Goliath Gold Project

Treasury Metals (TSX: TML) is a Canadian gold exploration and development company focused on its 100% owned high-grade Goliath Gold Project, which currently demonstrates 1,229,800 ounces Au Eq Measured and Indicated and 226,700 ounces Au Eq Inferred (See press release dated October 16, 2018). The Project, which is located in the Kenora/Dryden district in northwestern Ontario, is slated for near-term Canadian gold production.

Treasury Metals is advancing through the Canadian permitting process to begin production at its open-pit gold mine and up to 2,500 tpd processing facility in the near future. Subsequent underground operations will be developed in the latter years of mine life and will be funded from the project's initial cash flow.

Location: 20 km east of Dryden, Northwestern Ontario
Resource: 1,229,800 ounces Au Eq Measured and Indicated and 226,700 ounces Au Eq Inferred
Host to: Gold, Silver
Stage: Advancing to bankable feasibility study
Infrastructure: Mining-related Infrastructure & skilled local workforce readily available. Premier Ontario Gold Developer: Stable, mining-friendly jurisdiction of Northwestern Ontario. Strong leadership team with successful capital markets, mine and operations expertise.

Treasury Metals announced an updated preliminary economic assessment on its Goliath Project on March 8, 2017. Key Highlights include:
  • After-tax NPV 5% of $306M and 25% IRR
  • Producing an average of 87,850 oz Au and 160,000 Ag annually over 13 years of mine life
  • Payback Period of 4.1 years
  • Low initial start-up CAPEX of $133M
  • LOM average feed grade of 3.81 g/t Au and 10.55 g/t Ag

LOM Average Feed Grade
3.81 g/t Au

The preliminary economic assessment is preliminary in nature and 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 preliminary economic assessment will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability.

Treasury Metals has completed more than 170,000 metres of diamond core drilling since 2008 (in addition to Teck Resources' historical drilling).

  1. Mineral Resources which are not Mineral Reserves do not have demonstrated economic viability. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.
  2. The Inferred Mineral Resource in this estimate has a lower level of confidence than that applied to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of the Inferred Mineral Resource could be upgraded to an Indicated Mineral Resource with continued exploration.
  3. The Mineral Resources in this press release were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the CIM Standing Committee on Reserve Definitions and adopted by the CIM Council.
  4. A gold price of US$1,250/oz and silver price of US$17.00/oz based on the July 31, 2018 approximate three year trailing average prices and an exchange rate of US$0.80=Cdn$1.00 were utilized in the AuEq cut-off grade calculations of 0.40 g/t AuEq for Pit Constrained (> 170 metres elevation above sea level or < 239 metres depth from surface) and 1.90 g/t AuEq for Underground mineral resources.
  5. Open Pit mining costs were assumed at Cdn$3.45/t for mineralized material, Cdn$3.30/t for waste rock and Cdn$2.00/t for overburden, while Underground mining costs were assumed at Cdn$78.00/t, with process costs of Cdn$18.15/t, G&A of Cdn$2.86/t, and process recoveries of 95.5% for gold and 62.6% for silver.
  6. The Au:Ag ratio used for AuEq was 1:112.17.
  7. A bulk density model averaged 2.76 t/m3 for mineralized material.
  8. Totals in the table may not sum due to rounding.
