Troilus Gold Corp. is pleased to provide an updated mineral resource estimate from Troilus property in northwestern Quebec, Canada.
Troilus Gold Corp. (TSX:TLG, OTCQB:CHXMF) (“Troilus” or the “Company”) is pleased to provide an updated mineral resource estimate (see Table 1) from its 100% owned Troilus property located 170 km by road north of Chibougamau, in northwestern Quebec, Canada (the “Troilus Project”). The updated mineral resource estimate is summarized in Table 1.
Highlights:
- The pit constrained estimated mineral resources in the indicated mineral resource category have increased by 910,000 ounces AuEq, with J Zone (J4 and J5) having increased by 69%, from the 2018 mineral resource estimate (which had an effective date of November 19, 2018)
- The total estimated indicated mineral resource has increased to 4.71Moz AuEq and the total estimated inferred mineral resource has increased to 1.76Moz AuEq
- Total estimated indicated mineral resources have increased by 129% since the 2017 mineral resource estimate (which had an effective date of June 30, 2016) when the Troilus Project was acquired and 20% since the 2018 mineral resource estimate
- Underground tonnage decreased by 24% while underground grade in the indicated mineral resource category has improved from 1.50 g/t AuEq to 1.86 g/t AuEq from the 2018 mineral resource estimate.
Table 1 – Mineral Resource Estimate– Effective as of October 31, 2019
This updated mineral resource estimate, prepared in accordance with Canadian Institute of Mining, Metallurgy and Petroleum “CIM” (2014) Definition Standards incorporated by reference in National Instrument 43-101 Standards of Disclosure for Mineral Projects (“NI 43-101”), is the result of over 36,000 metres (81 drill holes) of drilling completed by the Company from February 2019 to July 2019 in addition to the 36,000 metres (91 drill holes) of drilling completed in August 2018. The mineral resource estimates for Z87 Zone are based on a combined pit constrained and underground mining scenario, while the mineral resource estimates for the J Zone (J4 and J5) are based on pit constrained mining (see Figure 1 for Plan View of Mineralized Zones). The combined updated pit constrained and underground mineral resource estimate is summarized in Table 2.

“In just two years of drill programs since acquiring the Troilus Project, we have outlined what we believe to be a promising development asset in Quebec and believe there is still room for further growth,” said Justin Reid, CEO of Troilus. “Our investors will continue to benefit from our low discovery costs, technical expertise and support from our local communities. The careful work and scientific analysis by our technical team has resulted in a substantial increase to the Troilus estimated mineral resources which provides the foundation for ongoing exploration and development of this exciting property.”
“This year’s drilling results provide further confirmation that mineralization at the Troilus Project extends beyond the boundaries of the historic pits. The most significant contribution to the updated mineral resource estimate comes from the J Zone (J4 & J5) where the pit constrained potential has increased substantially. This development was a key objective at the outset of this years’ drill program,” commented Blake Hylands, SVP Exploration. “We expect the results of our planned 2020 program will show additional growth potential of an already significant mineral resource estimate, and we will draw on our enhanced geological understanding to further explore the belt”
The updated mineral resource estimate was completed in accordance with the “CIM”(2014) Definition Standards incorporated by reference in NI 43-101 by Roscoe Postle and Associates (“RPA”) 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.
2019 Drill Program
In the J Zone (J4 & J5), the 2019 drill program was primarily designed to expand near-surface mineralization to support an open-pit mine development scenario, while improving the geological understanding of the main mineral trend and identifying future growth opportunities. In the Z87 South Zone, the 2019 drill program was designed to follow-up on the positive holes drilled in this zone in 2018, while increasing drill resolution and improving the geological understanding of the main mineral trend on the property.
Z87 Zone
Mineralization at the Z87 Zone is hosted in breccias and amphibolite grade metamorphic rocks within a much broader, 4.5 kilometre by 400 metre, metamorphosed diorite, known as the Troilus Diorite. Fine-grained disseminated gold accounts for approximately 90% of mineralization at Troilus, primarily as native gold and electrum with grains as large as 20 microns. Chalcopyrite, pyrite, and pyrrhotite are broadly disseminated throughout the mineralized body, which are rarely associated with gold (<1-3%). Vein-hosted gold accounts for approximately 10% of mineralization which are responsible for high grade intercepts (>50 gpt over 1 m) at Troilus. The broad geology and style of mineralization at the Z87 Zone creates a large deposit area, nearly 1 kilometre along strike and 30-50 metres wide, which remains open both along strike and down dip.
J Zone (J4 and J5)
The mineral bodies in the J Zone are hosted in the northern continuity of the Troilus Diorite and, similarly to what is observed in the main Z87 Zone and Z87 South Zone, are elongated parallel to a penetrative NE-trending foliation, moderately to steeply dipping to the north west. From top to bottom, the sequence comprises (i) a volcaniclastic unit, occurring along the hanging wall of the mineralization, and composed of well laminated intermediate to felsic rocks, locally mineralized, with semi-massive sulfide occurrences; and (ii) a thick metadioritic unit, comprising fine to coarse grained diorites, locally brecciated, commonly crosscut by decimetric to metric felsic dikes, which mostly occur concentrated in the upper parts of the sequence, in the immediate hanging wall of the mineralized intervals. Towards the bottom of the sequence, in the footwall, typical diorite breccias are present, displaying an intense silicification and being locally importantly mineralized. The main mineralized intervals in the J Zone are characterized by sulfide stringers and fine sulfide disseminations along the foliation occurring within a very fine grained biotite-rich and silicified diorite. Pyrite is the main sulfide, and it is intrinsically associated with gold mineralization.

Quality Assurance and Quality Control
During the 2019 drill program, one metre assay samples were taken from NQ core and sawed in half. One-half was sent for assaying at ALS Laboratory, a certified commercial laboratory, and the other half was retained for results, cross checks and future reference. This protocol was used for holes TLG-J419-091 to 106. 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 quality assurance/quality control (QA/QC) samples, a 50 g fire assay was done. In addition to gold, ALS laboratory carried out multi-element analysis by AA, 33 elements. The QA/QC program included insertion of one certified mineralized standard and one blank sample in each batch of 25 samples. For the main mineralized zone, two metre assay samples were taken from NQ core and sawed in half. During the campaign, a decision was made to use two metres half NQ core and apply the metallic sieve protocol for all core samples. The gold analyses were by metallic sieve. A fine crushing 70% <2mm was performed. The sample was divided so that 1.2 to 1.5 kg was used for analysis. The sample of 1.2 to 1.5 kg was then 95% pulverized to <106 mesh. 50 g was recovered for ME-ICP61 analysis of 33 elements four acid ICP-AES. The remainder of the sample was sent to the screen to divide the fraction larger and smaller than 106 mesh. The portion smaller than 106 mesh was analyzed in 50 g by Fire Assay. The portion larger than 106 mesh was fully analyzed. The values were then combined by weighted calculation. Both type of results were transmitted to Troilus by a certificate certified by the laboratory.

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.
