Orosur Mining Inc. announce an update on the progress of Minera Anzá's drilling campaign currently underway at the Company's Anzá project in Colombia. Assay results for four additional diamond drillholes have been received from the ALS laboratory in Lima, Peru, MAP-079, 080, 081 and 082. Significant results from MAP-079 and MAP-082 include: MAP-079 23.75m @ 17.40g/t Au, 1.84g/t Ag, 0.19% Zn MAP-082 29.45m @ 2.50g/t Au, 1.95g/t Ag, 1.08% Zn. MAP-080 and MAP-081contained no significant intersections. All holes were drilled to better define the geological controls upon gold and base metal mineralisation that had been identified during previous drilling campaigns, but also to extend or to close off such mineralisation. All were successful in addressing their objectives and have added important additional information to the understanding of the litho-structural controls upon the mineralisation at APTA that has allowed later drilling to be better focussed. The company currently has five diamond drill rigs operating at the APTA prospect, with close to 6,000m having been completed since November 2020 across 18 holes, both completed and underway. Drilling is now focussed on a combination of understanding the geological controls upon mineralisation, expansion of the mineralised zones, and infill drilling to demonstrate continuity. Visually, results continue to appear positive, but the Company remains subject to delayed assay results, with over 2000 samples currently in the laboratory awaiting assay. It was noted previously that assay turnaround times from the ALS laboratory in Peru had blown out substantially from normal expectations as a result of Covid-19 related staff shortages at the laboratory. This performance had begun to improve in February and March. However, Peru, like most countries in the region is now experiencing a major third wave of Covid-19 and as a result, laboratory turnaround times are now well in excess of previous delayed schedules. There is no indication that this will improve in the near term. Following a lull in February and March, Colombia is now experiencing a very serious third wave of Covid-19, especially in the major cities of Bogota and Medellin, where curfews and lockdowns are now in place. However, mining has been declared an essential industry and as such is permitted to continue, which the Company has been able to do via strict Covid operating protocols and an exhaustive testing regime. Given the success thus far of its operating protocols, the Company has taken the decision to expand its regional field work across its wider licence package in order to identify targets for future follow up. The licence and application package at Anzá contains over 20km of strike of the Aragon Fault, which is thought to control mineralisation at APTA, and potentially a similar strike length of the N-S Tocuman Fault that may be the primary conduit from the La Cejita intrusive complex to the north of APTA. However, almost all exploration work undertaken thus far by the Company and previous operators has been focussed on roughly 500m strike at the APTA prospect with some minor work at Charrascala. Much of the remainder of the licence package remains essentially untouched. Several regional programs are underway or planned: Bulk Leach Extractable Gold sampling programs have been underway across the wider APTA licence and surrounding areas for some weeks. BLEG is a sampling method capable of detecting extremely low levels of gold and is a broad scale regional tool for identifying attractive zones for further follow up. Detailed geological mapping and sampling has been ongoing across the APTA licence for some months. The scope of this work is to better understand the local lithology and structures that are controlling mineralisation in the APTA area. Several field teams have mobilised to the NE of the project area, outside the APTA licence, which is postulated to host the NE extension of the Aragon Fault, to conduct major mapping and sampling programs. The Company has engaged international mining consulting firm CSA Global to advise in an external expert capacity, with the first task being to carry out an analysis of all previous drilling to ensure that it was completed in a manner consistent with the Canadian standard NI43-101 and thus amenable to be included in a resource estimate in the future. The outcome of this work was positive, with CSA noting that all previous drilling was of a high standard, and that with some minor modifications would be amenable to be included in a resource estimate in future when that is warranted.
