Justin Reid, CEO of Troilus Gold, commented “The entire Troilus team is pleased to present the results of our PEA, clearly demonstrating the potential for our project to become a major contributor as a large North American gold producer. The PEA supports: a project with production spanning 22 years, robust potential economics at discounted and current gold prices, low CAPEX, low capital intensity, and a rapid payback. The first 14 years will target production in excess of 246,000 ounces gold per year peaking at in excess of 300,000 ounces in Year 5. The Troilus Geological team has demonstrated the ability to identify an abundance of untested targets and has a track record of adding significant ounces over a very short period of time. We believe the Troilus property has the potential to extend the mine life beyond the projected 22 years presented in the PEA and provide the opportunity to expand the scale in the future by continuing to seek increases to the mineral resource estimate with ongoing exploration and drilling. Our goal is to make this a cornerstone mining Project within both the Quebec and Canadian Gold landscapes.”

“We believe the Project provides a strong foundation for building and growing the company in a mining friendly jurisdiction. With a strong treasury to support next steps, we will now be commencing pre-feasibility work and working towards finalization of an Environmental Impact Study for the Project while continuing to explore the geological potential of the 107,000-hectare Troilus property. We look forward to working with our partners in the Eeyou Istchee James Bay region including the Cree Nation of Mistissini, the Cree Nation Government, the local communities of Chibougamau and Chapais, and with the support of the Quebec and federal governments, to advance the Troilus Project.”

Financial Analysis

At a Base Case US$1,475 per ounce gold price and a US$:C$ exchange of $0.74, the Project generates an after-tax Net Present Value (NPV) of US$576M, at a 5% discount rate and an Internal Rate of Return (“IRR”) of 22.9%. Payback on initial capital is 4 years. Before taxes, NPV at a 5% discount rate is US$971M, IRR is 29.6% and payback is 3.7 years.

Table 1: Summary of Troilus Gold Economic Results by Gold Price (US$)

The Project generates cumulative cash flow of US$1.27 billion on a post-tax basis and US$2.04 billion pre-tax, at a Base Case of US$1,475 per ounce gold price based on a throughput of 35,000 tpd over 22 years. The PEA assumes an open pit operation for the first fourteen years with the underground operation coming online starting in year 8.

The PEA is preliminary in nature, includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the PEA will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability.

Capital and Operating Costs
The PEA capital and operating cost estimates for the Troilus Gold Project are summarized below. The Initial CAPEX (net of existing infrastructure) is US$333 million and Sustaining CAPEX over the life of the mine is an additional US$506 million. The underground mine will require US$240 million of underground development CAPEX in years 6 to 8 and US$175 million in sustaining capital to maintain the underground operation. The underground will start development with first mill feed projected to come online in Year 8. All in Sustaining Cost (“AISC”) is US$1,051 per ounce Au.

Mining

The PEA considers an initial open pit mining using a 100% owner operated equipment fleet including 28- 181 tonne trucks, electric hydraulic shovels, wheel loaders and drills. The open pit will overlap mill feed production with the underground mine starting in year 8. The open pit will be complete in Year 14 and the underground mine will continue production until Year 22. The mine has been designed to deliver an initial 12.6 million tonnes per year (35,000 tonnes per day) of mill feed. The PEA contemplates a mine that will extract mill feed over a 22‑year period not including 12 months of pre-production stripping. The PEA delivers 192.5 million tonnes with average head grades of 0.71 gpt gold, 0.08% copper and 0.97 gpt silver. The process plant is expected to have three months of commissioning in the first year of production.

The project will mine three areas: 87 Zone, J Zone and the new Southwest (SW) Zone. The 87 Zone will have a single-phase open pit followed by underground mining. The J Zone has been designed with 3 phases of open pit only for this study. The SW Zone design is comprised of 2 open pit phases. Mining commences in the 87 Zone pit and SW Zone pit areas in the pre-production period. The J Zone pit area starts production in Year 2. The 87 Zone pit will be complete in Year 6 and the underground mine will continue beneath the open pit from that point onwards. The SW Zone pit will be finished in Year 12. The J Zone pit will finish in Year 14. Underground mining finishes in Year 22. Waste from the open pits will be backfilled in the 87 Zone pit once open pit mining is complete. This provides fill for the underground and short waste haulage for the J Zone pit phases, reducing the overall size of the waste storage facilities.

The average strip ratio for the open pit life of the mine is estimated at 3.9:1. Material movement averages 71 million tonnes (feed and waste) in the first 5 years with the peak at 74 million tonnes in Year 1. The open pit will provide 150.1 million tonnes of feed to the process plant for the first 14 years of the project. Open pit bench heights of 10 metres will be mined and ore hauled with 181-tonne haul trucks and matching loading equipment including electric hydraulic shovels. The open pit mining fleet will be leased. Best practice grade control drilling will be done with reverse circulation drilling and rock sampling on mine benches prior to blasting. This provides the greatest flexibility for grade control during operations while maintaining reasonable mine operating costs and production capability.

Underground mine development will commence in Year 6 and first mill feed to the plant from underground occurs in Year 8. The underground mine will be located beneath the 87 Zone pit and utilize sub-level caving along the edges of the open pit and slot and mass blast in the lower levels. The portal is located adjacent to the primary crusher. Mill feed material and waste will be brought to the surface initially with trucks but will transition to the RailVeyor system for the life of the mine. The underground mine will ramp up production from its initial levels to 9,000 tpd by Year 9 and maintain that rate until the end of the mine life.

During the mining operation a stockpile will be maintained adjacent to the primary crushing plant to be used as supplemental feed as required to meet production targets, weather events and as mill feed in the later years of the operation. Waste rock will be hauled to dedicated waste management facilities near the open pits, backfilled into the 87 Zone pit and also used for lifts of the tailings management facility. Concurrent reclamation of the waste management facilities is planned.

Metallurgy

Initial test work was completed by COREM and Kappes Cassidy as well the historical operating data, to develop the flow sheet. The process plant consists of primary crushing, SAG and ball milling with gravity gold concentration, copper flotation, concentrate filtration and tailings thickening and disposal. Copper concentrate, enriched with gold, will then be sent to a smelter for refining. Gold recovery is estimated to be 90%, with 30% produced onsite as gravity concentrate and the balance contained in the final copper concentrate. Copper recovery is expected to be 90%.

Infrastructure

The Troilus Gold Project is located in Quebec, approximately 120 kilometres north of Chibougamau, where Inmet Mining Corp. operated a large mine/concentrator complex from 1996 – 2010. Access to the mine site from Chibougamau is by the Route du Nord.

The Troilus project benefits greatly from the upgraded, and substantial infrastructure on site including:

• Power line and 50MW substation sufficient for project power requirements,
• All weather access road,
• Tailings facility and water treatment plant,
• Camp facilities,
• Site roads,
• Water supply,
• Septic system.

The existing tailings management facility has the capacity to accommodate the life of mine production as described in this PEA. As part of the design it is proposed to develop the tailings dam into a centreline constructed containment from the existing upstream designed containment. The building of this containment wall will utilise waste rock from the mine operations.

A NI 43-101 technical report supporting the PEA to be prepared by AGP will be posted on Troilus Gold’s website at www.troilusgold.com and on SEDAR at www.sedar.com, within 45 days following this news release.

Mineral Resources Estimate
The total estimated indicated Mineral Resource Estimate upon which the PEA is based includes 4.96 Moz AuEq (177 Mt with an average grade of 0.87 g/t AuEq) and a total inferred Mineral Resource Estimate of 3.15 Moz AuEq (116.7 Mt with an average grade of 0.84 g/t AuEq).

Table 4 - Mineral Resource Estimate – Effective as of July 20, 2020

Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability; Summation errors may occur due to rounding; Open pit mineral resources are reported within an optimized constraining shells.

Open pit cut-off grade is 0.3 gpt AuEQ where the metal equivalents were calculated as follows:

• Z87 Zone: AuEq = Au grade + 1.2566 * Cu grade + 0.0103 * Ag grade
• J4/J5 Zone: AuEq = Au grade + 1.2979 * Cu grade + 0.0108 * Ag grade
• SW Zone: AuEq = Au grade + 1.2768 * Cu grade + 0.0106 * Ag grade

Metal prices for the AuEQ formulas are: $US 1,600/ oz Au; $3.25/lb Cu, and $20.00/ oz Ag; with an exchange rate of US$1.00:CAD$1.30;
Metal recoveries for the AuEQ formulas are:

• Z87 Zone: 83% for Au recovery, 92% for Cu recovery and 76% for Ag recovery
• J4/J5 Zone: 82% for Au recovery, 88% for Cu recovery and 76% for Ag recovery
• SW Zone: 82.5% for Au recovery, 90% for Cu recovery and 76% for Ag recovery

The resource constraining shells were generated with:

• Metal Prices: Gold $US 1600/oz, Copper $US 3.25/lb, Silver $US 20/oz
• Mining Costs:
  o J Zone and 87 Zone base cost $Cdn 1.71/t moved,
  o SW Zone base cost $Cdn 1.66/t moved
  o Incremental cost $Cdn 0.03/t waste moved, $Cdn 0.02/t feed moved
• Process and G&A Costs: $Cdn 8.44/t processed
• Wall slopes: varied between 49.5 to 60 degrees depending on pit area and slope sector
• Metal Recoveries:
  o Gold: 90% all zones except in lower grade (Au<1/2 g/t) portions of SW zone = 88%
  o Copper: 90% all zones except in higher grade (Cu%>0.13%) portions of SW zone = 92%
  o Silver: all zones 40%

Underground cut-off grade is 0.9 AuEQ at Z87 Zone and J4/J5 Zone

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

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.
