P2 Gold Announces Positive Gabbs Preliminary Economic Assessment
VANCOUVER, BC, June 29, 2023 /CNW/ - P2 Gold Inc. ("P2" or the "Company") (TSXV: PGLD) (OTCQB: PGLDF) reports results from a positive Preliminary Economic Assessment ("PEA") on its wholly-owned gold-copper Gabbs Project located on the Walker-Lane Trend in Nevada. The PEA was prepared by Kappes, Cassiday & Associates ("KCA") of Reno, Nevada with Mineral Resource and mining contributions from P&E Mining Consultants Inc. 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
Open pit, heap leach operation focused predominantly on oxide gold and copper Mineral Resources (Phase One), mining 43.4 million leachable tonnes and 102.3 million waste tonnes
After-tax net present value (5% discount rate) of US$163.1 million and internal rate of return of 16.7% at US$1,950 gold and $4.50 copper
Mine life of 11.1 years, with an average processing rate of 11,000 tonnes per day
LOM gold equivalent production of 837,000 ounces (43.4 million tonnes @ 0.54 g/t gold and 0.25% copper) and LOM gold production of 562,100 ounces
Estimated pre-production capital cost, including contingencies, of US$230.2 million
"The PEA provides a solid plan for advancing Phase One development at Gabbs, where we are taking a phased approach to production," commented Joe Ovsenek, President and CEO of P2. "With an initial focus primarily on the oxide resources, we can shorten and simplify the path to production with an open pit, heap leach operation. Our next goal is to optimize the mine plan and capex, evaluate contract mining and complete additional metallurgy, which we believe will significantly increase the rate of return at lower metal prices. In addition, Gabbs has considerable oxide Mineral Resource expansion potential to extend Phase One operations beyond that contemplated in the PEA. Phase Two will focus on the development of the sulphide mineralization which sits below the oxide mineralization. Overall, we expect Gabbs to be a long-life gold and copper mine as the oxide mineralization is expanded and the sulphide mineralization is brought online."
The 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 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.

Mining and Processing
Mining
The mineralized material will be mined by standard open-pit mining methods using an owner mining fleet of 90-tonne haul trucks and 11 m3 hydraulic shovels, fine crushed using a system incorporating a jaw crusher, cone crushers and high-pressure grinding rolls (HPGR), agglomerated with cement and conveyor stacked on the heap leach pad in 8-metre lifts.
Processing
The Gabbs mineralized material is estimated to contain an average of 0.25% copper based on the mine plan used for this 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.
Mineralized material will be 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.
Opportunities
Contract Mining – evaluate contract mining versus owner fleet
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
Mineral Resource – expand oxide gold and gold and copper mineralization
Capex – evaluate equipment alternatives to reduce capital costs
Mine plan – optimize mine sequencing to increase return on capital
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 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 cut-off grade to 0.28 g/t gold equivalent from 0.35 g/t gold equivalent and an increase in the sulphide cut-off 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.

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.
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 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 and 0.23% copper). See Table 5 below for a breakdown of the oxide and sulphide Mineral Resources.

Next Steps
Additional metallurgical test work will be undertaken next to refine metallurgical recoveries for both the oxide and sulphide mineralization. Thereafter, feasibility level studies will commence and will include an evaluation of contract mining versus an owner fleet, equipment alternatives and mine plan optimization. Timing of the metallurgical test work and feasibility level studies will be dependent on the availability of funds.
