Tier One Silver reported results from drill holes 4 - 6 at the Curibaya project in southern Peru. Drill hole 6 targeted the Madre structure, which has emerged as the primary target structure on the project to-date, and intersected 1 metre (m) of 1,480.5 g/t silver equivalent (AgEq) within a broader interval of 3.5 m of 442.5 g/t AgEq at a drill depth of 107.5 m to 111 m. The company's technical team believes the result from hole 6 demonstrates the high-grade potential along the 1.4-kilometre (km) long Madre structure, as defined by mapping and remote sensing data. Currently, there are results from three drill holes along the Madre structure pending, including a first drill hole into the diatreme dome complex that the technical team believes is the potential source for precious metal mineralization across the property. Drill holes 4 and 5 targeted the Sama and Sambalay structures, respectively, and both drill holes encountered significant silver mineralization in multiple parallel structures. Hole 5 is the second drill hole to test the 900 m long Sambalay structural corridor and intersected 1 m of 579.6 g/t AgEq, 0.5 m of 266.8 g/t AgEq, 1 m of 88.1 g/t AgEq and 11 m of 37.8 g/t AgEq. Hole 4 was the first drill hole to test the Sama structure and intersected 1 m of 211.6 g/t AgEq within a broader interval of 3 m of 96.4 g/t AgEq, 1m of 137.5 g/t AgEq, 1 m of 99.6 g/t AgEq and 0.5 m of 172.8 g/t AgEq. The results from drill holes 4 - 6 demonstrate that significant precious metal mineralization extends to depth below mineralization encountered in surface channel samples. In addition, hole 6 was the first drill hole to test the margin of the high chargeability anomaly that, in part, defines the Madre structural corridor. The positive correlation between high-grade mineralization in drill hole 6 and the margins of the chargeability anomaly further strengthens the company's targeting efforts at depth. To date, the company has drilled a total of 12 holes into four of the five precious metal feeder structures for a total of 4,473 m, with results pending for six holes. The company plans to drill an additional 1,000 m in three holes along the Madre structure, prior to a pause in drilling for the rainy season beginning in mid-December. The company expects to resume drilling at Curibaya at the end of first quarter 2022. In addition, a drill permit expansion is in progress to include the Cambaya structures, to the northeast of current drilling, which the company plans to drill test in 2022.
