U.S. GoldMining Inc. Selects Ausenco to Deliver Initial Economic Assessment At Whistler Gold-Copper Project, Alaska
, June 9, 2025 /CNW/ - U.S. GoldMining Inc. (NASDAQ: USGO) (" U.S. GoldMining" or the " Company") is pleased to announce it has selected Ausenco Engineering Canada ULC (" Ausenco") as the principal consulting firm to lead its proposed initial assessment study (" PEA") for the Whistler Gold-Copper Project (" Whistler" or the " Project"), located 105 miles northwest of Anchorage, Alaska. The study, as previously announced April 15, 2025, is intended to constitute an initial assessment under U.S. Regulation S-K 1300 (" S-K 1300") and a preliminary economic assessment under Canadian National Instrument 43-101 (" NI 43-101"). Highlights: The PEA is intended to explore and outline a development opportunity at the Whistler Project for a stand-alone open pit mine and concentrator facility located approximately 100 miles northwest of Anchorage in south-central Alaska, a region which has significant existing and ongoing infrastructure development. The PEA will consider the Whistler mineral resource estimate which currently stands at 6.48 million ounces (Moz) gold equivalent (AuEq) compiled from the indicated resource category and 4.16 Moz AuEq in the inferred resource category (see Table 1 for details). The Project is anticipated to benefit from the deposit's near-surface, higher-grade core material in the early years of production. The PEA will utilize an updated mineral resource estimate to be completed by Moose Mountain Technical Services, which will include 2024 drilling that was not available for the previous mineral resource estimate. In addition, metallurgical test work is currently being conducted by Base Metallurgical Laboratories Ltd., as previously announced on April 24, 2025. The Company completed a comprehensive bidding process, receiving initial expressions of interest from 13 consulting firms, followed by a rigorous Request for Proposal (" RFP") review of six shortlisted candidate firms. Ausenco was selected from this process on the strength of its experience across all disciplines and its track record in recent delivery of comparable studies. Tim Smith, Chief Executive Officer of U.S. GoldMining, commented:"We're delighted to be able to announce that we have partnered with Ausenco on this important work program.

Mineral resources are not mineral reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the mineral resources will be converted into mineral reserves. 2. Inferred mineral resources are subject to uncertainty as to their existence and as to their economic and legal feasibility. The level of geological uncertainty associated with an inferred mineral resource is too high to apply relevant technical and economic factors likely to influence the prospects of economic extraction in a manner useful for evaluation of economic viability. 3. The mineral resource estimate for the Whistler, Island Mountain, and the upper portions of the Raintree West deposits have been confined by an open pit with "reasonable prospects of economic extraction" using the following assumptions: Metal prices of US$1,850/oz gold (Au), US$4.00/lb copper (Cu) and US$23/oz silver (Ag); Payable metal of 95% payable for Au and Ag, and 96.5% payable for Cu; Refining costs for g of US$8.00/oz, for Ag of US$0.60/oz and for Cu of US$0.05/lb; Offsite costs for Au of US$77.50/wmt, for Ag of US$3.50/wmt and for Cu of US$55.00/wmt; Royalty of 3% net smelter return royalty (NSR); Pit slopes are 50 degrees; Mining cost of US$2.25/t for waste and mineralized material; and Processing, general and administrative costs of US$7.90/t. 4. The lower portion of the Raintree West deposit has been constrained by a mineable shape with "reasonable prospects of eventual economic extraction" using a US$25.00/t cut-off. 5. Metallurgical recoveries are: 70% for Au, 83% for Cu, and 65% Ag for Ag grades below 10g/t. The Ag recovery is 0% for values above 10g/t for all deposits. 6. The NSR equations are: below 10g/t Ag: NSR (US$/t)=(100%-3%)*((Au*70%*US$54.646/t) + (Cu*83%*US$3.702*2204.62 + Ag*65%*US$0.664)), and above 10g/t Ag: NSR (US$/t)=(100%-3%)*((Au*70%*US$56.646g/t) + (Cu*83%*US$3.702*2204.62)). 7. The Au Equivalent equations are: below 10g/t Ag: AuEq=Au + Cu*1.771 +0.0113Ag, and above 10g/t Ag: AuEq=Au + Cu*1.771. 8. The specific gravity for each deposit and domain ranges from 2.76 to 2.91 for Island Mountain, 2.60 to 2.72 for Whistler with an average value of 2.80 for Raintree West. 9. Numbers may not add due to rounding.

Piedmont Lithium Announces Q1'25 North American Lithium Production Results
BELMONT, N.C.--(BUSINESS WIRE)--Piedmont Lithium Inc. ('Piedmont,' the 'Company') (Nasdaq: PLL; ASX: PLL), a leading North American supplier of lithium products critical to the U.S. electric vehicle supply chain, today announced that it shipped approximately 27,000 dry metric tons ('dmt') of spodumene concentrate in Q1'25. NAL, North America's largest producing spodumene mine, is jointly owned by Piedmont (25%) and Sayona Mining Limited (75%) (ASX: SYA). Q1'25 OPERATIONAL RESULTS SUMMARY NAL 1 Units Q1'25 Q4'24 QoQ Variance Q1'24 YoY Variance Ore Mined kt wmt 322.4 370.4 (13%) 351.1 (8%) Concentrate Produced kt dmt 43.3 50.9 (15%) 40.4 7% Plant (Mill) Utilization % 80% 90% (10%) 73% 7% Lithium Recovery % 69% 68% 1% 67% 2% Concentrate Sold kt dmt 27.0 66.0 (59%) 58.1 (53%) Expand In Q1'25, NAL produced 43,261 dmt and sold approximately 27,000 dmt. All tons sold by NAL were sold to Piedmont under the Company's offtake agreement and then shipped to Piedmont's customers. Quarterly production at NAL declined by 15% in Q1'25 compared to the prior quarter but production remains on track to achieve Sayona Mining's fiscal year 2025 production guidance of 190,000 – 210,000 dmt 2. Lithium recovery remained high at 69% and set a new record of 72% in March, while mill utilization declined due the combination of unplanned, weather-related downtime and a 5-day scheduled shutdown. The crushed ore dome mitigated the impact of the weather-related downtime and additional mobile crushing capacity has been brought on site to lessen the impact of weather on a go-forward basis. 'While NAL operated under challenging conditions to begin 2025 and produced fewer tons than anticipated, adjustments implemented since the restart of production have improved operational resilience. These steps give us confidence in our ability to improve performance and reduce weather-related disruptions in the future,' said Keith Phillips, President and CEO of Piedmont Lithium.

U.S. GoldMining Inc. Commences Metallurgical Testwork At Whistler Gold-Copper Project, Alaska
ANCHORAGE, Alaska, April 24, 2025 /CNW/ - U.S. GoldMining Inc. (NASDAQ: USGO) (" U.S. GoldMining" or the " Company") is pleased to announce it has commenced metallurgical testwork, which will help to inform the proposed initial economic assessment for the Whistler Gold-Copper Project (" Whistler" or the " Project"), located 105 miles northwest of Anchorage, Alaska. As previously announced on April 15, 2025, the proposed study (the " PEA") will be intended to constitute an initial assessment under U.S. Regulation S-K 1300 (" S-K 1300") and a preliminary economic assessment under Canadian National Instrument 43-101 (" NI 43-101"). Highlights: The principal aim of the metallurgical testwork is to develop a preliminary process flowsheet optimized for metal recovery for the Whistler gold-copper mineralization, that will be used in the proposed PEA. The Company has engaged Base Metallurgical Laboratories Ltd., (" BaseMet") located in Kamloops, B.C., Canada, to undertake the testwork. BaseMet's specialties include mineral processing, gold extraction technologies, comminution, geometallurgy and applied mineralogy, with experience gained throughout North America and internationally across dozens of gold-copper projects for some of the largest mining companies in the world. Metallurgical testwork will comprise: Preparation of variability composites and a master composite prepared from drill core samples collected at the Whistler Deposit during the 2023 – 2024 drill seasons. Feed characterization by head assaying and QEMSCAN (scanning electron microscopy) mineralogy. Detailed mineralogy on the master composite, including a gold deportment study. Comminution testing to determine the crushing and grinding process. Sulphide flotation testing to determine the chalcopyrite concentrate process path. Gravity gold and cyanide leaching on concentrate tailings to further optimize gold recoveries. Tim Smith, Chief Executive Officer of U.S. GoldMining, commented:"The Company is delighted to kick off one of the cornerstone studies intended to inform a robust PEA for the Project. Previous metallurgical testwork concluded that the Whistler gold-copper porphyry mineralization is amenable to a conventional flotation route that produces a saleable high quality copper concentrate with gold and silver credits. With previous testwork indicating recoveries of 70% and 83% for gold and copper respectively, we believe that there is room for recovery optimization. Our mission with this current round of testwork is to follow-up on the previous conventional flotation testwork and to optimize the process path. Additional variability data points will enable us to understand metal recoveries in different parts of the deposit, and to quantify the extent to which cyanide leaching can potentially return improved gold recoveries."
