Drill holes CURI-371, CURI-375, CURI-376, CURI-380 and CURI-383 were designed for collection of geomechanical data to assist in future mine planning, as part of the ongoing feasibility study. Drill hole CURI-388 intersected a low-grade section of footwall mineralized felsic autoclastic volcanic rocks 102.04 to 112.39 metres, grading 0.04% copper, 0.17 g/t gold, 0.09% zinc, 4.0 g/t silver and 0.02% lead (0.21% CuEq) for an approximate true thickness of 6.73 metres. All results from the completed infill definition drilling program are to be used in updating the Mineral Resource estimate for El Domo in 2021. The updated Mineral Resource estimate will be part of the ongoing feasibility study for the development of El Domo. Upon completion of infill and geomechanical drilling required to support the ongoing Feasibility Study with a Mineral Resource estimate update and the provision of metallurgical samples, a drill rig was tasked to restart the regional exploration drilling program. A total of 4,000 metres is budgeted in 2021 with drilling having re-commenced on the El Panecillo target in late April 2021, approximately 1.5 kilometres east of El Domo. El Panecillo is a VMS target being drilled for the first time in the same favourable volcanic-sedimentary strata that hosts El Domo. The first drill hole, CREG-004, has been completed with CREG-005 in progress. Results from the regional exploration work program will be released after receipt from the laboratory and when results pass a rigorous internal quality assurance and quality control ("QAQC") processes.
