Drill holes CURI-358 and CURI-360 were designed to test the outer margins of the Indicated category material and to further assess the pit wall geology. These drill holes confirmed modelling previously done along the margins of the deposit and provide excellent geological control for future modelling studies. Drill hole CURI-358 intersected mineralization in the footwall felsic autoclastic volcanic rocks from 96.13 to 109.00 metres, grading 0.03% copper, 0.15 g/t gold, 0.52% zinc, 6.7 g/t silver, and 0.02% lead (0.36% CuEq) over 8.37 metres approximate true thickness. Drill hole CURI-360 intersected mineralized fine-grained sediments from 50.08 to 51.96 metres, grading 0.03% copper, 2.05 g/t gold, 0.41% zinc, 91.5 g/t silver, and 0.19% lead (2.30% CuEq) over 1.50 metres approximate true thickness.
All results from the current infill definition drilling program will be used to update the Mineral Resource estimate for the El Domo deposit in 2021. The updated Mineral Resource estimate will be part of the ongoing feasibility study for the development of the El Domo deposit (see
