Cartier Publishes its First Mineral Resource Estimate of the Central Gold Corridor on the Chimo Mine property
Highlights:The Central Gold Corridor resource estimate for the Chimo Mine property (FIGURE 1) was produced using a gold price of US $ 1,292 per ounce and a cut-off grade of 2.5 g/t Au: 3,263,300 tonnes at an average grade of 4.40 g/t Au for a total of 461,280 ounces of gold in the indicated resource category;3,681,600 tonnes at an average grade of 3.53 g/t Au for a total of 417,250 ounces of gold in the inferred resource category; Work on expanding resources is underway via: The estimate of the resources of the North Gold Corridor and South Gold Corridor;The preparation of exploration drilling of the geometrical extensions below the new Zones 5B4-5M4-5NE, which will start on November 20th using 2 drill rigs (FIGURE 1).VAL D’OR, Quebec, Nov. 05, 2019 (GLOBE NEWSWIRE) — Cartier Resources Inc. (TSX-V: ECR) (“Cartier”) announces the results of the mineral resource estimate of the Central Gold Corridor of the Chimo Mine property, located 45 km east of Val-d’Or. The estimate, completed and made available on November 4th, 2019, was prepared by Mr. Christian D’Amours, P. Geo., B. A. Sc. from GeoPointCom Inc., an independent Qualified Person as defined by NI 43-101.“These resources, with existing underground infrastructure, are key elements of the Company’s short-term growth strategy,” commented Philippe Cloutier, President and Chief Executive Officer, adding that “this represents only a portion of the potential of the Chimo Mine property. The resource estimates for the North and South Gold Corridors are in progress and are in addition to, the potential that can be outlined via drilling soon to be launched below Zones 5B4-5M4-5NE, which reported excellent results last June.”The table of the sensitivity of the cut-off grade on the gold resources (FIGURE 1) is presented below:The table above illustrates the sensitivity of this mineral resource estimate to different cut-off grades for an underground operation scenario with reasonable outlook for economic extraction. The reader is cautioned that the figures provided in this table should not be interpreted as a statement on mineral resources. Quantities and estimated grades for different cut-off grades are presented for the sole purpose of demonstrating the sensitivity of the resource model to the choice of a specific cut-off grade.Mineralization of the Chimo Mine property consists of 25 gold zones within 16 gold structures, that are grouped into three gold bearing corridors (FIGURE 1). The results of this release present only the resource estimate of the Central Gold Corridor, consisting of Zones 5B, 5B2, 5B4, 5C, 5M, 5M2, 5M3, 5M4, 5N, 5NE and 6N1. Zones 5B, 5B2, 5C, 5M, 5M2 and 5N are located, in part, within the infrastructure of the former Chimo mine, while Zone 6N1 is located 125 m to the south and Zones 5B4 – 5M4 – 5NE are located 450 m to the east.Zones 5B4-5M4-5NE, recently developed and particularly through the excellent results of June 2019, have led to the development of new resources in the eastern part of the property. This new area, with strong discovery potential under Zones 5B4 – 5M4 – 5NE (FIGURE 1), will be drilled again starting November 20th, 2019.The resource estimate for the Northern Gold Corridor consisting of Zones 1A, 1B, 2B, 2, 2W, 3, 3E, 3W, 4B and 4B2 and the Southern Gold Corridor, consisting of Zones 6, 6B, 6P and 6P2, is in progress.Additional notes on resource estimatesThese mineral resources are not mineral reserves because their economic viability has not been demonstrated. The amount and content of inferred resources reported in this mineral resource estimate is uncertain and there can be no assurance that some or all of the Inferred Mineral Resources may be converted to indicated mineral resources with further exploration drilling.
The mineral resource estimate is in accordance with the current standards and guidelines of the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) and NI 43-101 for the publication of mineral resources.
Resources are presented in situ for an undiluted underground operation scenario and considered to have reasonable outlook for economic extraction.
A cut-off grade of 2.5 g/t Au was used to estimate mineral resources from calculations made with the following key parameters:
gold price of US $ 1,292 / oz exchange rate of US $ 1.3 / CAN per troy ounce cost of mining and hoisting $ 90 / t transportation cost of $ 20 / t milling cost of $ 25 / t recovery percentage of 90% Given the physical properties of the minerals (quartz and arsenopyrite) associated with gold, it is reasonable to expect a 35% reduction in transportation and milling costs if a material sorting plan is in operation at surface on the Chimo Mine site. This cost reduction produces a calculation of 2.5 g/t Au for the cut-off grade. It is important to note that these costs are dynamic and may vary over time. Therefore, they must be re-evaluated regularly according to market conditions. The author estimates that the threshold of 2.5 g/t Au for the cut-off grade represents the fair value of the potential of this project and that this value constitutes the reference value for this study. The selection of reasonable prospective parameters, which assume that some or all of the estimated resources could potentially be extracted, is based on a bulk underground mining scenario involving a daily extraction rate of approximately 2,000 to 3,000 tonnes.
The density value of 2.8 g/cm3 was used.
The estimate was made from a database as July 2nd 2019 of 3,429 drill holes totaling 279,670 m drilled, 13,477 deviation (hole orientation) measurements and 79,236 samples analyzed for gold and collected over a core length of 85 647 m representing 35% of the drilled core length. This database contains 2,107 blank and standard samples, inserted by Cartier between November 1st, 2016 and July 2nd, 2019. This database was validated before starting the resource estimate. The estimate was carried out on seven mineralized structures intersected by 51,029 m of drilling, producing 5,364 different gold intersections.
A high grade cap of 30 g/t Au (5M2 and 6N1 structures), 50 g/t Au (5M and 5N structures) and 110 g/t Au (5B structure) was applied at for the interpolation on composites located more than 15 m from the center of the estimated cell.
Underground openings (open and backfilled-cemented stopes, drifts, raises and shafts) were modeled from cross-sectional and longitudinal sections as well as detailed historical geological and mining plans. Historical underground production has been subtracted from the resource estimate. The reconciliation of the resource estimate to the detailed feed information at the plant between 1990 and 1996 shows only a difference of 4.92% in the tonnage extracted and 2.15% in ounces produced.
This mineral resource estimate has been prepared using the software GeoticMine (v.1.2.14) and Isatis (v.1208.3). GeoticMine has been used for 3D modeling of topographic and bedrock surfaces, mined sites and various underground openings as well as the interpretation of gold structures. Each structure has been defined by individual meshes. Isatis was used for geostatistics and resource estimation on a percent block model. Statistical studies were performed with NCSS (v. 12) and Microsoft Excel software. The grade interpolation was performed using the ordinary kriging method, based on 1.0 m composites and 10 m x 10 m x 10 m blocks.
The mineral resource estimate presented here is classified as Inferred and Indicated. The Indicated Mineral Resource category is defined by interpolation using a research ellipsoid with an average radius of 20 m for pass 1. The category of inferred mineral resources is defined by interpolation using a research ellipsoid having an average radius of 40 m for pass 2 and 80 m for pass 3. Cells that were not estimated during a pass were estimated in the following passes, except for pass 3.
The number of metric tons has been rounded to the nearest hundred and the metal content is presented in troy ounce (ton x grade / 31.1035) rounded to the nearest tenth.
GeoPointCom is not aware of any environmental, permit, mining claim or legal, tax, socio-political, commercial or other relevant matter not mentioned in this news release, which could have a significant impact on the mineral resource estimate.Chimo Mine Project HighlightsCartier holds a 100% interest in the property for which 1% NSR (” Net Smelter Return ”) royalty has been granted to IamGold Corporation. No rights of first refusal (” buy-back ”) have been granted. The property, which is accessible year-round, is located near 6 mils in the Val-d’Or area. Fourteen gold zones were exploited by 3 producers between 1964 and 1997 for a production of 379,012 ounces of gold (MERN DV 85-05 to DV-97-01). 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 3 compartment shaft with a depth of 920 m. The headframe and the surface installations were dismantled in 2008 but the 25 kV power line and the sandpit are still in place. The recent drilling of Phases I, II and III, completed to date by Cartier on the Chimo Mine property, consists of 109 holes totaling 49,251 m. This work demonstrated the continuity of the main 5B and 5M gold zones under the existing mining infrastructure, explored the extensions of 19 gold zones peripheral to the main zones and explored the extensions of the 7 gold zones that were prioritized; which allowed the discovery of the Zones 5B4-5M4-5NE (FIGURE 1) and to develop the potential of Zone 6N1. These areas have excellent potential to deliver future discoveries.Qualified Persons
