Vancouver, B.C. - Spanish Mountain Gold Ltd. (the “Company”) (TSX-V:SPA) is pleased to announce the results of the Preliminary Economic Assessment (the “PEA”) for the high priority near-surface Phase 1 Project of the 100% owned Spanish Mountain gold project (the “Project”) located in central British Columbia, Canada. The PEA, the commencement of which was announced in a news release dated September 10, 2019, has been prepared in accordance with NI 43-101 Standards of Disclosure for Mineral Projects.
As disclosed in the September 10, 2019 news release, the PEA is based on a 10,000 tonnes per day (tpd) mill rate to process the near-surface Measured and Indicated Resources within an open pit focussed on the central higher-grade resources within the deposit.
As a stand-alone operation spanning more than a decade, the PEA envisages a low-cost, owner-operated open pit mine processing 39 million tonnes of material at an average diluted grade of 1.00 gram/tonne gold (g/t Au). The process involves a three-stage crushing circuit followed by a ball mill to produce a relatively coarse grind of 180 micron which is then concentrated by flotation to produce a concentrate for fine grinding and cyanidation at an overall gold recovery of 91%.
Highlights of the PEA are as follows (all amounts are in Canadian dollars unless otherwise indicated; base case is stated using a gold price of US$ 1,275 per ounce and an exchange rate of $C1.00 equal US$0.75):
- This first phase of operation has a mine life of 11 years with peak production of 130,000 ounces per annum (Year 4) and an average LOM annual production of 104,000 ounces of gold for a total of 1,145,000 ounces
- Initial capital is estimated to be C$364M (or US$273M), which includes a contingency of C$42M. Sustaining capital over the life of the mine is estimated to be C$58M
- Average metallurgical recovery of gold is 91%
- Selected operational and cost metrics are shown in the table below:
|Unit||Year 1 – 5|
|Life of Mine|
|Annual Gold Production||Koz||116||104|
|Cash Cost / oz||US$||481||511|
|All-in-sustainable Cost / oz||US$||519||549|
|Total Cost / oz||US$||776||807|
- Economic results at various gold prices are shown in the table below with the base case price assumption in bold:

Larry Yau, CEO, commented: “I believe the PEA has successfully met our objective of defining a Project with a greatly enhanced profile. Our project now has initial capital requirements that are $143 million less and a planned mill feed grade that is 150% greater than in previous studies while maintaining a robust production profile and achieving improved economic metrics. Furthermore, all portions of the deposit outside the current planned mill feed pit that were identified in previous studies remain available for future evaluation.
The current PEA clearly provides a reasonable basis for the Company to advance the Project in the present gold price environment.”

The Phase 1 mine plan includes 39 Mt of mill feed and 139 Mt of waste over the 11-year project life. The mill feed is comprised entirely of Measured and Indicated Resources. Approximately 0.7 Mt of Inferred material within the pit has been treated as waste for this study.
|PEA Mine Plan Summary||Unit||Amount|
|Measured and Indicated Mill Feed||Mt||39.10|
|Measured and Indicated Gold||koz||1,258|
|Measured and Indicated Silver||koz||927|
|Mine Plan Waste (includes Inferred)||Mt||138.50|
The above mine plan is based on a sub-set of a Mineral Resource Estimate for the Spanish Mountain gold deposit prepared by independent Qualified Person Sue Bird, P. Geo. of MMTS with an effective date of October 10, 2019.
The Pit-Delineated Mineral Resource Estimate consists of 4.1 million ounces gold and 6.2 million ounces silver Measured and Indicated (29.6 Mt Measured grading 0.60 g/t Au, 0.83 g/t Ag and 243.6 Mt Indicated grading 0.46 g/t Au, 0.69 g/t Ag for combined Measured and Indicated Resources of 273.2 Mt grading 0.47 g/t Au, 0.71 g/t Ag). Inferred Mineral Resources consist of 0.6 million ounces gold and 1.1 million ounces silver (52.5 Mt Inferred grading 0.37 g/t Au, 0.67 g/t Ag).
Notes for the Mineral Resources and PEA Mine Plan:
- The Mineral Resource Estimates were prepared by Sue Bird, P.Eng. (who is also the independent Qualified Person for these Mineral Resource Estimates), in accordance to the 2014 Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) Definition Standards for Mineral Resources and Mineral Reserves, with an effective date of October 10, 2019.
- The Mineral Resource Estimates are reported at a cutoff grade of 0.15 g/t.
- Cut-off grade assumes US$1,275/oz. Au at a currency exchange rate of 0.75 C$ per US$; 99.8% payable gold; $4.00/oz. offsite costs (refining and transport), a 1.5% royalty; and uses a 91% metallurgical recovery. The cut off-grade covers processing costs of $5.00/t and general and administrative (G&A) costs of $2.25/t.
- The Mineral Resources are constrained by an open pit shell generated by applying the Lerchs-Grossman algorithm to the Spanish Mountain deposit. The pit shell was generated using the same inputs as the cutoff grade determination, as well as a $2.20/t mining cost. Overall pit slope angles range from 20 degrees to 43 degrees and are estimated based on geotechnical analysis of various zones in the deposit.
- The PEA Mine Plan and Mill Feed estimates are a subset of the October 10, 2019 Mineral Resource estimates and are based on open pit mine engineering and technical information developed at a Scoping level for the Spanish Mountain Gold deposit.
- PEA Phase 1 Mine Plan and Mill Feed estimates are mined tonnes and grade, the reference point is the primary crusher.
- Mining recovery of 97% and external mining dilution of 10.9% at 0.34 g/t Au grade is applied in addition to the modelled in-block dilution.
- Factors that may affect the estimates include: metal price assumptions, changes in interpretations of mineralization geometry and continuity of mineralization zones, changes to kriging assumptions, metallurgical recovery assumptions, operating cost assumptions, confidence in the modifying factors, including assumptions that surface rights to allow mining infrastructure to be constructed will be forthcoming, delays or other issues in reaching agreements with local or regulatory authorities and stakeholders, and changes in land tenure requirements or in permitting requirement. Any other known legal, political, environmental, or other risks that could materially affect the potential development of the Mineral Reserves are detailed below in the section entitled “Forward-Looking Statements”.
- Estimates have been rounded and may result in summation differences.
Mineral resources, which are not mineral reserves, do not have demonstrated economic viability. Inferred mineral resources have insufficient confidence to allow the meaningful application of technical and economic parameters or to enable an evaluation of economic viability suitable for public disclosure.
Processing of the mill feed is by means of a conventional process flowsheet including primary grinding, flotation, gravity concentration of cleaner tails, regrinding of the concentrate, and cyanidation via a CIL circuit to produce doré. The process achieves an average overall LOM gold recovery of 91%. A silver recovery of 27% is assumed for the life of the project. Tailings from the plant are stored in a tailings management facility that has been designed to minimize water above the dam. The balance of the site water is managed through a separate water management pond that includes a water treatment plant for any water to be discharged.

The following table summarizes the estimated capital costs:
|Direct Costs||Initial Capital Cost |
|Open Pit Mining||70.2|
|Processing Plant (including Ore Handling)||77.4|
|Tailing Management Facility & Water Management||46.7|
|Total Initial Capital Cost||$363.8|
LOM sustaining capital requirements are estimated at C$ 57.8 million.

|Mining ($/t mined)||$2.48|
|Mining ($/t milled)||$10.73|
|Processing ($/t milled)||$6.14|
|Tailings ($/t milled)||$0.16|
|G&A ($/t milled)||$2.06|
|Total ($/t milled)||$19.10|
Other Assumptions used for the financial analysis are as follows:
- 99.8% payable gold and 90% payable silver.
- US$1.00/oz. gold refining charges and US$0.60/oz. silver refining charges.
- US$1.00/oz. transport charges on produced gold and silver.
- 0.15% insurance on value of produced gold and silver.
- 1.5% NSR royalty.
Opportunities to Enhance Value
Although Spanish Mountain considers the PEA results for the base case to be excellent, future studies are anticipated to evaluate alternate development scenarios that would be used to enhance the overall value of the project beyond the Phase 1 base case that is the basis for the PEA. Minor changes to the process flowsheet may improve gold recovery. Furthermore, a staged development wherein the Phase 1 project is followed by expansion is one alternate scenario being considered. Moreover, the current pit-constrained resource is focused on only one portion of the overall deposit.

Cautionary Note Regarding Preliminary Economic Assessment
Preliminary Economic Assessment summarized herein is preliminary in nature and is based on measured and indicated mineral resources. A measured or indicated mineral resource is that part of a mineral resource for which quantity, grade or quality, densities, shape and physical characteristics are estimated with sufficient confidence to allow the application of Modifying Factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit. An inferred mineral resource is that part of a mineral resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. Geological evidence is sufficient to imply but not verify geological and grade or quality continuity. Mineral resources, that are not mineral reserves, do not have demonstrated economic viability. There is no certainty that the PEA will be realized.
Cautionary Note Regarding Mineral Resources and Mineral Reserves
Readers should refer to the Company's current technical reports and other continuous disclosure documents filed by the Company, available at www.sedar.com for further information the mineral resource estimates of the Company's projects, which are subject to the qualifications and notes set forth therein, as well as for additional information relating to the Company more generally.
Neither the Company, nor readers, should assume that all or any part of an inferred mineral resource will be upgraded to indicated or measured mineral resources. Most projects at the inferred mineral resource stage do not ever form the basis of feasibility or other economic studies, or achieve successful commercial production. Each stage of a project is contingent on the positive results of the previous stage and that there is a significant risk that the results may not support or justify moving to the next stage.
