VAL-D’OR, Québec, Sept. 22, 2020 (GLOBE NEWSWIRE) -- Cartier Resources Inc. (TSX-V: ECR) (“Cartier”) reports the results of an engineering study on the hoisting capacity of the underground mining infrastructure on the Chimo Mine Property. This property, owned 100% by Cartier, is located 45 km east of the Val-d’Or mining camp.
The study reveals that the components of the internal shaft structure could be used to hoist skips with a loading capacity of 20 metrics tonnes each, travelling at a cruising speed of 2,200 feet/minute (40 km/h). This hoisting rate would raise 492 mt/hour of rock to the surface for a total of 4,921 mt/day in 10 hours of hoisting operations per 24-hour day or 1.7 M mt/year.
To date, two internal engineering studies have been completed with positive findings, including the study that is the subject of this press release. Two other internal engineering studies are still underway, as well as an internal preparatory study for a new mineral resource estimate on the Chimo Mine Property.
No PEA, PFS or FS has been completed and disclosure of results from this internal study does not support or imply the technical feasibility and/or economic viability of the project. In addition, while current mineral resource estimates have been completed on separate zones on the property, mineral resources that are not mineral reserves do not have demonstrated economic viability.
Table of current and future features of the shaft infrastructure on the Chimo Mine Property:
Current shaft features | |
Dimensions of excavated shaft | 914 m x 6 m x 2.7 m (represents 15,000 m³ of excavated rock) |
3 compartments | Each measuring 5'0" x 5'6" |
State of internal rock walls | In good condition at the time of mine closure |
Internal shaft structure | 8" x 8" beams of Douglas (BC) fir |
State of internal shaft components | In good condition at the time of mine closure |
Wood submerged under oxygen-free water remains intact* from deterioration for decades | |
Key additional features required | |
Weight of hoisted rock material | 4,921 mt/day in 10 hours of operation per 24-hour period |
492 mt/hour | |
Type of skips | 2 skips with a loading capacity of 20 t each, in compartments Nos. 2 and 3 |
Each skip is 14 m height instead including the cage | |
Number of hoisted skips per hour | 30 |
Skip cruising speed | 2,200 ft/min (40 km/h) |
Type of cage | 4-deck Mary Ann-type cage with 36-person capacity in compartment No. 1 |
Height of headframe | 57 m |
Weight suspended below wheel | 56 mt |
Type of hoist | Drum hoist 5.1 m in diameter with AC drive force of 4880 RMS HP |
Type of hoisting cable | Single cable 56 mm in diameter or multi-cable system |
*: Careful inspection of shaft components will be required, as will the replacement or reinforcement of components that do not meet the standards. |
