Treasury Metals Announces 1.2 Million Ounces Gold Equivalent Measured & Indicated Mineral Resource Estimate with Gold Grade Increase
October 16, 2018 - TORONTO – Treasury Metals Inc. (TSX: TML) (“Treasury Metals” or the “Company” - https://www.commodity-tv.net/c/search_adv/?v=298263) is pleased to provide an updated National Instrument 43-101 Mineral Resource Estimate (the “2018 Mineral Resource Estimate”) on its 100% owned Goliath Gold Project. The Mineral Resource Estimate was completed by independent firm P&E Mining Consultants Inc. (“P&E”).
The 2018 Mineral Resource Estimate is an update to the NI 43-101 Mineral Resource Estimate previously released on August 28, 2015 (the “2015 Mineral Resource Estimate”) and includes results from a database representing an additional 98 diamond drill holes totaling 41,500 m of infill drilling completed between 2016 and 2018.
- Successful conversion program:
- Total Measured and Indicated Mineral Resources are now 1,229,800 gold equivalent (“AuEq”) ounces (16.20 Mt at 2.36 g/t AuEq). See Figure 1 Main Zone Longitudinal Projection.
- Measured and Indicated Underground AuEq Ounces increased by 64% from the 2015 Mineral Resource Estimate:
- Totaling 640,100 AuEq ounces with an average grade of 5.54 g/tonne AuEq (5.39 g/t Au);
- Open Pit Mineral Resource shell optimized further to contain less waste and could lead to an improved strip ratio.
- A portion of the increase can be attributed to redefining the boundary between the Underground and Open Pit Mineral Resources resulting in a higher portion of AuEq ounces reported within the Underground Mineral Resource capturing the high grade ounces.
- Gold Equivalent Grade increase for combined Measured and Indicated Mineral Resources
- In-Pit: +9.0 % (1.45 g/tonne AuEq);
- Out of Pit: +8.0 % (5.54 g/tonne AuEq);
- Total: +34.1 % (2.36 g/tonne AuEq).
- Silver Grade increase in Measured and Indicated Mineral Resources
- Mineral Resources at Goliath remain open at depth and has exploration potential for additional mineralized shoots along strike.
Treasury’s primary goal for the diamond drill programs has been to increase Mineral Resource confidence and convert AuEq ounces from Inferred to Measured and Indicated Mineral Resource classifications to be included in future engineering studies. These programs were highly successful with a significant upgrade of AuEq ounces to higher confidence classifications and grade improvements both in the open pit and underground Mineral Resource Estimates. A secondary drilling goal of Mineral Resource expansion successfully extended the Deposit east of the Main Zone high-grade mineralized shoots, and continued to demonstrate opportunities for Mineral Resources that could add to future mine plans.
The following table summarizes the NI 43-101 Mineral Resource Estimate in the Measured, Indicated and Inferred Mineral Resource classifications:

- 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.
- 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.
- 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.
- 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 <230 metres depth from surface) and 1.90 g/t AuEq for Out of Pit Mineral Resources.
- 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.
- The Au:Ag ratio used for AuEq was 1:112.17
- A bulk density model averaged 2.76 t/m3 for mineralized material.
- Totals in the table may not sum due to rounding.
“We are pleased with the success we’ve had in converting Inferred Mineral Resource AuEq ounces to the Indicated Mineral Resource classification. Our future programs will now focus on growth through exploration, and particularly the expansion of higher grade Mineral Resource both at depth and along strike within the developing C Zone shoots. Our ongoing project optimization work has identified opportunities to significantly improve the Mineral Resource grade of the Main Zone by using a higher grade cut-off, and still maintain the majority of the contained AuEq ounces. This analysis shows higher mineral resource grades, continuity at the higher cut-off grades and the potential to expand the mineral resource at depth. Further work will be done to investigate this opportunity.” stated Treasury Metals Interim CEO Greg Ferron.
