Accordingly, in June of 2012, Bralorne commissioned Beacon Hill Consultants (1988) Ltd. to conduct a Preliminary Economic Assessment (PEA) on the property and devise a plan for expanding production. The PEA delineated a NI 43-101 compliant resource estimate of measured and indicated resources totalling 154,750 tonnes of grading 9.11 g/t Au (0.266 oz Au/t) and an additional 246,835 tonnes grading 8.78 g Au/t (0.256 oz Au/t) classified as inferred resources. The production ramp-up plan envisioned will require additional resources to be delineated from exploration activities below the 800 level down to 1000 level in the BK Zone. The PEA presented an exploration and development plan aimed at defining additional resources to warrant a production increase to 250tpd. The recommended plan includes the following:
- A treatment facility to treat arsenic water from underground openings;
- A pumping system to dewater the workings from 800L to 1000L;
- A ramp to 1000L;
- Rehabilitation of a shaft;
- Rehabilitation of drifts and raises;
- An extensive exploration program from both surface and underground;
- Drifting and raising to outline resources;
Assuming sufficient resources will be delineated, the work required in order to achieve the proposed increase in production includes upgrading the process plant to allow for 250tpd production rate and upgrading the Tailing Storage Facility for storing the additional tailings resulting from the higher production rate.
Upon approval of permitting from the BC Government, a treatment plant including dewatering facilities can be constructed and once operational the area from 800L to 1000L can be dewatered. The recommended plan includes a mine production decline to acess the 10 level, and rehabilitation of one old shaft as soon as the water level is reduced for safe operation.
Bralorne has developed a preliminary project schedule to determine when it is feasible to increase the production should sufficient resources be delineated.
