Minera IRL announces receipt of New Technical Report and increase reserves of Corihuarmi Gold Mine

LIMA, PERU--(Marketwired - Oct. 2, 2017) - Minera IRL Limited ('Minera IRL' or the 'Company') (BVLAC:MIRL)(CSE:MIRL)(CNSX.MIRL)(CSE.MIRL.CN) is pleased to announce receipt of a National Instrument 43-101 compliant technical report for its Corihuarmi gold mine that reflects an increase in estimated gold reserves at its open pit Corihuarmi gold mine for a total of 98,928 ounces of gold and an extension of the life of mine ("LOM") through December, 2020. The reserves estimated are located in the lowest part of the productive seven small open pits, mainly in the areas of Diana Extension, Susan and Cayhua.

The technical report was prepared by Andean Consulting Group SAC and includes information from the Company's 2016 drilling campaign, which consisted of 56 diamond drill holes (5074.30 m) and 29 RC drill holes (2,199.00m).

An exploration drilling program is expected for the second half of 2018 to extend additional resources. Corihuarmi has licensed 9,000ha of mining concessions.

Minera IRL Limited Executive Chairman, Gerardo Perez comments, "We are pleased with the results of our reserves. It is encouraging that we now have enough reserves to produce at least till late 2020 and we believe that further drilling in 2018 will continue to extend the LOM."

Gold production is projected over 24,000 ounces for 2017, an average of 21,000 ounces per annum for the 3 year period through 2020. The Corihuarmi Gold Mine started production in March 2008 and up toMarch 2017 it has produced 280,184.46 ounces of gold.

The Company renewed its dump truck fleet (10 trucks) in the Corihuarmi mine through a $1.5 million lease, reducing operating costs and ensuring efficiency, safety and environmental care in the transportation of ore. The Corihuarmi mine continues to meet its environmental commitments and Minera IRL continues to enjoy the favorable opinion of the local communities through its social development programs.

Quality Assurance - Quality Control ("QA/QC")

Thorough QA/QC protocols are followed on the Corihuarmi mine including insertion of duplicate, blank and standard samples in all drill holes. The half-core samples are submitted directly to Certimin Laboratories, Lima, Peru for preparation and Analysis. Analysis is conducted on 50 g aliquots. Analysis of Au is performed using fire assay method with atomic absorption (AA). Certimin has been servicing the Peruvian mining industry for 21 years. It participates in international proficiency testing programs such as CANMET and GEOSTATS, and develops its services with the support of the Integrated Management System for the compliance of regulatory requirements such as ISO 9001, ISO /IEC 17025, ISO 14001, and OHSAS 18001. Eng. Andrés Rivera has reviewed the QA/QC results for the 5,753.00 samples coming from of two drilling programs and considers that they adequately demonstrate the Certimin assay reliability.
