Capitan Mining Inc. (TSX-V: CAPT) is pleased to report results for four reverse-circulation drill holes from the Capitan oxide-gold deposit, at its 100%-owned Peñoles project in Durango, Mexico.
All holes reported herein were designed to either extend Capitan style mineralization down-dip/down plunge along section lines, or as infill hole(s) that attempt to refine the boundaries and extend the continuity, of high-grade shoots that are nested within the Capitan deposit mineralized envelope.
Step-out holes: Expanding the Capitan Zone Footprint
Drillholes 21-CARC-30, 31, and 32 were designed to expand Hanging wall style and Capitan Style, oxide mineralization down-dip along section lines 550, 100, and 450 respectively (see Figure 1).
All drillholes successfully intersected both Hanging Wall style and Capitan style mineralization, extending both zones between 70 and 170m down-dip, along section. Additionally, all holes intersected and extended the oxide gold envelope down-dip, with sulphide mineralization only being reached towards the termination of holes 21-CARC-30 and 31 (see Figure 2a). The best results intersected include 29m of 0.55g/t Aueq within a continuous interval of 187.5m grading 0.24 g/t Aueq in hole 21-CARC-31, and 41.1m of 0.31 g/t Aueq in hole 21-CARC-32, both coming from the Capitan Main Zone.
Infill Holes: Confirming and expanding the Continuity of high grade shoots
Drillhole 21-CARC-33 was designed to test the continuity of a higher-grade shoot of mineralization that has been traced for over 300m down plunge and over 100m width, which typically returns grades greater than 1 g/t Au. This zone is one of three that have been identified within the Capitan deposit mineralized envelope, and typically plunge shallow (20-25 degrees) to the southwest. The hole successfully intersected the higher-grade shoot, returning 56.4m at 0.75 g/t Aueq, including a higher-grade interval of 10.7m grading 1.19 g/t Aueq, extending the higher-grade shoot down plunge by approximately 40m from drillhole 20-CARC-12, which returned 36.5m of 0.91 g/t Aueq within a larger interval of 73.15m of 0.63 g/t Aueq. Additionally, hole 21-CARC-33 confirms that silver mineralization is continuing to increase at depth, along the western margin of the higher-grade shoot, with values of 16.7 g/t Ag over 10.7m being returned.
Spring-Summer exploration program
Capitan completed its initial 6,000-metre drill program in early 2021 and began a second stage of drilling in the spring that will continue through the summer working on expanding mineralization in the Capitan gold zone. The Company expects to drill approximately 6,000 metres of reverse-circulation drilling during this period as well as to continue surface exploration work on additional targets within the Peñoles project in order to advance them towards a drill stage.
Capitan’s CEO, Alberto Orozco, stated: “We are very pleased with the continuity that the Capitan gold zone has shown with each batch of drill holes that we have released. This additional drilling has not only expanded the presence of gold mineralization in the Capitan zone, but it has also helped our geological team have a better understanding of the geology and structural controls for the mineralization at the Capitan gold zone. The presence of silver mineralization in that zone is one of the points we continue to study.”

Note: Only drill intercept lengths are reported in the table. Drill holes are designed to cut the mineralized zones as close to true width as possible, with true widths ranging from 70-95% of the reported drilled length.
* Gold equivalent calculated at 80:1 ratio
NSV: No significant values.
MIX: Total length of mineralization that includes a top oxide interval and a bottom sulphide interval.

Qualified Person & QA/QC:
The scientific and technical data contained in this news release pertaining to the Peñoles Project was reviewed and approved by Marc Idziszek, P.Geo, a non-independent qualified person to Capitan Mining, who is responsible for ensuring that the technical information provided in this news release is accurate and who acts as a “qualified person” under National Instrument 43-101 Standards of Disclosure for Mineral Projects.
Capitan Mining Inc. has a Quality Assurance/Quality Control program that includes insertion and verification of control samples including standard reference material, blanks and duplicates consistent with industry standards.
RC drill samples from the Peñoles Project are collected and split at the drill site using a Gilson Universal Splitter. The samples are stored in either plastic bags (dry) or micropore bags (wet) and secured with plastic zip-ties and then transported to the preparation laboratory of Bureau Veritas in Hermosillo, Sonora. The sample pulps are then transported to the Bureau Veritas’ laboratory in Vancouver, where they are assayed for gold by fire assay with atomic absorption finish (FA430 assay method code; 0.005 to 10 ppm detection limit). Samples over 10 ppm Au are assayed with gravimetric finish (Assay code FA530). All samples are also assayed by ICP-ES (code AQ300) for a suite of 33 elements.
All summarized intervals reported in this press release were calculated using a 0.10 ppm Au cut-off grade. Intervals contain no more than 3 metres of internal dilution. High grades have not been capped.
