Minera IRL Completes Phase 1 of the Ongoing Long-Hole Drilling Campaign at the Corihuarmi Gold Mine

LIMA, Peru, July 31, 2023 (GLOBE NEWSWIRE) -- Minera IRL Limited (“Minera”, the “Company” or “we”) (BVL:MIRL) (CSE:MIRL) (FWB:DZX) (OTCQB:MRLLF) is pleased to report assay results from the final set of drill holes completed as part of Phase 1 of the Two-Phase Long-Hole (“LH”) Drilling Campaign currently underway at the Corihuarmi Gold Mine (“Corihuarmi”) located in central Peru.

Highlights of the Phase 1 final drill holes include:

• TLS23-52, 25.00 m of oxides from 10.00 m depth assaying 0.599 grams Au per tonne (“g/t Au”).
• TLSU23-18, zero to 20.00 m depth of oxides assaying 0.536 g/t Au.
• TLSU23-01, zero to 3.00 m depth of oxides assaying 0.508 g/t Au.
• TLS23-36, 15.00 m of oxides from 10.00 m depth assaying 0.504 g/t Au.
• TLAD23-30, 25.00 m of oxides from 10.00 m depth assaying 0.364 g/t Au.
  

Gold mineralization at Corihuarmi is mined by open pit methods. The average grade of the mineralized material placed on the leach pads between January and June 2023 was 0.193 g/t Au.

About Phase 1 of the LH Drilling Campaign

The LH Drilling Campaign was started in November 2022 aiming to provide additional data to supplement the database generated from the Diamond Drill Program executed in the second half of 2022. Both drilling initiatives are in line with the Company’s goal to confirm the continuity of gold mineralization at Corihuarmi, and to produce a new Mineral Resource Estimate in accordance with Canadian National Instrument 43-101.

Phase I of the LH Drilling Campaign initially comprised 53 drill holes completed between November 2022 and March 2023. The results were previously announced in the press release dated April 12, 2023, and titled “Minera IRL Announces Initial Results of the Ongoing Long-Hole Drilling Campaign at the Corihuarmi Gold Mine.” This release also included the announcement of an extension to Phase I based on the analysis of results by the Company’s technical teams. Said extension consisted of 103 additional drill holes within the pits that are currently mined at Corihuarmi, totaling 3,569 metres drilled.

To date, a total of 156 drill holes measuring 5,422 metres have been completed, sampled, and assayed as part of Phase I of the LH Drilling Campaign. Principal intercepts of the final set of drill holes are summarized as follows:

Phase II of the LH Drilling Campaign commenced in the last week of June 2023 and encompasses 100 drill holes, totaling over 3,400 metres. These drill holes are anticipated to be completed over a span of three months, with a focus on the Cayhua, Susan and Diana Pits. Additionally, the campaign will cover new mining areas, namely North Cayhua and Scree Slope Extension. The Company intends to publish more results as the drilling campaign progresses.
