Deer Horn Reports Positive Preliminary Economic Assessment at its Deer Horn Gold-Silver-Tellurium Project in British Columbia
PEA indicates a 9-year open-pit mine life with average grades of 3.73 g/t gold, 117.1 g/t silver and 118 ppm tellurium with a 1.6-year payback.
Vancouver, BC, Canada, June 6, 2018 – Deer Horn Capital Inc. (CSE: DHC, OTCBB: GODYF) (the “Company” or “Deer Horn”), reports positive results from an independent Preliminary Economic Assessment (“PEA”) at its Deer Horn gold-silver-tellurium polymetallic property in north-central British Columbia. The full PEA, which was prepared in accordance with National Instrument 43-101 regulations, is available for viewing on the Company’s website at www.deerhorncapital.ca and in its disclosure record at www.SEDAR.com.
PEA Highlights (values shown in $CDN unless indicated otherwise)
- Pre-tax NPV (5%) of $56.6 million and internal rate of return of 56%;
- After-tax NPV (5%) of $36.5 million and internal rate of return of 42%;
- Initial Capital of $28.3 million;
- After-tax payback of initial capital in 1.6 years;
- Life of Mine (LOM) production of
- 73,000 Ounces Gold
- 2,100,000 Ounces Silver
- 67,000 kilograms Tellurium
- 1,700,000 pounds Copper
- 3,600,000 pounds Zinc
The PEA figures were calculated using metals prices of US$1,300 per ounce for gold, US$17 per ounce for silver, US$100 per kilogram for tellurium, US$3.00 per pound for copper and US$1.00 per pound for zinc. The Preliminary Economic Assessment is preliminary in nature. It 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.
Deer Horn plans to operate the project as a high-grade “small mine” under the British Columbia Mines Act. This designation simplifies and expedites the permitting process with considerably lower up-front costs.
“We’ve engineered Deer Horn for low capital costs and rapid payback in a well-established mining jurisdiction,” said Deer Horn CEO and President Tyrone Docherty. “Our strategy is to put the project into production quickly and establish its viability initially on a small scale. Since the PEA was calculated on only 450 meters of a 2.4-kilometer-long mineralized system, we believe we can explore and expand the operation over time using mining cash flow and exploit the knowledge of the system that we gain as we mine.”
The PEA recommended infill and tightly-spaced step-out diamond drilling focused both on upgrading and expanding the existing high-grade resource. “We plan to conduct infill drilling to upgrade as much of the inferred resources as we can. Previous drilling traced the vein’s strike length for at least 875 meters,” added Docherty.
The PEA emphasized that the deposit remains open to the west, east and down-dip.
“It’s also important to remember that Deer Horn is largely unexplored over its 51 square kilometers,” added Docherty. “The gold, silver and tellurium represent only a portion of the targets we plan to explore further. For example, prospecting in 2012 identified new showings indicative of a buried copper porphyry system. We also have important concentrations of tungsten on the property. We will report more on these additional targets in the near future.”
Mineral Resource Estimate
The Mineral Resource Estimate has been prepared in accordance with NI 43-101 by Gary Giroux, P.Eng., qualified person under the meaning of NI 43-101, and summarized in the Table 1 below.
Table 1 - Deer Horn NI 43-101 Indicated and Inferred Mineral Resource Estimate
- This Mineral Resource Estimate was prepared by Gary Giroux, P.Eng. in accordance with NI 43-101, with an effective date of May 5, 2018.
- Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal or other relevant issues. The Mineral Resources have been classified according to the CIM Definition Standards for Mineral Resources and Mineral Reserves in effect as of the date of this news release.
- Metal assays were capped where appropriate.
- The Tellurium, Copper, Lead and Zinc resource was estimated with about ½ the data used to estimate Au and Ag.The reader should be aware that the confidence in the Te, Cu, Pb and Zn estimates are lower than the confidence on Au and Ag.
- A 1.0 g/t Au cut-off is chosen as a possible open pit mining cut-off for this deposit.This cut-off grade includes the following considerations: Gold Price of US$1,300/oz., Silver Price of US$17/oz., Tellurium price of US$100/kg, exchange rate of 0.8 US$:CDN$, process costs of $29 per tonne milled, process recovery of 90% and mining costs of $4/tonne mined.
Mineralized material from the Deer Horn deposit will be mined from an open pit. The mine will operate during the summer months only to keep costs low. The material will be processed using a conventional flowsheet including crushing, grinding and flotation to produce base metal concentrates with precious metals.
The pit delineated resources used as the basis for the PEA economics are included in Table 2. These resources are a subset of the Mineral Resource Estimate shown in Table 1.
Table 2 - Deer Horn NI 43-101 Pit Delineated Resources for PEA
- The pit delineated resource has an effective date of 15 May 2018.The Qualified Person for the estimate is Mr. Marc Schulte, P.Eng.
- Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. The estimate of Pit Delineated Mineral Resources may be materially affected by metal price assumptions, geologic interpretations and mineral resource estimates, metallurgical recovery assumptions, operating cost assumptions, surface rights, permitting, regulatory restrictions, environmental, legal or other relevant issues.
- The Mineral Resources have been classified according to the CIM Definition Standards for Mineral Resources and Mineral Reserves in effect as of the date of this news release.
- A $29/t NSR cut-off grade includes the following considerations: Gold Price of US$1,300/oz., Silver Price of US$17/oz., Tellurium price of US$70/kg, exchange rate of 0.8 US$:CDN$, process costs of $29 per tonne milled, process recovery of 90 %, mining costs of $4/tonne mined. Open pit layouts utilize overall pit slope angles of 44 degrees.
- The pit delineated resources are mined tonnes and grade, the reference point is the mill feed at the primary crusher.
- Mining recovery of 100% of mineralized tonnes and grade. Mining dilution of 50% at 0.133 g/t Au, 5.096 g/t Ag, 7.196 ppm Te, 0.005 % Cu, 0.001 % Pb, 0.011 % Zn, applied to the block modeled mineralized tonnes and grade.
- The preliminary economic assessment is preliminary in nature.The preliminary economic assessment includes Inferred material that is 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.
Capital and Operating Costs
The total estimated initial capital cost for the Deer Horn project is $28.3 million and sustaining capital is $2.6 million over the LOM. The estimated LOM operating costs are $94 per tonne mill feed. The following tables summarize the cost components:
