Homerun Resources Inc. Receives US$19.6-27.6 Million AACE Class 5 CAPEX Estimate for Modular 4N Silica Purification Plant
The lower-cost configuration excludes the owner-supplied thermal storage system and requires further integration validation.
Sentiment and the balance of points
Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.
Rhea-AI Summary
Homerun Resources (HMRFF) received a conceptual capital-cost estimate of US$19.6–27.6 million for its planned modular high-purity silica plant in Brazil. Dorfner ANZAPLAN evaluated two configurations targeting approximately 30,000 tonnes per year of 4N silica, based on laboratory-scale testing. Dedicated calcination is estimated at US$27.6 million; integration with ENDURING thermal energy storage is estimated at US$19.6 million, excluding the owner-supplied storage system.
The estimated US$8.0 million plant-scope saving depends on successful integration and further validation. The estimate's expected accuracy range is approximately minus 30% to plus 50%. The module would complement a planned 3N plant with minimum capacity of 350,000 tonnes annually; combined plant capital costs are approximately US$29.0–37.0 million. Homerun plans further customer qualification, configuration selection and financing work, with early earthworks subject to approvals.
How this balance works
Rhea-AI gives every point it takes from this document a weight. Minor counts 1, Moderate 3 and Major 9, so one Major point outweighs several Minor ones. The bar adds up the weights on each side, and when neither side holds more than 65% of the total the balance reads Mixed.
It reads the document as published, with the same rules for every company, and it does not look at what the market expected or at how the stock traded, so a point can be objectively good on a day the stock falls.
Rhea-AI Sentiment measures something else, the tone of the wording.

Vancouver, British Columbia--(Newsfile Corp. - October 27, 2026) - Homerun Resources Inc. (TSXV: HMR) (OTCQB: HMRFF) ("Homerun" or the "Company") is pleased to announce that it has received the final AACE Class 5 capital expenditure ("CAPEX") estimate prepared by Dorfner ANZAPLAN GmbH ("ANZAPLAN") for the Company's planned modular 4N high-purity silica purification plant in the Santa Maria Eterna ("SME") silica sand district, Belmonte, Bahia, Brazil.
The ANZAPLAN study provides a conceptual engineering basis, including process design criteria, mass balance, block flow diagrams, major equipment list and a capital-cost estimate for the planned 4N purification module. The study builds on ANZAPLAN laboratory-scale test work for the most capital-intensive process flow corresponding to 4N2 (
Two CAPEX Configurations
ANZAPLAN evaluated two alternative configurations for Homerun's planned 4N purification plant. Both configurations incorporate the same downstream chemical purification circuit, including hydrofluoric acid leaching, hydrochloric acid washing, deionized-water rinsing, filtration, dewatering and drying.
Option 1: Dedicated Calcination - A dedicated electrically heated calcination and cooling system integrated with the 4N purification plant. CAPEX of US
Option 2: ENDURING TES Integration - Thermally treated silica sand supplied from Homerun's owner-supplied ENDURING TES system, followed by the common downstream purification circuit. CAPEX of US
The approximately US
The AACE Class 5 estimate is based on conceptual-level engineering, budgetary vendor quotations, historical equipment costs and engineering allowances. The report identifies an expected accuracy range of approximately minus
Integrated 3N and 4N Pathway
The completed 4N CAPEX study is a key capital-planning deliverable for Homerun's integrated silica-purification strategy. The Company's planned Phase 1 3N purification plant is designed for a minimum capacity of 350,000 tonnes per annum, creating the upstream silica feedstock for the modular 4N purification facility for purification into higher-value silica streams.
Homerun now has a defined capital framework for the 2N and planned 3N and 4N stages of its silica-purification strategy:
2N Processing Plant - No CAPEX - Processing provided under the Homerun/Jundu commercial district-level partnership for the extraction, processing of industrial grade silica sand from the Santa Maria Eterna silica district.
3N Purification Plant - Minimum 350,000 tonnes per annum, previously announced CAPEX: US
Modular 4N Purification Plant: Option 1, AACE Class 5 estimate: US
Modular 4N Purification Plant: Option 2, AACE Class 5 estimate: US
This staged approach provides Homerun with immediate industrial silica sales capacity and a scalable purification platform capable of producing 3N silica as an upstream base and subsequently upgrading selected feedstock to 4N silica for commercial sales and potential further processing into advanced silica materials.
Brian Leeners, CEO of Homerun, stated:
"Receipt of ANZAPLAN's 4N CAPEX estimate is an important execution milestone for Homerun. We now have a defined process pathway across all 3 stages of purification, 2N supported by the current Jundu plant, and conceptual engineering, process design, mass-balance work, equipment definition and capital-cost estimates for the 3N and 4N Plants. The conventional 4N configuration provides an independent, dedicated calcination pathway, while the ENDURING-integrated 4N configuration highlights the potential capital efficiency of incorporating our thermal energy storage platform into the silica purification value chain based on the work previously done with NLR, previously NREL (US Department of Energy). This work gives us a clear picture of the capital requirements for our planned 3N and 4N plants and supports our phased purification development strategy in the Silica Valley of Bahia. As we continue technical optimization and selection of the preferred configuration, Homerun is advancing the permitting process for the planned facilities and preparing to proceed with early earthworks, subject to the required approvals."
ENDURING Integration
The ENDURING-integrated option is designed to receive thermally treated silica sand from Homerun's owner-supplied ENDURING TES system. Under this configuration, the ENDURING system would provide the thermal treatment required ahead of chemical purification, eliminating the need to include a dedicated calcination and cooling circuit within the 4N purification plant estimate.
ANZAPLAN identifies the ENDURING-integrated option as the lower-CAPEX configuration. However, the study also identifies further work required to confirm the detailed system interface, operating performance, material handling, potential contamination risk, product quality and broader implementation requirements before a final configuration is selected.
Next Steps
With the 4N CAPEX estimate now completed, Homerun's next steps are expected to focus on: (i) completion of the review of the pilot-scale and bulk-sample test work already undertaken, (ii) continued customer sample qualification work following delivery of the 4N bulk sample, (iii) selection of the preferred 4N purification plant configuration, including the determination of the role of the ENDURING TES system, (iv) advancement of the financing approach and capital structure for the staged 3N and 4N plant development, and (v) continued permitting and site-preparation planning to support early earthworks at Santa Maria Eterna, subject to applicable approvals.
Further updates are expected as Homerun progresses configuration selection, customer qualification, financing strategy, and the engineering steps required to advance the project toward implementation.
4N Silica Market Context
4N silica is a high-purity material suited for value-added downstream applications including fused silica, specialty glass and glass core substrates, electronics fillers, upgraded metallurgical-grade silicon, and other advanced silica-material markets that require tight impurity control and consistent product quality. Homerun believes these end markets may support pricing materially above industrial-grade silica products, although the Company has not yet published an economic assessment for the planned 4N product stream.
As the project advances through customer qualification, engineering and commercial development, Homerun may provide additional guidance on target end markets, product positioning and economic parameters for the 4N silica module.
