7 terms

g/t au technical

"Final assays include 9.4 g/t Au over 2.2 metres..."

g/t Au stands for grams per tonne of gold and measures how much gold is contained in one tonne of rock or ore. Investors use it like a yield rate: higher g/t Au means more gold recovered from the same amount of material, which usually improves a mine’s revenue potential and lowers production cost per unit of metal. Think of it as the sweetness level of fruit—more sugar per piece makes each piece more valuable.

fire assay technical

"Gold analyses were performed by 30 g Fire Assay with Atomic Absorption Spectrometry finish..."

Fire assay is a laboratory process used to accurately measure the amount of precious metals, like gold or silver, in a sample of ore or material. It involves heating the sample intensely to separate the metals from other substances, much like melting and purifying metal to determine its purity. This method is important to investors because it provides precise data on the metal content, helping to assess the value of mining operations or mineral deposits.

atomic absorption spectrometry technical

"30 g Fire Assay with Atomic Absorption Spectrometry finish (method GE_FAA30V5)..."

A lab technique that uses specific wavelengths of light to detect and measure tiny amounts of metal atoms in a sample, like using a tuned flashlight to make only certain metal particles glow so you can count them. Investors watch these results because they affect product safety, environmental compliance, mining grades and regulatory approvals; accurate measurements can change costs, liabilities and the value of companies tied to metals or contamination.

gravimetric finish technical

"re-assayed by 30 g Fire Assay with Gravimetric finish (method GO_FAG30V)..."

A gravimetric finish is a precise way of measuring the final weight of a product or material after processing or manufacturing. It ensures that the final amount meets exact standards, similar to weighing ingredients carefully in cooking. For investors, it indicates attention to quality control and consistency, which can impact a company's reputation and product reliability.

icp-ms technical

"sodium peroxide fusion ICP-AES/ICP-MS package (method GE_ICM91A50)..."

Inductively Coupled Plasma Mass Spectrometry (ICP-MS) is a scientific technique used to detect and measure very small amounts of metals and other elements in a sample. It works like a highly sensitive scanner, helping researchers identify the presence of specific materials with great accuracy. For investors, understanding ICP-MS is important because it highlights advanced methods used in industries such as mining, environmental testing, and manufacturing, influencing the valuation and risks of related companies.

qa/qc technical

"Sampling, Analytical Methods and QA/QC All drill core samples..."

QA/QC stands for Quality Assurance and Quality Control, processes used to ensure products or services meet certain standards. Think of it as a way to check that a product is safe and works properly before reaching consumers, similar to how a chef tastes food before serving it. For investors, strong QA/QC practices indicate a company's commitment to delivering reliable, high-quality offerings, reducing risks and building trust.

2025 Drilling Identifies ~600 Metres Of Mineralized Strike Length Along the Valkyrie Gold Trend; Final Assays Include 9.4 g/t Au Over 2.2 m (Incl. 27.9 g/t Au Over 0.7 m)

VANCOUVER, British Columbia, Feb. 25, 2026 (GLOBE NEWSWIRE) -- Foremost Clean Energy Ltd. (NASDAQ: FMST) (CSE: FAT) ("Foremost" or the "Company") is pleased to report the final assay results from its 2025 diamond drill program at its 100%-owned Jean Lake Gold-Lithium Property (“Jean Lake”) located near the historic mining centre of Snow Lake in Manitoba. The program consisted of 15 drill holes (see Figure 1) totaling 2,266 metres (see News Release dated December 8, 2025). Final assays returned high-grade near surface intercepts including 9.4 g/t Au over 2.2 metres from 48.0 metres (including 27.9 g/t Au over 0.7 metres) in JL25-010 and 6.2 g/t Au over 2.6 metres from 52.5 metres (including 31.1 g/t Au over 0.5 metres) in JL25-009 (see Table 1). These latest drill results continue to define and expand the near-surface gold system along the Valkyrie Trend. Gold mineralization has now been intersected along approximately 600 metres of strike length on and adjacent to the Valkyrie Trend (see Figure 2), significantly increasing the scale of the emerging gold system.

Highlights:

JL25-006

• 2.9 g/t Au over 6.7 m starting at 169.5 m, including 32.6 g/t Au over 0.5 m
• 2.6 g/t Au over 2.5 m starting at 36.0 m, including 6.2 g/t Au over 0.5 m

JL25-007

• 2.6 g/t Au over 5.4 m starting at 43.4 m, including 6.8 g/t Au over 1.8 m

JL25-009

• 6.2 g/t Au over 2.6 m starting at 52.5 m, including 31.1 g/t Au over 0.5 m
• 1.5 g/t Au over 9.1 m starting at 15.4 m, including 9.1 g/t Au over 0.9 m
• 1.6 g/t Au over 6.7 m starting at 30.0 m, including 9.2 g/t Au over 1.0 m

JL25-010

• 9.4 g/t Au over 2.2 m starting at 48.0 m, including 27.9 g/t Au over 0.7 m

Jason Barnard, Foremost’s President and CEO, commented: “These final results complete a successful 2025 drill campaign and significantly advance our understanding of the Jean Lake property. What began as a high-grade discovery in 2023 has now evolved into a ~600-metre mineralized gold corridor along the Valkyrie Gold Trend, characterized by consistent higher-grade zones within broader mineralized envelopes. Mineralization occurs at shallow depths in several holes and remains open along strike and at depth, reinforcing our confidence that this represents a robust shear zone gold system rather than isolated occurrences. Our next phase will focus on step-out and infill drilling to expand the corridor and further define and target the higher-grade components of this structurally controlled system.”

The Valkyrie Trend – An Emerging Gold Corridor

Gold mineralization at Jean Lake was first identified in discovery hole JL23-008 in 2023 (see News Release dated June 6, 2023), which returned 7.5 g/t Au over 7.66 metres including 102.0 g/t Au over 0.48 metres. Drill holes JL25-001 through JL25-004, previously reported on November 10, and 19, 2025, expanded the mineralized footprint and confirmed continuity along the Valkyrie Trend, including:

• JL25-001: 12.7 g/t Au over 2.07 m (including 40 g/t Au over 0.6 m)
• JL25-002: 10.7 g/t Au over 5.6 m (including 82 g/t Au over 0.7 m)
• JL25-003: 9.0 g/t Au over 3.5 m (including 34.2 g/t Au over 0.8 m)
  

The results from holes JL25-006 through JL25-015 further extend and define gold mineralization along the Valkyrie Trend. Gold mineralization has now been identified over approximately 600 metres of strike length (Figure 2). Gold mineralization is interpreted to be primarily hosted within a steeply dipping shear zone characterized by quartz veining and sericite alteration. Mineralized intercepts are characterized by broad (~5-7m) 1–3 g/t Au mineralized envelopes hosting higher-grade zones exceeding 20–80 g/t Au. Multiple drill fences between 2023 and 2025 on and adjacent to the Valkyrie Trend illustrate a robust gold system that remains open along strike and at depth.

Full assay results from the final 2025 drill holes and drill collar information are summarized in Table 1 and Table 2 below.

Next Steps

Building on the identification of mineralization across roughly 600 metres of strike length along the Valkyrie Trend, the Company intends to advance a focused follow-up program. This program will include step-out and infill drilling to test strike extensions beyond the currently defined limits and to target higher-grade zones within the broader mineralized corridor. Work will also continue to evaluate structural controls and lithological influences on gold distribution in order to refine drill targeting and guide the next phase of exploration.

Sampling, Analytical Methods and QA/QC

All drill core samples from the Jean Lake gold drilling program were collected as NQ-sized core. In zones of visible quartz-veining, sericite alteration, and arsenopyrite mineralization, samples were typically taken at 50 cm intervals. Outside of these zones, holes were continuously sampled at 1.5 m intervals. All core was sawn longitudinally, with one half retained on site for reference and the other half submitted for analysis. Samples were shipped to SGS Canada Inc., Burnaby, British Columbia, for sample preparation and analysis. At SGS, samples were dried at 105°C, crushed to 75% passing 2 mm, and pulverized to 85% passing 75 microns (method PRP89). Gold analyses were performed by 30 g Fire Assay with Atomic Absorption Spectrometry finish (method GE_FAA30V5) with a detection range of 5–10,000 ppb Au. Samples returning values above the upper detection limit were re-assayed by 30 g Fire Assay with Gravimetric finish (method GO_FAG30V) with a reporting range of 0.5–10,000 ppm Au. Multi-element geochemical analyses were completed using the 57-element sodium peroxide fusion ICP-AES/ICP-MS package (method GE_ICM91A50), which provides detection limits suitable for trace-level pathfinder elements such as As, Sb, and W relevant to gold mineralization. Analytical work was performed at SGS’s ISO/IEC 17025-accredited facilities, which operate under strict internal QA/QC protocols.

Quality control procedures at SGS include the routine insertion of blanks, certified reference materials (standards), and duplicates at a minimum frequency of 11–12% of all analyses, depending on method and grade classification. Laboratory quality is monitored through SGS’s SLIM Laboratory Information Management System, which automatically flags data exceeding internal precision or accuracy thresholds and triggers reanalysis when necessary. Foremost’s internal QA/QC protocol includes the insertion of field duplicates, certified standards, and blanks into the sample stream at regular intervals to independently monitor analytical precision and contamination. All reported intervals represent downhole lengths, and true thicknesses have not yet been determined.
