P2 Gold Announces Positive Gabbs Updated Preliminary Economic Assessment with Life of Mine Production of 1.86 Million Gold Equivalent Ounces

P2 Gold Announces Positive Gabbs Updated Preliminary Economic Assessment with Life of Mine Production of 1.86 Million Gold Equivalent Ounces

Canada NewsWire

VANCOUVER, BC , Sept. 11, 2023 /CNW/ - P2 Gold Inc. ("P2" or the "Company") (TSXV: PGLD) (OTCQB: PGLDF) reports results from a positive Updated Preliminary Economic Assessment ("Updated PEA") on its wholly-owned gold-copper Gabbs Project located on the Walker-Lane Trend in Nevada . The Updated PEA was prepared by Kappes, Cassiday & Associates ("KCA") of Reno, Nevada with Mineral Resource and mining contributions from P&E Mining Consultants Inc. ("P&E") in accordance with National Instrument 43-101, Standards of Disclosure for Mineral Projects ("NI 43-101"). An NI 43-101 Technical Report will be prepared and posted on www.p2gold.com and the Company's profile on www.SEDAR.com within 45 days of the date of this news release.

PEA Highlights
  • After-tax net present value (5% discount rate) of US$292.2 million and internal rate of return of 17.0% at US$1918 /oz gold, US$23.01 /oz silver and US$3.73 /lb copper ("Spot Metal Prices") (See spot to base case price comparison in Table 1)



  • Total projected life-of-mine ("LOM") revenue of US$3.43 billion at Spot Metal Prices over 13.4-year mine life



  • LOM gold equivalent production of 1.86 million ounces (79.1 million tonnes @ 0.54 g/t gold, 1.28 g/t silver and 0.27% copper) at Spot Metal Prices, with LOM production of 1.206 million ounces of gold, 1.742 million ounces of silver and 327 million pounds of copper



  • Average annual gold equivalent production of 139,000 ounces at Spot Metal Prices



  • Estimated pre-production capital cost, including contingencies, of US$277.7 million with payback of 3.0 years at Spot Metal Prices

"We have updated the Gabbs June 2023 PEA to include the development of the sulphide mineralization in addition to oxide mineralization and an increase in the mining rate to six million tonnes per year to provide for the development of a mid-sized mine," commented Joe Ovsenek , President and CEO of P2. "Life-of-Mine production at Gabbs is now expected to be close to two million ounces of gold equivalent with average annual production expected to be close to 150,000 ounces of gold equivalent. The updated PEA contemplates heap leach processing as the first phase of operations for the initial five years to reduce upfront capital requirements and project risks. Heap leach operations will pay for preproduction capital and a significant portion of mill capital prior to the commencement of mill processing in year six. The Gabbs Feasibility Study, expected to be initiated soon, will focus on optimizing the mine plan and capex, evaluating contract mining and completing additional metallurgy, which we believe will significantly increase the rate of return. What's more, Gabbs has considerable Mineral Resource expansion potential for both oxides and sulphides, which is why we expect Gabbs to be a long-life gold and copper mine."

The Updated PEA is preliminary in nature, 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 Updated PEA will be realized. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. The Company has not defined any Mineral Reserves on the Gabbs Project.

Economic Sensitivities

Base Case metals prices were established by the Company reflecting the Company's expectations for market conditions at the time of construction financing for the Gabbs Project and to allow for a direct comparison with the Gabbs June 2023 Preliminary Economic Assessment (see news release dated June 29, 2023 ).

Mining and Processing

Mining

The mineralized material will be mined by standard open-pit mining methods using an owner mining fleet of 136-tonne haul trucks and 15.3 m 3 hydraulic shovels, fine crushed using a system incorporating a jaw crusher, cone crushers and high-pressure grinding rollers (HPGR).

Processing

Heap Leach

The Gabbs mineralized material is estimated to contain an average of 0.27% copper based on the mine plan used for this Updated PEA. A portion of this copper is cyanide soluble and is expected to be extracted in the heap leach circuit. The cyanide soluble copper has an effect on the cyanide consumption. A SART (sulfidization, acidification, recycling and thickening) plant that releases cyanide associated with the copper cyanide complex, allowing it to be recycled back to the leach process as free cyanide is included. The resulting copper precipitate will be sold, bringing additional revenue to the project.

After the crushing circuit, the mineralized material will be agglomerated with cement and conveyor stacked on the heap leach pad in 8-meter lifts then single-stage leached with a dilute cyanide solution. The gold and copper bearing solution will be collected in the pregnant solution pond and pumped to the SART plant. Pregnant solution will be acidified with sulfuric acid, then copper will be precipitated as sulfides by the addition of sodium hydrosulfide. The precipitate will be thickened and filtered to produce a copper filter cake for shipment to a smelter. The barren solution from the SART plant will be processed in a carbon adsorption-desorption-recovery (ADR) plant to recover gold. The gold will be periodically stripped from the carbon using a desorption process. The gold will be plated on stainless steel cathodes, removed by washing, filtered, dried and then smelted to produce a doré bar.

Mill

The ROM feed material to the mill will use the same crushing circuit as the heap leach facilities. The mill feed will be crushed to P80 6.3 mm, (1/4") in a three-stage crushing circuit, with the third-stage an HPGR. The ore will be conveyed to a single-stage ball mill circuit. Sulfide and oxide mineralized material will be campaigned through the mill as the oxide material will not be treated in the flotation circuit. The milled sulphide product will be treated in a flotation plant to produce a copper concentrate suitable for sale. The flotation tailings and ground oxide material will be thickened, then direct cyanide leached to dissolve gold, silver and copper. The leached solids will be washed in a CCD circuit to remove the dissolved metals and cyanide. The dissolved copper and silver will be recovered from the CCD overflow solution in a SART plant as a copper/silver sulphide precipitate. Regenerated sodium cyanide from the SART plant will be recycled to the leach circuit. Gold in the SART plant barren solution will be recovered in an ADR plant and refined to produce doré bars. The CCD tails are treated in a cyanide destruction circuit, filtered, and conveyed to a "dry stack" storage facility.

Opportunities
  • Low-Grade Stockpile – evaluate alternatives for processing low-grade stockpile
  • Leased Mining Fleet– evaluate leasing versus purchasing the mining fleet
  • Contract Mining - evaluate contract mining versus owner fleet
  • Mine Plan – optimize mine sequencing to increase return on capital and carryout geotechnical drilling to optimize pit slope angles
  • Stripping - evaluate extent of alluvium in waste to reduce stripping cost
  • Mineral Resource – expand oxide and sulphide gold and gold and copper mineralization (zones remain open)
  • Metallurgy – complete additional test work to increase recoveries for oxide and sulphide mineralization and evaluate the use of HPGR for potential heap leaching of sulphide mineralization to increase recovery of free gold
  • Capex – evaluate equipment alternatives to reduce capital costs
Next Steps

Additional metallurgical test work will be undertaken next to refine metallurgical recoveries for both the oxide and sulphide mineralization along with an evaluation of the depth of the alluvium and geotechnical drilling. Thereafter, Feasibility level studies will commence and will include an evaluation of contract mining versus an owner fleet (leased or owned), mine plan optimization and equipment alternatives. Timing of the metallurgical test work, drilling and Feasibility level studies will be dependent on the availability of funds.

Gabbs Project 2023 Mineral Resource Estimate

The June 2023 Updated Mineral Resource Estimate ("2023 MRE") was prepared by P&E based on four diamond drill holes and 27 reverse circulation drill holes completed by the Company in 2021 and 2022 and 494 drill holes completed by prior Gabbs Project operators between 1970 and 2011. The 2023 MRE is restated in this news release to include silver.

The main difference between the 2023 MRE and the February 2022 Mineral Resource Estimate ( see news release dated February 10, 2022 ) is the decrease in the oxide cutoff grade to 0.28 g/t gold equivalent from 0.35 g/t gold equivalent and an increase in the sulphide cutoff grade to 0.44 g/t gold equivalent from 0.36 g/t gold equivalent. As a result, oxide Mineral Resources have increased and sulphide Mineral Resources have decreased.

(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, sociopolitical, 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), Standards on Mineral Resources and Reserves, Definitions (2014) and Best Practices (2019) prepared by the CIM Standing Committee on Reserve Definitions and adopted by CIM Council.

(4)

The Mineral Resource Estimate was prepared for a potential open pit scenario using a constraining pit shell (with 50 degree slopes) at respective 0.28 g/t and 0.44 g/t oxide and sulphide gold equivalent cut-off grades. The gold equivalent cut-off grades were derived from US$1,838/oz gold, US$3.96/lb copper, US$2.15/tonne mining cost, and US$11.76 and $23.66/tonne respective oxide and sulphide processing costs; US$1.25/tonne G&A cost, 78.3% and 95.2% respective Au oxide and sulphide process recoveries; and 48% and 78% respective Cu oxide and sulphide process recoveries.

(5)

Silver not included in gold equivalent calculation.

Oxide Mineral Resources at Gabbs consist of Indicated Mineral Resources of 724,400 ounces of gold equivalent (30.6 million tonnes grading 0.49 g/t gold, 1.49 g/t silver and 0.27% copper) and Inferred Mineral Resources of 779,000 ounces of gold equivalent (33.0 million tonnes grading 0.53 g/t gold, 1.03 g/t silver and 0.23% copper). See Table 7 below for a breakdown of the oxide and sulphide Mineral Resources.
