P2 Gold Announces Significant Increase in Mineral Resource for Gabbs
VANCOUVER, Feb. 10, 2022 - P2 Gold Inc. ("P2" or the "Company") (TSX-V:PGLD) reports the completion of the February 2022 Updated Mineral Resource Estimate ("2022 MRE") for its wholly-owned Gabbs Project located on the Walker-Lane Trend in Nevada. The 2022 MRE is the first update to the Mineral Resource estimate for Gabbs since the Company acquired the Project in 2021. Gold-equivalent Mineral Resources at Gabbs have been upgraded and increased significantly as a result of the 2021 drill program, metallurgical test work and increased understanding of the geologic controls on the gold-copper mineralization.
Highlights
Gold equivalent Pit Constrained Mineral Resources at Gabbs comprise:
- Indicated Mineral Resource of 1.12 million ounces of gold equivalent or 0.65 million ounces of gold and 266.7 million pounds of copper (43.4 million tonnes grading 0.47 g/t gold and 0.28% copper)
- Including, Oxide Indicated Mineral Resource of 576,000 ounces of gold equivalent or 0.39 million ounces of gold and 127.9 million pounds of copper (20.1 million tonnes grading 0.61 g/t gold and 0.29% copper)
- Inferred Mineral Resource of 1.64 million ounces of gold equivalent or 0.88 million ounces of gold and 376.1 million pounds of copper (69.9 million tonnes grading 0.39 g/t gold and 0.24% copper)
Prior to the 2022 MRE, the Gabbs Project had an Inferred Mineral Resource ("2021 MRE") of 1.84 million ounces of gold equivalent or 1.26 million ounces of gold and 422.3 million pounds of copper (73.1 million tonnes grading 0.54 g/t gold and 0.26% copper) (see P2 news release of February 23, 2021).
Gabbs Project February 2022 Mineral Resource Estimate
The 2022 MRE was prepared by P&E Mining Consultants Inc. ("P&E"), based on four diamond drill holes and 27 reverse circulation drill holes completed by the Company in 2021 and 494 drill holes completed by prior Gabbs Project operators between 1970 and 2011. A National Instrument 43-101 Technical Report will be prepared by P&E 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.
Table 1: February 2022 Gabbs Project Pit Constrained Mineral Resource Estimate(1)(2)(3)(4)
| Mineral Resource Classification | Tonnes (M) | Gold Grade (g/t) | Copper Grade (%) | Gold (M oz) | Copper (M lbs) | Gold Eq. Grade (g/t) | Gold Eq. (M oz) |
| Indicated | 43.4 | 0.47 | 0.28 | 0.65 | 266.7 | 0.81 | 1.12 |
| Inferred | 69.9 | 0.39 | 0.24 | 0.88 | 376.1 | 0.73 | 1.64 |
| (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 0.35 g/t and 0.36 g/t oxide and sulphide gold equivalent cut-off grades. The gold equivalent cut-off grades were derived from US$1,675/oz gold, US$3.80/lb copper, US$2.14/tonne mining cost, and US$13.81 and $17.34/tonne respective oxide and sulphide processing costs; US$0.68/tonne G&A cost, 76% and 94% respective Au oxide and sulphide process recoveries; and 48% and 87% respective Cu oxide and sulphide process recoveries. |
Oxide Mineral Resources at Gabbs now consist of Indicated Mineral Resources of 576,000 ounces of gold equivalent (20.1 million tonnes grading 0.61 g/t gold and 0.29% copper) and Inferred Mineral Resources of 260,000 ounces of gold equivalent (9.9 million tonnes grading 0.61 g/t gold and 0.19% copper). See Table 2 below for a breakdown of the oxide and sulphide Mineral Resources.

The majority of the increase in the 2022 MRE (from the 2021 MRE) occurred at the Sullivan Zone where the Company drilled 27 drill holes (four diamond drill holes and 23 reverse circulation drill holes) in 2021. The Inferred Mineral Resource at the Lucky Strike Zone also increased in the 2022 MRE, whereas the Inferred Mineral Resource changed nominally at Car Body and Gold Ledge. See Table 3 below for a breakdown of the Gabbs Mineral Resource by zone.

Metallurgical Test Results
The Company retained Kappes, Cassiday & Associates (KCA) in Reno, Nevada to carry out a Phase Two metallurgical program to determine the preferred extraction process for the Gabbs mineralization. Based on work completed to date, KCA is proposing that the oxide material be heap leached and gold recovered as a salable dor? and cyanide soluble copper produced as a salable copper sulphide concentrate. For the sulphide material, KCA is proposing flotation to recover a salable copper concentrate with the flotation tails cyanide leached to recover additional gold as a salable dor? and cyanide soluble copper as a copper sulphide concentrate.
Gold and copper recoveries used for the 2022 MRE were based on historical metallurgical testwork and recently completed metallurgical tests at KCA. For the oxide material, gold and copper recoveries were assumed to be 76% and 48%, respectively. For the sulphide material: (a) gold recovery to copper flotation concentrate was assumed to be 72% and gold recovery from rougher flotation tails was assumed to be 78.0% for a weighted gold recovery of 94%; and (b) copper recovery was assumed to be 79% to flotation concentrate and 7.6% from cyanide soluble copper precipitation for a weighted recovery 87%. Metallurgical testing by KCA is ongoing.
