Minera IRL Announces Initial Results of the Ongoing Long-Hole Drilling Campaign at the Corihuarmi Gold Mine
Minera IRL Limited (OTCQB:MRLLF) has announced the assay results from its Two-Phase Long-Hole Drilling Campaign at the Corihuarmi Gold Mine in Peru, initiated in November 2022. Initial results from the campaign reveal promising gold grades, including 20 meters at 0.65 g/t Au from a depth of 5 meters. A total of 53 drill holes, totaling 1,853 meters, were completed, leading to a decision to extend the campaign with an additional 100 drill holes over 3,483 meters. The company aims to confirm the continuity of gold mineralization to support future operations and update its Mineral Resource Estimate. In 2022, the average grade of gold mined was 0.21 g/t Au, with a total of 20,938 ounces of gold shipped, indicating ongoing production capacity at Corihuarmi.
- Initial drill results show significant gold grades, with LHS23-36 reporting 20.00 m at 0.65 g/t Au.
- Decision to extend Phase I of the drilling campaign by adding 100 drill holes, indicating potential for increased resource estimation.
- The average grade of gold from the leach pads in 2022 was 0.21 g/t Au, reflecting stable production.
- None.
LIMA, Peru, April 12, 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 first set of drill holes completed as part of the Two-Phase Long-Hole (“LH”) Drilling Campaign started in late November 2022 at the Company’s producing Corihuarmi Gold Mine (“Corihuarmi”) located in central Peru.
Highlights of the initial drill holes include:
- LHS23-36, 20.00 m of oxides from 5.00 m depth assaying 0.65 grams Au per tonne (“g/t Au”).
- LHS23-35, 14.00 m of oxides from 6.00 m depth assaying 0.45 g/t Au.
- LHSS23-53, zero to 4.00 m depth of oxides assaying 0.41 g/t Au.
- LHAD23-24, 11.00 m of oxides from 24.00 m depth assaying 0.39 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 December 2022 was 0.21 g/t Au, with 20,938 ounces of gold shipped during 2022.
About the LH Drilling Campaign
As previously announced in the Company’s December 14, 2022 press release titled “Minera IRL Completes Diamond Drill Program at the Corihuarmi Gold Mine and Begins a New Two-Phase Drilling Campaign,” the LH Drilling Campaign was aimed to provide additional data to supplement the database generated from the Diamond Drill Program executed between July and November 2022. The objectives and execution of both drilling initiatives are in line with the Company’s goal to confirm the continuity of gold mineralization at Corihuarmi to ensure future operations and to update its most recent Mineral Resource Estimate.
The LH Drilling Campaign targeted specific areas reported to contain coarse gold mineralization with grades in the range of 0.13 g/t Au to 0.24 g/t Au. Ongoing in-house analysis supports the viability of using this material to achieve an optimized blend at the leach pads in an effort to improve gold recoveries.
A total of 53 drill holes measuring 1,853 metres have been completed, sampled, and assayed between November 2022 and March 2023, as part of Phase I of the LH Drilling Campaign. Principal intercepts are summarized as follows:

The review and assessment of the assay results by our technical teams has triggered the decision to extend Phase I of the LH Drilling Campaign and execute 100 additional drill holes within Cayhua, Susan and Diana Pits totaling 3,483 metres. These additional drill holes are expected to be completed over a period of four months. The Company plans to release further results as the drilling campaign advances, along with the proposed start date and execution of Phase II, anticipated towards the second half of 2023.
