g pulps are analyzed by fire assay and read by atomic absorption. If i) the result is ≥ 1.0 g/t and <10.0 g/t, a second pulp is analyzed and read by atomic absorption and if ii) the result ≥ 10.0 g/t, the second measurement is performed by gravimetry. For samples containing visible gold, 500 g of rock pulverized up to 90% passing a 140 mesh (0.11 mm) mesh is analyzed by the " Metallic Sieve " method.
