Over 83,000 meters of resource upgrade, expansion drilling north of 60 Mining News – July 16, 2021
Benchmark Metals Inc. plans to complete well over 100,000 meters of drilling at Lawyers, including more than 83,000 meters planned for the upgrade and expansion of the three gold and silver deposits defined so far on the road accessible project in northern British Columbia.
According to a calculation released in May, the Cliff Creek, AGB and Dukes Ridge deposits at Lawyers contain 40.3 million metric tonnes of indicated resources with an average of 1.19 grams per metric tonne (1.55 million ounces) of gold and 38.7 g / t (50.2 million ounces) silver; plus 16.2 million metric tonnes of inferred resources containing an average of 1.19 g / t (620,000 oz) of gold and 34.7 g / t (18.1 million ounces) of silver.
Much of this year’s 100,000-meter drill program will focus on upgrading inferred resources to the higher confidence indicated category and test expansion targets at all three deposits in preparation for development. ” an expanded and improved resource to be included in a future feasibility study on mine development at Avocats.
“Geological modeling has demarcated the deposit zones for significant expansion,” said Benchmark Metals CEO John Williamson.
These expansion zones include the south end of AGB, where expansion drilling in late 2020 intersected large sections of strong gold and silver mineralization.
20AGBDD039, the southernmost hole drilled at AGB, intersected 66 meters with an average of 2.34 g / t gold and 51.5 g / t silver, including a five-meter sub-interval with an average of 15.31 g / t gold and 180.8 g / t silver.
Benchmark indicates that a large zone of strong mineralization is emerging at the southern end of the 650 meter long AGB zone which remains open at depth and along strike.
Seeking to significantly expand AGB’s contribution to Lawyers’ resources, the company plans to test these expansion areas with a substantial portion of the 13,700 meters of resource drilling planned at AGB.
Drilling in late 2020 also produced strong gold in the southern part of the Cliff Creek deposit. 20CCDD104, one of the holes drilled in the Cliff Creek South area, intersected 107.8 meters at an average grade of 2 g / t gold and 46.8 g / t silver. Another hole drilled outside the pit shell modeled in this area, 20CCDD098, intersected 38.1 meters with an average of 5.71 g / t gold and 7.8 g / t gold. silver.
Benchmark says these results demonstrate the significant potential to extend Cliff Creek to the southeast and to depth.
The company says a similar scenario also exists at the north end of Cliff Creek North (CCN) where the pit remains open for expansion. Approximately 24,000 meters of expansion drilling is planned at Cliff Creek.
The Dukes Ridge deposit also remains open, especially at depth. The deepest part of the Dukes Ridge deposit is only 200 vertical meters below surface and drilling intersected several high grade intersections towards the base of the modeled pit. Benchmark plans to drill at least 9,000 meters this year targeting this significant potential for expansion.
Additional growth potential could also be realized in a junction zone between Dukes Ridge and Cliff Creek as we continue to drill this mineralized corridor.
In addition to resource expansion drilling, Benchmark plans to complete approximately 37,000 meters of infill drilling to upgrade inferred resources at all three deposits.
In addition to the nearly 84,000 meters of resource drilling on record for this year, Benchmark plans to complete 50,000 meters of exploration drilling on several discovery targets on the 56 square mile (144 square kilometers) Lawyers property.
This includes 12,500 meters of drilling at Marmot and Marmot East, where grab samples containing up to 61.3 g / t gold and 3,890 g / t silver were taken, and the Marmot discovery hole 2020, 20MLDD005, cut 101 meters with an average of 0.55 g / t gold and 21.8 g / t silver.
This year’s drilling could establish an important new resource at Marmot.
“The Marmot targets have significant potential to generate ounces of gold and silver of the same size and scale as the Cliff Creek deposit,” said Williamson.
Benchmark Metals chairman Jim Greig told Mining News the company may decide to increase the already massive 2021 drilling program at Lawyers to nearly 200,000 meters.
