TORONTO, July 22, 2025 (GLOBE NEWSWIRE) -- Fury Gold Mines Limited (TSX and NYSE American: FURY) ("Fury" or the "Company") is pleased to announce preliminary metallurgical test results on its Ninaaskumuwin lithium discovery in the Eeyou Istchee James Bay Territory of Northern Quebec. The objective of the metallurgical test work was to characterize the mineralogy and metallurgical properties of the spodumene-bearing pegmatite intercepted in drilling. Results from the preliminary test work indicate that the Ninaaskumuwin lithium mineralization is amenable to conventional lithium extraction techniques with Heavy Liquid Separation resulting in recovery of 62.2% Lithium and a concentrate grade of 5.59% Li2O from a single composite sample. The metallurgical test work paired with the recently released drilling results of 32.35 (metres) m of 1.16% Li2O (see news release dated July 9, 2025) indicates that the Ninaaskumuwin lithium discovery warrants additional work.
Highlights from the test work:
- Samples analysed contain up to 42% spodumene;
- Spodumene is the sole lithium-bearing mineral identified;
- The pegmatite intercepted is free of impurities indicating that lithium concentrates suitable for lithium carbonate and lithium hydroxide battery grade products could possibly be produced;
- The Ninaaskumuwin pegmatite is a highly fractionated and fertile Lithium Cesium and Tantalum (LCT) pegmatite;
- Grades of the 85 samples analysed range from 0.02% to 3.71% Li2O and 0.36% to 6.30 % Fe2O3; and
- Recoveries of 62.2% Li and concentrate grade of 5.59% Li2O received from a single composite.
"We are encouraged by the metallurgical results from our newly acquired lithium asset in Quebec," commented Tim Clark, CEO of Fury. "This project, as well as the others acquired through the Quebec Precious Metals transaction, is a positive addition to our portfolio of mineral exploration assets and warrants future follow-up work to realize the full potential of the project."
Mineralogical Analysis
A mineralogical study of 58 samples selected from drill holes EE24-002 and EE24-003 was performed using an ECORE hyperspectral drill core scanner. The mineralogical compositions are summarized below:
- High percentage of spodumene (up to 42%);
- Abundance of albite (up to 70%), K-Feldspar (up to 42%) and quartz (up to 99%), and muscovite (up to 19%);
- Traces of beryl, calcite, columbite, manganese-columbite, elbaite, fluorapatite, amphibole, pyrite, spessartine, and iron oxides;
- Impure lithium-bearing minerals (lepidolite and petalite) were not identified, indicating that the mineralized pegmatite could possibly produce lithium concentrates suitable for lithium carbonate and lithium hydroxide battery grade products; and
- Cesium and tantalum levels and generally low K/Rb ratios indicate a high degree of magma fractionation and a high potential for lithium, cesium, and tantalum.
Metallurgical Tests
Tests were performed on 27 samples from the spodumene-bearing pegmatite intercepted in drill hole EE24-001 (127 - 151.85 m). Sample lengths ranged from 0.65 m to 1.05 m. Results are summarized below:
- Average density: 2.70 g/m3;
- Sieve analysis of 2,000 to 20 µm show that lithium bearing spodumene is evenly distributed across all size fractions;
- Four grinding tests were conducted over a time range of 5, 15, 30 and 40 minutes to obtain a P80 (particle size range) using a laboratory ball mill (sample: 500 g; balls: 10 kg; water: 250 ml). After filtration of the mill output, wet sieving was performed using a 212 µm sieve. The results show that under the grinding conditions a grinding time of 40 minutes is necessary to obtain a product ground at 80% passing 212 µm.
- A test was conducted by grinding a sample prepared to 100% passing 3.36 mm to generate a stable closed circuit at the ball mill level with a circulating load of 250%. From the tested material, the Ball mill Work index ("BWi") was calculated to be 11.35 Kwh/t. This is classified as a medium BWi.
Heavy Liquid Separation ("HLS")
HLS tests were performed on one metallurgical sample from a composite sample from EE24-001. The composite sample was crushed to 100% less than 3 mm. The -3 mm +0.02 mm size fraction was submitted for two stages of HLS testing at d=2.96 and d=2.8. A spodumene concentrate with 5.59% Li2O, recovering 62.2% of the lithium in 11.4% of the mass was achieved (Figure 1).

Elmer East
The Ninaaskumuwin lithium prospect is located on Fury's 100% owned Elmer East project which covers approximately 45,735 hectares (ha). Ninaaskumuwin is easily accessible from the paved Billy Diamond highway, approximately 60 kilometres (km) north of the 'km 381' rest stop where accommodation, catering, fuel, and power are available. The discovery sits approximately 50 km north of Rio Tinto plc's Galaxy Lithium project, acquired in March 2025 as part of the acquisition of Arcadium Lithium plc for USD 6.7 billion.
Drilling targeted a spodumene-bearing pegmatite outcrop, which returned surface samples of up to 3.92% Li2O. Highlights from the drill campaign include 32.35m of 1.16% Li2O from EE24-003 and 22.48m of 1.19% Li2O from EE24-002 (see news release dated July 9, 2025). The lithium mineralized spodumene-bearing pegmatite remains open at depth and along strike, warranting additional drilling.
"These preliminary results for lithium illustrate the very clean metallurgical character of the spodumene mineralization intercepted to date at Elmer East. We look forward to continuing to advance this promising discovery," commented Bryan Atkinson, SVP Exploration of Fury.
Technical and scientific information disclosed from neighbouring Galaxy project does not necessarily apply to the Elmer East project.
To carry out the metallurgical test work financial assistance was provided by the ministère des Ressources naturelles et des Forêts (MRNF). This financial support was granted as part of the fourth call for projects of the Mineral Exploration Support Program for Critical and Strategic Minerals ("MCS"). This program supports companies in the mineral exploration sector in carrying out their projects aimed at developing MCS deposits in Quebec.
Mineralogical analysis and metallurgical tests were conducted by IGS Impact Global Solutions Inc. ("IGS"), in their laboratory in Delson, Quebec.
Metallurgical test work was completed by analysing ½ HQ drill core samples prepared using IGS's procedure P/SMu/02 ISO-17025-version 2017 as follows:
· Drying
· Weighing
· Crushing P80 = 2 mm
· Splitting (1/2, 1/4, 1/8, 1/16 a, 1/16 b)
· Preparation of a representative composite and division into subsamples of 500g each for testing
