Orosur Mining Inc. announced an update on the Company's Anz? Project in Colombia. A major phase of drilling was undertaken at Anz? from October 2020 through to the end of June 2021, designed to confirm the potential of the core APTA deposit at Anz? and to provide sufficient information to allow the Company's JV partner Minera Monte ?guila SAS ("Monte ?guila") to move forward into the next annual period of the Exploration Agreement with Venture Option ("Exploration Agreement"). Once this was achieved, the number of drill rigs was reduced from five to one, with focus shifting to better understanding the regional picture and to mapping and sampling of the other licences and applications to identify targets for the next phase of work. Reducing to one drill rig allowed geologists to be redeployed to mapping activities, with the remaining drill rig focussed near the margins of the APTA deposit, to address several regional stratigraphic questions and to provide greater guidance as to the controls on the previously identified high grade mineralisation at APTA. Assay results for five additional diamond drillholes have been received from the ALS laboratory in Lima, Peru, MAP-092 to MAP-096. Highlighted results from these holes include: MAP-093 14.85m @ 1.60g/t Au, 1.08g/t Ag, 0.79% Zn, MAP-094 8.55m @ 0.96g/t Au, 5.88g/t Ag, 0.34%Zn, 5.35m @ 1.17g/t Au, 2.18g/t Ay, 0.79% Zn, 10.70m @ 1.08g/t Au, 0.24g/t Ag, 0.03% Zn, MAP-096 2.70m @ 2.84g/t Au, 1.12g/t Ag, 0.07%Zn and 51.55m @ 1.32g/t Au, 1.34g/t Ag, 0.35% Zn. Holes MAP-092 and MAP-095 were collared well away from the known mineralisation at APTA and were drilled in the opposite direction to current drilling, from west to east. Both of these holes were designed to assess the regional geology and to test the idea that the target stratigraphy identified at APTA represented the eastern limb of an anticline and would be repeated to the west. These holes were purely stratigraphic and were not expected to intersect mineralisation. Hole MAP-093 was targeted to test the down dip continuity of the stratigraphic section related to the historical La Pastorera gypsum mine. The footwall breccia was identified and was mineralised to a moderate degree. Hole MAP-094 was targeted to test the southern extension of a high-grade pod defined in previous drilling. A substantial thickness of moderately mineralised breccia was identified.
