Murchison Minerals Ltd. said Oct. 4 that the mineral resource estimate for its Brabant-McKenzie zinc deposit in Saskatchewan has been updated, reflecting an overall increase in tonnage, after including results from 10 new diamond drillholes totaling 5,600 meters completed between February and March.
The deposit is now estimated to host indicated mineral resources of 1.5 million tonnes at 7.46% zinc, 0.70% copper, 0.39% lead and 31.16 g/t of silver, or 10.09% zinc equivalent, and inferred resources of 4.5 million tonnes at 5.99% zinc, 0.62% copper, 0.39% lead and 19.39 g/t of silver, or 7.99% zinc equivalent.
Brabant-McKenzie remains open to depth and laterally, with the exploration target raised to between 9 million and 11 million tonnes grading 7.5% to 9.5% zinc equivalent based on the current geological model. Significant infill opportunities have also been defined from about 610 meters downdip to 950 meters.
The updated resource estimate and new geological model will be used in designing the 2018 drill program at Brabant-McKenzie, which aims to further delineate the deposit's lateral and downdip extensions, infill drill the untested downdip area and convert inferred resources to the indicated category.
