recent pressrelease next pressrelease

(PresseBox) - Copper Mountain Mining Corporation (TSX: CMMC | ASX:C6C) (the ?Company? or ?Copper Mountain? - ) is pleased to announce that it has expanded Copper Mountain Mine?s (?CMM? or the ?Mine?) Mineral Reserve and Mineral Resource and has also optimized the mine plan resulting in a lower strip ratio, longer mine life and smoother production profile.

Highlights from the updated mine plan and Mineral Reserve and Mineral Resource include:

Increased Proven and Probable Mineral Reserve by 12% to 477 million tonnes for contained metal of 2.47 billion pounds of copper and 1.55 million ounces of gold (at average grades of 0.23% Cu and 0.10 g/t Au)

Life of mine strip ratio reduced to 1.58 from 1.82

Mine life increased by 4.5 years to 31 years at current planned production levels

Gil Clausen, Copper Mountain?s President and CEO stated, ?We continue to grow the size and quality of the Copper Mountain Mine Mineral Reserves. entire operation to 1.58 from 1.82.?

Mr. Clausen added, ?We will continue to drill the resources at the Copper Mountain Mine as significant potential exists to further expand all the deposits at a low conversion and discovery cost.

Mineral Reserve and Mineral Resource

As a result of the 2019 exploration and development drilling at the Copper Mountain Mine, the Company has increased the Mine?s Mineral Reserve and Mineral Resource across all categories when compared to the last published February 2019 Mineral Reserve and Mineral Resource, including depletion from production to the end of July 2019. e is included in the Mineral Resource and the effective date of the Mineral Reserve and Mineral Resource is August 1, 2019.

Mineral Reserve Notes:

1. Joint Ore Reserves Committee (JORC) and CIM Definition Standards were followed for Mineral Reserves.

2. Mineral Reserves were generated using the August 1, 2019 mining surface.

3. Mineral Reserves are reported at a 0.10% Cu cut-off grade based on an Equivalent NSR cut-off.

4. Mineral Reserves are reported using long-term copper, gold, and silver prices of $2.75/lb, $1,300/oz, and $16.50/oz, respectively.

5. To define Mineral Reserves, average copper process recoveries of 80% for Main Pit and 88.5% for Main Pit North, gold process recovery of 65% and silver process recovery of 70%.

6. Average bulk density is 2.78 tonnes per cubic metre (t/m3).

7. Stockpile grades are approximations based on grade control results.

8. Stockpile tonnes and grade based on production grade control process.

Mineral Resource Notes:Mineral Resource Notes:

1. Joint Ore Reserves Committee (JORC) and CIM Definition Standards were followed for Mineral Resources.

2. Mineral resources were estimated between the August 1, 2019 mining/topographic surface and Whittle Pit shell generated using US$3.50/lb Cu price

3. Mineral Resources are reported at the 0.10% Cu cut-off (Mineral Reserve) grade and various process cut-off grades dependant on NSR value the mineralization.

4. Average bulk density is 2.78 tonnes per cubic metre (t/m3).

Mine Plan

The Company has updated and optimized the CMM Main Pit and the CMM North Pit, which resulted in lowering the strip ratio (waste to ore) to 1.58. This ratio is lower than the previous February 2019 average life of mine strip ratio of 1.82. The new pit designs, which include the incorporation of the expanded North pit into the production sequence, have enhanced the consistency of production and cost over the plan outlined in the Company?s Technical Report dated February 2019. The Company plans to provide three-year production and cost guidance in January 2020. A summary of mining metrics compared to the prior February 2019 mine plan is provided below:
