VANCOUVER, British Columbia, April 06, 2022 (GLOBE NEWSWIRE) -- Mirasol Resources Ltd. (TSX-V: MRZ) (OTCPK: MRZLF) (the "Company" or "Mirasol") is pleased to report that the Phase IV diamond drilling program has commenced at the Virginia Silver Project ("Virginia") in the province of Santa Cruz, Argentina. Virginia is operated by the Company and funded by Silver Sands Resources Corp. (CSE: SAND; OTCPK: SSRSF) under an option-to-purchase agreement (see News Release May 21, 2020). If the option is exercised, Mirasol will retain a 19.9% equity ownership in Silver Sands and a 3% NSR royalty (with a buydown to 2% for US$2M).

Mirasol's President Tim Heenan commented: "Together with our partner, we continue to aggressively advance the Virginia expansion drill program. The Phase IV program is anticipated to be completed by the end of the field season in late April. The results will support planning for a partner-funded US$3M exploration program expected to start in late 2022 for the final field season under the option agreement."

The Phase IV program will comprise 14 holes for 1,500m, adding to the 8,867m already completed under the partnership with Silver Sands. The results to date have demonstrated the potential to identify significant mineralization outside of the previously delineated deposits (see amended NI 43 -101 technical report titled "Amended Technical Report, Virginia Project, Santa Cruz Province, Argentina - Initial Silver Mineral Resource Estimate" prepared by D. Earnest and M. Lechner and filed on SEDAR on February 29, 2016).

Phase IV drilling will focus on the following key prospective targets:

• Five drill holes are planned in the southern parts of Ely Central and Ely North to tighten the drill spacing and to close gaps between the Ely North and Ely South deposits. If continuity of mineralization is demonstrated, Ely Central is expected to support the expansion of the resource between the two deposits.
• Two drill holes are planned at Margarita to follow up on the significant silver intersection from the recent Phase III drill campaign, which returned 2.65m at 1,456 g/t Ag in hole MR-DDH-003 (see News Release February 1, 2022). The planned holes will step out 50m and 100m to the northeast and test the potential strike continuity of the mineralization in this structure at the same depth. Deeper holes may also be completed to test the potential downdip extent of the mineralization. Further drilling success at Margarita could significantly add to the current resource at Virginia.
• Two drill holes are planned at Martina NW and Martina Central to test gaps along this trend and between these two zones. Drilling will continue testing the potential continuity of the northwest structure along a high chargeability anomaly.
• Scout drilling is also planned at the Patricia and Daniela targets to test for the potential downdip extension of the mineralized structure below high-grade silver samples collected on surface and in trenches. Surface samples at these prospects have returned the highest silver values to date with up to 29,000 ppm Ag from aligned float blocks (see news release October 29, 2020).
• Finally, three drill holes are planned to follow up on the Santa Rita East target, where drilling to date has only tested the depth extension of these structures to less than 50m vertically below surface.
  

The results from the Virginia Phase IV drill program will be announced as they are received and interpreted.
