The fully funded program will use two diamond drill rigs to complete approximately 10,000m of drilling. This drilling program will advance the Klaza project towards pre-feasibility by achieving key objectives which include: infill resource definition drilling (9,000 m in 44 holes) to convert a greater portion of the inferred mineral resources to indicated mineral resources; Discovery-focused exploration drilling (1,000m in 5 holes) on high-grade gold-silver epithermal targets including the Rusk and Western BRX Extension targets; Additional target evaluations, without drilling, at the Rusk East, Dade, Bear and Sked prospects; and, Continuation of studies related to metallurgy, engineering and basic permits.
“Following a successful infill drilling program in 2021, work in 2022 is designed to establish Indicated Resources in priority areas of the 2020 PEA and will lead to an updated mineral resource estimate and pre-feasibility study in mid -2023,” said
Infill drilling of the Klaza deposit
Infill drilling of the Klaza deposit will focus on upgrading inferred resources to indicated resources. Based on the most recent mineral resource estimate released in 2018, 60% of Klaza’s total mineral resources are classified as indicated and 40% as inferred. A total of 6,000m of infill drilling in 31 holes has been completed in 2021 with a further 9,000m in 44 holes planned for work in 2022. This drilling, combined with additional geotechnical, metallurgical and environmental monitoring, will continue to support the pre-feasibility study which should be completed in 2023.
Exploration drilling is planned on the Rusk and Western BRX Extension targets. Mineralization at the Rusk target was discovered by a drillhole closeout in 2020, which spanned a new vein complex located approximately 3 km south of the Klaza deposit. The discovery holes were followed by ten drill holes in 2021, tracing mineralization at the core of the target over a strike length of 300m. Work in 2022 on this target will further assess the strike potential of major structures.
Drilling at the Western BRX extension will target the eastern projection of a silver-rich vein discovered in KL-21-492 that returned 1,160 g/t silver, 8.4% lead and 5.2% zinc on 0.54 m (see the press release of the
An exploration hole may also test an undrilled portion of the Kelly porphyry target, which lies southeast of the vein system hosting the Klaza deposit. Following a comprehensive analysis of the results of previous work done in this area, a single hole was recommended based on vectors including vein styles, lithogeochemical characteristics and geophysical signatures.
Regional target assessments
In addition to the drill program, work in 2022 will evaluate four other promising prospects on the Klaza property, which include the Rusk East, Dade, Bear and Sked targets. Depending on the results, these prospects could be drill tested later in the season.
