Silverco Mining Ltd. (TSXV: SICO) (‘Silverco’ or the ‘Company’) is pleased to announce a validated and updated Mineral Resource Estimate (‘MRE’) for its 100%-owned Cusi Project (‘Cusi’), located approximately 90 kilometres northwest of First Majestic’s Los Gatos Mine in Chihuahua, Mexico. The Updated Mineral Resource Estimate was completed by Ben Eggers MAIG, P.Geo., and Allan Armitage, Ph.D., P.Geo., of SGS Geological Services.

Highlights of the 2025 Cusi Mineral Resource Estimate:

• Substantial High-Grade Silver Inventory:
  • Measured & Indicated (‘M&I’) Resources: 4.89 million tonnes grading 262 g/t silver equivalent (‘AgEq’) containing 41.2 million ounces AgEq.
  • Inferred Resources: 4.07 million tonnes grading 243 g/t AgEq containing 31.8 million ounces AgEq.
• San Miguel Growth: The San Miguel Vein System has emerged as a significant growth driver, contributing 10.8 Moz AgEq (Indicated) and 16.2 Moz AgEq (Inferred) to the global resource, validating the Company’s focus on this new bulk-tonnage potential zone.
• Improved Geological Confidence: The updated model utilizes a tighter search radius for Inferred resources (reduced from 200m to 100m) and increased cut-off grades (increased from 95 g/t AgEq to 120 g/t AgEq), resulting in a more conservative and robust estimate focused on profitable ounces.
• Silver Primary Deposit: 86% of the value of the Updated Mineral Resource Estimate is comprised of silver.

Comparison to historical 2020 MRE:

The historical 2020 MRE hosted Measured & Indicated resources of 5.4Mt grading 215 g/t AgEq containing 37.0 Moz AgEq and Inferred resources of 4.9Mt grading 183 g/t AgEq containing 28.8 Moz AgEq. Since the historical 2020 MRE, approximately 0.81Mt of diluted resources grading 182 g/t AgEq containing 4.8 Moz AgEq were depleted through mining. Additionally, the impact of reducing the inferred search radius from 200m to 100m, resulted in a reduction of inferred resources of approximately 2.1 Mt containing 10.1 Moz AgEq. Accounting for these impacts, the 2025 updated MRE results in the following highlights:

• 28% increase in M&I resources, net of depletion, from 32.2 to 41.2 Moz AgEq
• 22% increase in M&I grade, from 215 to 262 g/t AgEq
• 9% increase in M&I tonnes, net of depletion, from 4.5Mt to 4.9Mt
• 70% increase in inferred resources, net of search reduction, from 18.7 to 31.8 Moz AgEq

Historical resources were reported at a 95 g/t AgEq cut-off grade for the historical 2020 MRE. Details of the estimate are provided in Sierra Metals November 18, 2020 press release and a NI 43-101 compliant technical report filed in December, 2020.​ The 2020 MRE is considered historical in nature, and Silverco is not treating the historical resources as current. The historical resources for the Cusi deposits are superseded by the 2025 Measured, Indicated and Inferred MRE for the deposits.

Mark Ayranto, CEO of Silverco, commented:

‘This validated and updated Mineral Resource Estimate represents a crucial step in our development of Cusi towards a restart decision. Our technical team has focused on quality over quantity, delivering a robust resource model that reduces internal waste and tightens estimation parameters to better reflect the potential of the deposit. While we have applied more conservative constraints than previous estimates, the grade profile remains exceptional at over 260 g/t AgEq in the Measured and Indicated categories.

‘Most importantly, this MRE confirms what our exploration success at San Miguel has been telling us. This zone now hosts a substantial portion of our resource and exhibits the widths and continuity required for more efficient bulk mining methods. With the system wide open, Cusi has a solid foundation of high-grade ounces and a clear path for continued expansion.

‘This MRE update only included a portion of our 2025 drilling, and recent results such as hole CU-25-37’s 8.8m of 319 g/t AgEq and 12.4m of 273 g/t AgEq have not been incorporated into this resource. We believe that the remainder of 2025’s drilling has already the potential to substantially add to this resource.’

Table 1: Cusi Project Underground Mineral Resource Estimate, October 20, 2025

Cusi Project Mineral Resource Estimate Notes:
(1) The mineral resource was estimated by Ben Eggers, MAIG, P.Geo. of SGS Geological Services, an independent Qualified Person as defined by NI 43-101. Eggers conducted a site visit to the Cusi Property on September 22-23, 2025. The mineral resource was peer reviewed by Allan Armitage, Ph.D., P.Geo. of SGS Geological Services, an independent Qualified Person as defined by NI 43-101.
(2) The classification of the Mineral Resource Estimate into Indicated and Inferred mineral resources is consistent with current 2014 CIM Definition Standards for Mineral Resources and Mineral Reserves. The effective date of the Cusi Project Mineral Resource Estimate (MRE) is October 20, 2025. This is the close out date for the final mineral resource drilling database.
(3) All figures are rounded to reflect the relative accuracy of the estimate and numbers may not add due to rounding.
(4) All mineral resources are presented undiluted and in situ, constrained by continuous 3D wireframe models (considered mineable shapes), and are considered to have reasonable prospects for eventual economic extraction. The mineral resource is exclusive of mined out material.
(5) Mineral resources are not mineral reserves. Mineral resources which are not mineral reserves, do not have demonstrated economic viability. An Inferred Mineral Resource has a lower level of confidence than that applying to an Indicated or Measured Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated or Measured Mineral Resources with continued exploration.
(6) The Cusi Project MRE is based on a validated database which includes data from 2,052 surface and underground drillholes totalling 360,237 m completed between 2006 and October 2025 and 21,522 channels totalling 48,786 m completed between 2013 and 2023. The resource database totals 105,585 assay intervals representing 119,756 m of drillhole data and 71,605 assay intervals representing 48,783 m of channel data.
(7) The mineral resource estimate is based on 63 three-dimensional (‘3D’) resource models representing epithermal veins which comprise the Cusi vein systems. 3D models of mined out areas were used to exclude mined out material from the current MRE.
(8) Grades for Ag, Au, Pb, and Zn are estimated for each mineralization domain using 1.5 m capped composites assigned to that domain. To generate grade within the blocks, the inverse distance squared (ID²) interpolation method was used for all domains.
(9) An average density value of 2.75 g/cm³ was assigned to all domains based on a database of 244 samples.
(10) It is envisioned that the Cusi Project deposits may be mined using underground mining methods. Mineral resources are reported at a base case cut-off grade of 120 g/t AgEq. The mineral resource grade blocks were quantified above the base case cut-off grade, below surface, within the constraining mineralized wireframes, and exclusive of mined out material.
(11) The underground base case cut-off grade of 120 g/t AgEq considers metal prices of US$30/oz Ag, US$2400/oz Au, US$1.00/lb Pb, and US$1.35/lb Zn and metal recoveries of 90% for Ag, 50% for Au, 90% for Pb, and 60% for Zn.
(12) The underground base case cut-off grade of 120 g/t AgEq considers a mining cost of US$60.00/t rock and a processing, treatment and refining, transportation and G&A cost of US$35.00/t mineralized material.
(13) The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.

Table 2: Cusi Project Underground Mineral Resource Estimate by Area, October 20, 2025

(1) The underground base case cut-off grade of 120 g/t AgEq considers metal prices of US$30/oz Ag, US$2400/oz Au, US$1.00/lb Pb, and US$1.35/lb Zn, metal recoveries of 90% for Ag, 50% for Au, 90% for Pb, and 60% for Zn, a mining cost of US$60.00/t rock, and a processing, treatment and refining, transportation and G&A cost of US$35.00/t mineralized material.

Table 3: Cusi Project Mineral Resource Estimate Sensitivity Table, October 20, 2025

(1) Underground mineral resources are reported at a base case cut-off grade of 120 g/t AgEq (highlighted). Values in this table reported above and below the base case cut-off grades should not be misconstrued with a Mineral Resource statement. The values are only presented to show the sensitivity of the block model estimate to the base case cut-off grade.
(2) All values are rounded to reflect the relative accuracy of the estimate and numbers may not add due to rounding.

NEW YORK (December 9, 2025) — via MiningNewsWire — LaFleur Minerals Inc. (CSE: LFLR) (OTCQB: LFLRF) (FSE: 3WK0) today announces its placement in an editorial published by MiningNewsWire (‘MNW’), one of 75+ brands within the Dynamic Brand Portfolio @ IBN ( InvestorBrandNetwork ) , a specialized communications platform with a focus on financial news and content distribution for private and public companies and the investment community.

To view the full publication, ‘Momentum Builds, Upside Appears as Mining Explorers Transition Toward Production, Unlock Major Hidden Value,’ please visit: https://ibn.fm/iBvlZ

The most compelling moment for investors to engage with a mining company is often during its transition from explorer to producer, a period when value can inflect sharply as an organization shifts from discovery to cash flow. Explorers that successfully cross this development threshold tend to realize significant re-ratings because they de-risk their story, demonstrate reliable production capability and create a foundation for recurring revenues. For many interested in the mining space, entering at this stage allows participation before the substantial upside typically associated with the first years of production is fully priced in.

This moment becomes particularly attractive when a company controls key infrastructure, is advancing toward production in a tier-one jurisdiction and trades at a valuation meaningfully below the replacement cost of its assets. That dynamic is now unfolding around LaFleur Minerals Inc., which owns a fully permitted and refurbished gold mill in Québec’s Abitibi region and is positioned well ahead of neighboring peers still working through early development stages. With a district-scale land position, an advancing flagship deposit and near-term production plans, LaFleur offers meaningful leverage to the explorer-to-producer inflection point, which historically delivers some of the best returns in the mining sector.

About LaFleur Minerals Inc.

LaFleur Minerals is focused on the development of district-scale gold projects in the Abitibi Gold Belt near Val-d’Or, Québec. The Company’s mission is to advance mining projects with a laser focus on our resource-stage Swanson Gold Project and the Beacon Gold Mill, which have significant potential to deliver long-term value. The Swanson Gold Project is approximately 18,304 hectares (183 km(2)) in size and includes several prospects rich in gold and critical metals previously held by Monarch Mining, Abcourt Mines, and Globex Mining. LaFleur has recently consolidated a large land package along a major structural break that hosts the Swanson, Bartec and Jolin gold deposits and several other showings which make up the Swanson Gold Project. The Swanson Gold Project is easily accessible by road allowing direct access to several nearby gold mills, further enhancing its development potential. LaFleur Minerals’ fully permitted and refurbished Beacon Gold Mill is capable of processing over 750 tonnes per day and is being considered for processing mineralized material from Swanson and for custom milling operations for other nearby gold projects.

(TheNewswire)

Vancouver, Canada, December 9, 2025 TheNewswire – Spartan Metals Corp. (‘ Spartan ‘ or the ‘ Company ‘) (TSX-V: W | OTCQB: SPRMF | FSE: J03) is pleased to announce the discovery of two new tungsten-silver-rubidium exploration targets at the Tungstonia deposit part of the company’s 100% owned Eagle Tungsten-Silver-Rubidium Project (‘ Eagle ‘ or ‘ Project ‘) in eastern Nevada.

Highlights:

• Soil samples taken provided near complete coverage of the original Tungstonia and Rees claim blocks on 100-meter (‘m’) x 100m grid totalling approximately 2,100 samples covering about 20 square kilometers (‘km ‘).

• Encouraging grades in soil at Tungstonia suggest near-surface mineralization included:

  • Tungsten up to 272 parts per million (‘ppm’) with 76 samples over 50 ppm

  • Silver up to 5.9 grams per tonne (‘g/t’) with 57 samples over 1.0 g/t

  • Rubidium up to 537 ppm with 56 samples over 300 ppm

• Discovered two new exploration targets:

  • Significant ~2.0 km x ~1.7 km anomaly outlined by coincident tungsten-silver-rubidium enrichment on western portion of Tungstonia claims that follows the same structural trends and spacings observed at the legacy past-producing Tungstonia mine approximately 1.5 km to northwest

  • Substantial ~0.75 km x ~2.1 km anomaly in southeast portion of Tungstonia claims trending southeast

Soil sample results from the 2025 surface geology program that commenced on October 16, 2025 , have outlined an approximate 2.0 km x 1.7 km surface anomaly that is aligned with regional trends observed at past-producing Tungstonia Mine and a second 0.75 km x 2.1 km surface anomaly in the southeast portion of the Tungstonia claims that confirm mapped veins and structured identified earlier this year. The soil results from the Rees block did not yield any new targets. The results of the soil sample program will help generate drill targets for a spring 2026 drill program.

Brett Marsh, Spartan’s President and CEO, states, ‘These soil results are very exciting as they validate our exploration model and generate important steps toward defining drill targets at Tungstonia. We initiated our surface exploration program with two key objectives; to extend the known veins at the legacy Tungstonia mine, and to define new veins in the western portion of the Tungstonia Claim block.  I believe the results of the hard work completed by our team has successfully met those objectives.’

Mr. Marsh continues, ‘The strength and extent of the anomalies — in some cases exceeding those observed around the past-producing Tungstonia mine — highlight the potential for a significantly larger mineral system than historically recognized. These new targets strengthen Spartan’s position within the U.S. critical minerals onshoring landscape. Our team is eager to continue working with our data to generate meaningful drill targets for a drill program in the spring of 2026.’

Tungsten in the soil samples at Tungstonia showing two anomalous zones. The Western Tungsten Anomaly is aligned with the north-northeasterly structural trend observed at the legacy Tungstonia mine. The Southeastern Tungsten Anomaly appears to coincide with intrusive contacts with carbonaceous sediments that could extend further to the southeast. Note that the soil results in these anomalies appears to be stronger than those obtained from the known Tungstonia mine area suggesting significant new exploration potential (Figure 1).

Silver in the soil samples at Tungstonia showing two anomalous zones coinciding with the tungsten anomalies shown in Figure 1. Note that the soil results in these anomalies appears to be stronger than those obtained from the known Tungstonia mine area suggesting significant new exploration potential (Figure 2).

Rubidium in the soil samples at Tungstonia showing two anomalous zones coinciding with the tungsten and silver anomalies shown in Figures 1 and 2 respectively. Note that the soil results in these anomalies appears to be stronger than those obtained from the known Tungstonia mine area suggesting significant new exploration potential (Figure 3).

Significance of Soil Results

Soil sampling is typically used at early stages of exploration to quickly identify geochemical anomalies that can indicate underlying mineralization, veins, favorable alteration, or to help understand geological controls such as, structural trends. Soils form from breakdown of underlying rock and higher grades (hundreds of parts per million or several grams per tonne) can be indicative of mineralization near the surface and increase confidence that the identified anomalies are genuine. Tungsten, silver, and rubidium at the Tungstonia claims show overlapping elevated values that are reasonably well aligned regional structural trends that control mineralization at the legacy Tungstonia mine, so the newly defined targets are potentially material and could be significant additions to the mineralization at the Tungstonia deposit.

Additionally, the soil results in these two anomalous areas appear to have a stronger signature that what was returned over the legacy past-producing Tungstonia mine area. This is potentially indicative of meaningful tungsten, silver, and rubidium mineralization in these large areas.

QA/QC Procedures

Samples were submitted to American Assay Lab (AAL) of Sparks, Nevada, which is a certified and accredited laboratory, independent of the Company. Samples are prepared using industry standard-prep methods and analyzed using method IO-4AB51 (51 element suite: 0.5g 4-acid plus boric acid hot block, ICP-OES plus IM-4ABEx ICP-MS for Rb. AAL undertakes its own internal coarse and pulp duplicate analysis to ensure proper sample preparation and equipment calibration. Spartan’s QAQC includes regular insertion of CRM standards, duplicates, and blanks with a stringent review of results completed by the Company’s Qualified Person, Brett R. Marsh, President and CEO of Spartan Metals.

About The Eagle Project

The Eagle Project presents a unique opportunity to delineate one of the largest and highest-grade Tungsten (‘W’) and Rubidium (‘Rb’) districts in the United States. The Project consists of the past-producing high-grade Tungstonia and Rees/Antelope tungsten (W-Cu-Ag) mines. Operations at these mines were from 1915 to 1942 with intermittent small-scale production occurring until 1956. Tungsten production from these two mines totaled 8,379 units at grades between 0.6%-0.9% WO 3 (1).

The Project is ~36.5 km² in size and located approximately 120 kilometers northeast of the town of Ely, in the Kern Mountains of White Pine County, Nevada. The Project covers 9,033 acres consisting of 445 Bureau of Land Management (BLM) unpatented lode mining claims.

Three deposit types are present at Eagle; Porphyry, Skarn, and Carbonate Replacement (CRD) that contain significant or anomalous grades of Tungsten (W), Silver (Ag), and Rubidium (Rb) plus Cu-Sb±Au-Pb-Zn-Bi-As across three project focus areas that also includes the potential to recover W-Rb-Ag from the legacy Tungstonia Mill Tailings.

Independent German Testing Firm Dorfner Anzaplan Confirms Multiple High-Value Markets Across Multiple Alternative Purification Routes

KEY HIGHLIGHTS:

• ULTRA-LOW STARTING IMPURITIES – CONFIRMING RAW WASHED SILICA QUALITY
  Homerun’s washed raw silica sand from its Santa Maria Eterna silica deposit (SME) in Belmonte, Bahia, Brazil analyzed via ICP contained exceptionally high SiO2 at 99.9694% and low impurities totalling 306 ppm including Fe (6.1 ppm), Al (8.9 ppm), Ti (33 ppm) and Na (4.1 ppm).
• MULTIPLE ALTERNATIVE PURIFICATION ROUTES WITHOUT HAZARDOUS CHEMICALS
  Testing validated multiple successful non-HF (hydrofluoric acid-free) purification processes that achieved 92-204 ppm total impurities, enabling Homerun to avoid the environmental and safety risks associated with traditional HF processing. The best result of 92 ppm total impurities was achieved through an innovative thermal treatment combined with caustic processing.
• QUALIFIED FOR PREMIUM SOLAR GLASS, OPTICAL GLASS AND INDUSTRIAL MARKETS
  Homerun’s SME silica sand tested positive for solar glass and extra clear glass applications which typically require iron impurities below 70 ppm. Homerun’s washed raw silica sand tested at less than 7 ppm. The Anzaplan processed silica exceeds specifications for Type I optical glass manufacturing, requiring iron below 1 ppm (Homerun SME silica sand achieved 0.34 ppm). Additional validated applications include engineered stone composites, fused silica, silicon carbide production and ceramics.

Homerun Resources Inc. (TSXV: HMR,OTC:HMRFF) (OTCQB: HMRFF) (‘Homerun’ or the ‘Company’) is pleased to announce exceptional results from comprehensive metallurgical testing completed by Dorfner Anzaplan GmbH, one of Europe’s leading independent silica sand testing laboratories based in Germany. The testing program evaluated multiple alternative purification routes for silica sand from Homerun’s Santa Maria Eterna silica sand resources in Belmonte, Bahia, Brazil (the ‘Belmonte Project’) confirming the deposit’s suitability for multiple high-value industrial applications.

As previously announced, Homerun has completed a 43-101 compliant Technical Report with Mineral Resource Estimate containing a preliminary resource of 25.56 Mt Measured and 38.35Mt Inferred of high-purity silica sand (>99.6% SiO2). This Mineral Resource Estimate is from only one of the three assets controlled by Homerun in the District.

Dorfner Anzaplan, a globally recognized authority in silica sand characterization and processing, received 25 kilograms of material from Homerun’s Belmonte Project in May 2025. The laboratory conducted an extensive evaluation of several alternative purification technologies specifically designed to avoid hydrofluoric acid, which is traditionally used in high-purity quartz processing but poses significant environmental and handling challenges.

The tested methods included:

• Caustic baking – high-temperature sodium hydroxide treatment
• Phosphoric acid baking – thermal treatment with phosphoric acid
• Caustic leaching – pressurized alkaline dissolution
• Calcination in combination with the above

All three methods successfully reduced impurity levels, with the most advanced treatment pathway, combining calcination at 1,400°C with caustic baking, achieving the best overall performance.

Brian Leeners, CEO of Homerun commented, ‘These results from Dorfner Anzaplan, one of the world’s most respected independent silica testing laboratories, validate what we’ve believed about our Belmonte Project, we have a world-class silica sand deposit with truly exceptional starting quality. The fact that we can achieve premium use-case specifications without hydrofluoric acid is a game-changer for project economics and environmental permitting. The exceptionally low iron and aluminum content is extraordinarily rare in global silica deposits. Aluminum and Iron are notoriously difficult to remove, so starting with such low levels gives us an inherent competitive advantage that cannot be replicated through processing alone. With multiple confirmed market pathways spanning solar glass, optical glass, engineered stone, silicon carbide, and industrial applications, we have significant optionality to optimize our product mix for maximum value. The global transition to renewable energy and electrification is driving unprecedented demand for high-purity silica, and the Belmonte Project is positioned to serve these growth markets with a superior environmental footprint.’

The raw, untreated silica sand from the Belmonte Project exhibited exceptionally low baseline impurities compared to typical global silica deposits:

‘The starting material quality is remarkable,’ noted the Dorfner Anzaplan report. ‘The material showed exceptionally low aluminum values’, a critical advantage since aluminum is one of the most difficult impurities to remove from silica sand.

Across all the purification processing methods tested, the Belmonte Project silica demonstrated exceptional response to impurity removal:

• Iron removal: reduced from 6.1 ppm to as low as 0.34 ppm (94% reduction)
• Titanium removal: reduced from 33 ppm to as low as 0.87 ppm (97% reduction)
• Aluminum stability: remained at industry-leading low levels throughout processing

The Dorfner Anzaplan team noted that iron and titanium removal performance exceeded even traditional HF leaching for certain treatment parameters, indicating that the crystal structure of Belmonte Project silica sand is particularly amenable to purification.

VALIDATED MARKET APPLICATIONS

Solar Glass – Premium Market Opportunity

Solar glass manufacturing, driven by the global solar energy boom, requires silica sand with iron content below 70 ppm. Homerun’s purified Belmonte Project silica achieved iron levels of 0.34 to 1.4 ppm – more than 50 times better than required specifications. The global solar glass market is projected to exceed $30 billion by 2030, driven by unprecedented solar panel installation demand worldwide. High-purity silica sand is the primary feedstock, with premium pricing commanded by materials that enable maximum light transmission.

Optical Glass – Type I Certification Quality

Optical glass for precision lenses, camera systems, scientific instruments, and telecommunications requires stringent impurity control. Type I optical glass specifications demand:

• Iron (Fe): <1 ppm
• Chromium (Cr): <0.05 ppm
• Manganese (Mn): <0.05 ppm
• Copper (Cu): <0.05 ppm

Homerun’s Belmonte Project silica met all Type I specifications across multiple purification tests, with best results showing 0.34 ppm iron and all other coloring elements below detection limits.

Dorfner Anzaplan’s technical evaluation confirmed Homerun’s silica is suitable for:

Silicon Carbide Production:

• Advanced material for semiconductors, electric vehicle power electronics, and high-temperature applications
• Requires >99% SiO2 purity
• Belmonte Project material exceeds specifications

Fused Silica Manufacturing:

• High-performance material for semiconductors, fiber optics, and aerospace
• Specification: >99.5% SiO2, <0.02% Fe2O3
• Belmonte Project silica qualified for this premium market

Engineered Stone Composites (Quartz Countertops):

• Requires >99.5% SiO2 with uniform color and minimal discolored particles
• Belmonte Project silica’s low iron and titanium content ensures bright, consistent appearance
• Global engineered stone market valued at $25+ billion annually

Sodium/Potassium Silicate Production:

• Industrial chemicals used in detergents, cement, coatings
• Specification: >99% SiO2, <0.02% Fe2O3
• Belmonte Project material qualified

Frac Sand (Oil & Gas Proppant):

• Hydraulic fracturing applications requiring high-strength, round silica grains
• Specification: >99% SiO2
• Belmonte Project material qualified

Foundry Sand (Metal Casting):

• High-temperature mold and core production for metal casting
• Belmonte Project material meets requirements

ENVIRONMENTAL ADVANTAGE – NON-HF PROCESSING

A significant finding from the Dorfner Anzaplan testing program is that Homerun’s Belmonte Project silica can be successfully purified without hydrofluoric acid (HF), one of the most hazardous industrial chemicals. Traditional high-purity quartz processing relies heavily on HF, which poses:

• Severe environmental risks (groundwater contamination, atmospheric emissions)
• Extreme worker safety hazards (HF exposure can be fatal)
• Regulatory permitting challenges in many jurisdictions
• High insurance and liability costs
• Community opposition to operations

Homerun’s validation of phosphoric acid baking, caustic baking, and with further chemical and thermal treatment pathways provides multiple environmentally superior processing options. This differentiates the Belmonte Project from competing silica projects that require HF treatment to achieve comparable purity levels.

‘The successful demonstration of non-HF purification routes represents a significant competitive advantage,’ commented Homerun’s COO, Armando Farhate. ‘These results demonstrate Homerun’s ability to deliver high-purity silica products to premium markets while maintaining industry-leading environmental and safety standards.’
