Massive sulphide mineralization was intersected from 115.46 to 130.40 metres, grading 6.49% copper, 1.64 g/t gold, 1.52% zinc, 35.5 g/t silver, and 0.16% lead (8.34% CuEq). Two subsets of higher-grade massive sulphide mineralization were intersected from 115.46 to 118.24 metres and 124.50 to 130.40 metres. The first intercept graded 1.63% copper, 1.40 g/t gold, 1.62% zinc, 33.2 g/t silver, and 0.12% lead (3.33% CuEq), and the second intercept graded 14.29% copper, 2.11 g/t gold, 1.95% zinc, 34.3 g/t silver, and 0.16% lead (16.54% CuEq). The drill hole was lost in a fault zone at 130.40 metres while still in mineralization and did not reach targeted completion depth.

Drill holes CURI-363 and CURI-365 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-363 intersected a thick section of mineralization in the footwall felsic autoclastic volcanic rocks from 54.54 to 90.95 metres with two intervals providing low-grade intercepts. The first intercept was from 54.54 to 59.68 metres, grading 0.06% copper, 0.19 g/t gold, 0.81% zinc, 12.0 g/t silver, and 0.18% lead (0.57% CuEq) over 3.34 metres approximate true thickness. The second intercept was from 69.62 to 84.89 metres, grading 0.05% copper, 0.02 g/t gold, 0.53% zinc, 0.8 g/t silver and 0.02% lead (0.24% CuEq) over 9.93 metres approximate true thickness.
Drill hole CURI-365 also intersected mineralization in the footwall felsic autoclastic volcanic rocks from 39.72 to 51.52 metres, grading 0.03% copper, 1.06 g/t gold, 0.34% zinc, 69.0 g/t silver, and 0.15% lead (1.45% CuEq) over 8.26 metres approximate true thickness. A high-grade subset occurs from 39.72 to 45.56 metres, grading 0.03% copper, 1.61 g/t gold, 0.42% zinc, 119.8 g/t silver, and 0.17% lead (2.29% CuEq) over 4.09 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
