“The Troilus Team is incredibly pleased with the results of the new resource. We have materially added to the estimated inferred and indicated resource in every zone while maintaining essentially the same grade. In addition, we have discovered and added a new impactful inferred mineral resource in the Southwest Zone that we believe still has the ability to grow materially through further drilling. Troilus has shown scale, the ability for expansion and optionality from multiple resource centers” said Justin Reid, CEO of Troilus. “Since acquiring the Troilus project in 2017, the careful work and scientific analysis by our technical team has resulted in a 142% increase to the indicated mineral resource estimate and a 350% increase to the inferred mineral resource estimate, providing the foundation for a Preliminary Economic Assessment for the project which we are targeting for release towards the end of calendar Q3.”

“Troilus continues to expand,” commented Blake Hylands, SVP Exploration. “We are very pleased to observe that as the mineral resource estimate continues to grow, the grade remains consistent and the new Southwest Zone is comparable to what we have observed at Z87 and the J Zones. Looking ahead to a 20,000 metre drill program planned for later this year, we intend to continue drilling in the Southwest Zone to further tap into this new area of mineralization as we believe there is still significant room for further growth and we will complete infill drilling around the main ore bodies at Z87 and J Zones.”

The updated mineral resource estimate was completed by AGP Mining Consultants Inc. (AGP) and has been reviewed internally by the Company. The full technical report in respect of the updated mineral resource estimate (the “Technical Report”) will be available on SEDAR (www.sedar.com) under the Company’s issuer profile within 45 calendar days.

Quality Assurance and Quality Control

During the Southwest Zone drill program in 2019/20, one metre assay samples were taken from NQ core and sawed in half. One-half was sent for assaying at ALS Canada Ltd. (“ALS”), a certified commercial laboratory, and the other half was retained for results, cross checks, and future reference. A strict QA/QC program was applied to all samples; which included insertion of one certified mineralized standard and one blank sample in each batch of 25 samples. Every sample was processed with standard crushing to 85% passing 75 microns on 500 g splits. Samples were assayed by one-AT (30 g) fire assay with an AA finish and if results were higher than 3.5 g/t Au, assays were redone with a gravimetric finish. For QA/QC samples, a 50 g fire assay was done. In addition to gold, ALS carried out multi-element analysis for ME-ICP61 analysis of 33 elements four acid ICP-AES.

Cautionary Note to U.S. Investors Concerning Estimates of Mineral Resources

These mineral resource estimates have been prepared in accordance with the requirements of Canadian securities laws, which differ from the requirements of U.S. securities laws. The terms “mineral resource”, “measured mineral resource”, “indicated mineral resource” and “inferred mineral resource” are defined in NI 43-101 and recognized by Canadian securities laws but are not defined terms or recognized under U.S. securities laws. U.S. investors are cautioned not to assume that any part or all of mineral deposits in these categories will ever be upgraded to mineral reserves. “Inferred mineral resources” have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an “inferred mineral resource” will ever be upgraded to a higher category. Under Canadian securities laws, estimates of “inferred mineral resources” may not form the basis of feasibility or pre-feasibility studies. U.S. investors are cautioned not to assume that all or any part of an inferred mineral resource exists or is economically or legally mineable. Accordingly, these mineral resource estimates and related information may not be comparable to similar information made public by U.S. companies subject to the reporting and disclosure requirements under the U.S. federal securities laws and the rules and regulations thereunder.
