Barksdale Commences Updated PEA for San Javier Copper-Gold Project, Adding Gold for the First Time and Current Consensus Metal Pricing
The earlier copper-only assessment assigned no value to gold; the update will test recovery and reassess project economics.
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
Barksdale Resources (BRKCF) has begun updating the preliminary economic assessment for its wholly owned San Javier copper-gold project in Mexico. The update will evaluate gold recovery for the first time and use consensus long-term copper and gold prices. Barksdale expects completion in the fourth quarter of 2027.
The 2024 assessment used US$4.00/lb copper, with initial capital of US$116.8 million and post-tax net present value of US$61.6 million at a 7% discount rate. The update covers recovery testing, a copper-gold resource estimate, pit optimization and revised costs and economics. Gold assays from 187 samples returned positive results in four of five historical drill holes. The previously cited 250,000–400,000 ounces of gold is conceptual, not a defined mineral resource; further work may not establish one.
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 28, 2026) - Barksdale Resources Corp. (TSXV: BRO) (OTCQB: BRKCF) (FSE: 2NZ) ("Barksdale" or the "Company") is pleased to announce that it has commenced an update (the "PEA Update") to the Preliminary Economic Assessment for its
Highlights
Gold focus: The PEA Update will include additional metallurgical testing to focus on the recovery of gold and copper mineralization and its potential impact on Project economics. Gold occurs primarily in the surficial oxide zone, with intercepts including 15.0 metres of 0.727 g/t Au in SJ21-25 beginning 21.0 metres below surface.
2026 gold assays: In 2026, the Company assayed 187 drill core reject samples from five holes drilled in 2007 for gold content. Four of the five holes returned positive results, including 9.0 metres of 3.464 g/t Au in SJ07-64 and 12.0 metres of 1.084 g/t Au in SJ07-66.
2024 PEA mine plan: Life-of-mine strip ratio of 0.6:1. As the mineralization outcrops at surface, minimal pre-stripping would be required, and waste material would be used as fill for construction and haul roads.
Consensus pricing: Updated metal prices for copper and gold will replace the 2024 PEA's US
$4.00 /lb copper-only price deck.Pit shell optimization: Higher copper prices and potential gold credits will be evaluated to determine whether the conceptual pit shell can be extended below the base of the hill, where mineralization continues at depth.
Copper price sensitivity (2024 PEA): In the 2024 PEA, US
$4.50 /lb copper increased the Measured and Indicated tonnage by18% and post-tax NPV7% by68% , without gold.Timing: The PEA Update is expected to be completed in the fourth quarter of 2027.
Chris Stewart, President and Chief Executive Officer of Barksdale, stated: "The San Javier Project is an exciting opportunity given its low initial capital cost of US
The potential quantity of gold referenced above is conceptual in nature. It was reported in Section 24.3 of the 2024 PEA based on gold grades estimated in the copper block model, and no evaluation was completed of how the gold relates geometrically to the copper mineralization. There has been insufficient exploration to define a gold Mineral Resource, and it is uncertain if further work will result in the gold mineralization being delineated as a Mineral Resource.
2024 PEA Summary
The Cerro Verde deposit at San Javier forms a hill rising to 300 metres above the plain and foothills to the west. Mineralization outcrops at surface and the oxide zone averages approximately 150 metres thick, reaching up to 200 metres at the summit. The 2024 PEA mine plan contemplates mining the hill from the top down, with minimal pre-stripping and a life-of-mine strip ratio of 0.6:1 (waste to mineralized material). Pre-strip material would be used as fill for construction and haul roads.
The 2024 PEA outlined an open pit, heap leach and solvent extraction-electrowinning (SX-EW) operation producing copper cathode at 10,000 tonnes per day over a 12-year mine life, with initial capital of US
Copper and gold prices have risen substantially since the 2024 PEA. Consistent with peer copper and copper-gold developers, the PEA Update will use consensus long-term prices.
Gold at San Javier
San Javier has characteristics of iron oxide copper-gold (IOCG) deposits. Gold was not included in the 2022 Mineral Resource estimate or the 2024 PEA because no work had been completed to evaluate its economic extraction, and the 2024 PEA recommended that the Company evaluate the potential for a gold Mineral Resource. The Company has since assayed 187 preserved drill core reject samples for gold (see news release dated July 30, 2026) and is selecting 2007 and 2021 drill core rejects for bottle roll and column leach tests to estimate gold recoveries.
Scope of the PEA Update
AKF Mining Services will complete the PEA Update in accordance with NI 43-101, including:
Updated gold and silver metallurgical test work and recovery assumptions;
An updated copper and gold Mineral Resource estimate at consensus pricing;
Re-optimization of the pit shell and cut-off grades; and
Updated capital and operating costs, mine plan and economic analysis including copper and gold.
Cautionary Statements
The 2024 PEA is preliminary in nature and includes Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves, and there is no certainty that the 2024 PEA or the PEA Update will be realized. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. The sensitivity cases described in this news release are taken from the 2024 PEA and are not a new Mineral Resource estimate or economic analysis. The results of the PEA Update, including any change to the Mineral Resource, cut-off grades or Project economics, are not yet known and may differ materially from the 2024 PEA and from the sensitivity cases presented.
The 2024 PEA did not estimate a gold Mineral Resource. The 250,000-to-400,000-ounce range of gold mineralization reported in the 2024 PEA is conceptual in nature and is not a Mineral Resource. No gold Mineral Resource has been defined at San Javier, and there is no certainty that the PEA Update will result in a gold Mineral Resource or that gold will be economically recoverable.

FAQ
AI-generated questions and answers. How Rhea-AI works. Not financial advice.
When does Barksdale expect to complete the San Javier assessment update?
Barksdale expects the San Javier preliminary economic assessment update to be completed in the fourth quarter of 2027. It will evaluate copper and gold economics using consensus long-term metal prices.
Does Barksdale have a defined gold mineral resource at San Javier?
San Javier does not have a defined gold mineral resource. The conceptual quantity of 250,000 to 400,000 ounces came from gold grades estimated in the copper block model. Exploration has been insufficient to define a gold resource, and further work may not establish one.
How will Barksdale test gold recovery for the San Javier update?
Barksdale is selecting 2007 and 2021 drill core rejects for bottle roll and column leach tests to estimate gold recoveries. AKF Mining Services will complete the assessment update, whose scope includes updated gold and silver metallurgical testing and recovery assumptions.
