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 1,165,800 ounces Au Eq Measured and Indicated and 341,300 ounces Au Eq Inferred (See press release dated August 28, 2015). 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.
  • 100%-owned high-grade, flagship Goliath Gold Project demonstrating an indicated and inferred resource of 1,165,800 ounces Au Eq Measured and Indicated and 341,300 ounces Au Eq Inferred (see press releases)
  • Results of drilling programs have defined high-grade near-surface intersections, indicating significant upside potential for both resource and project economics
  • Low initial start-up CAPEX of $133M with cash-flows from open-pit production funding underground development and mine expansion. The optimized mining plan used in the 2017 PEA envisions underground production that begins in the second year with the open pit operating over an additional 7 years at a reduced output to supplement underground production to a total of 2,500 tonnes per day over the course of a 13 year total mine life. Total gold production is estimated at 1.14 million ounces of gold and 2.0 million ounces of silver. Initial capital to fund construction is estimated at C$133.2 million with an additional C$132.5 million in sustaining capital over the LOM primarily to fund the underground expansion
  • 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

After-tax NPV5%
Annual Production (Ounces)
87,850 Au
With peak production
exceeding 100,000 oz per
year Au from years 3 to 6
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 130,000 metres of diamond core drilling since 2008 (in addition to Teck Resources' historical drilling).

Notes from Resource Estimate:
  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 quantity and grade of reported Inferred resources in this estimation are uncertain in nature and there has been insufficient exploration to define these Inferred resources as an Indicated or Measured mineral resource and it is uncertain if further exploration will result in upgrading them to an Indicated or Measured mineral resource category.
  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$1,397/oz and silver price of US$22.93/oz based on the April 30, 2015 three year trailing average prices and an exchange rate of US$1.06=Cdn$1.00 were utilized in the AuEq cut-off grade calculations of 0.35 g/t AuEq for Open Pit and 1.90 g/t AuEq for Underground mineral resources.
  5. Open Pit mining costs were assumed at Cdn$5.00/t for mineralized material, Cdn$3.15/t for waste rock and Cdn$2.00/t for overburden, while Underground mining costs were assumed at Cdn$70.00/t, with process costs of Cdn$13.81/t, G&A of Cdn$2.72/t, and process recoveries of 95% for gold and 70% for silver.
  6. The Au:Ag ratio used for AuEq was 82.68.
  7. A bulk density model averaged 2.76 t/m3 for mineralized material.
  8. Totals in the table may not sum due to rounding.
