Copper One Completes Third Hole of 2026 Phase 2 Drill Program (MHB-41) at Flagship Majuba Hill Copper Project, Nevada
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
Copper One Resources (CEXYF) completed MHB-41, the third hole of its 2026 Phase 2 drilling program at Majuba Hill in Nevada. The hole reached 1,850 feet (564 metres), bringing completed drilling across three Phase 2 holes to 4,925 feet (1,501 metres).
Preliminary core logging identified silicification, or silica alteration, with pyrite and chalcopyrite, tourmaline breccia—fragmented rock—and fracture coatings of hematite and tenorite. These visual observations do not establish metal grades or economic mineralization; no MHB-41 laboratory assay results are reported.
The expanded program comprises up to 10,000 feet (3,048 metres), with approximately 5,000 feet (1,524 metres) initially contracted to Evolve Exploration Nevada. Copper One intends the program to test priority targets and support advancement toward an inaugural mineral resource estimate under NI 43-101, Canada's mineral-project disclosure standard.
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, BC – November 13, 2026 – TheNewswire - Copper One Resources Corp. (“Copper One”) (CSE: CEXY | OTCID: CEXYF | FSE: IW8 | WKN: A42AGR) (the “Company”) announces the completion of drill hole MHB-41, the third hole of its 2026 Phase 2 diamond drilling program of up to 10,000 feet at its
MHB-41 reached a final downhole depth of 1,850 feet (564 metres). Preliminary geological core logging identified pervasive silicification with fine-grained pyrite and chalcopyrite, tourmaline breccia at multiple depths, and fracture coatings of hematite and tenorite. These observations provide additional geological information to support the Company’s ongoing evaluation of alteration and mineralization at Majuba Hill.
MHB-41 Highlights
-
Hole orientation and depth: MHB-41 was drilled on a grid azimuth of 075° at an inclination of −50°, reaching a final downhole depth of 1,850 feet (564 metres).
-
Silicification and sulfides: Core at approximately 580–581 feet pervasive silicification with fine-grained pyrite and chalcopyrite.
-
Tourmaline breccia: Selected core photographs show tourmaline breccia within core-box intervals of 808.0–817.6 feet and 1,066.7–1,076.3 feet, including angular, pale-coloured clasts within a dark matrix.
-
Fracture mineralization: Core at 1,261 feet (384 metres) downhole displays fracture coatings of hematite and tenorite.
-
Phase 2 drilling to date: MHB-39, MHB-40 and MHB-41 account for a combined 4,925 feet (1,501 metres) of completed diamond drilling.
All depths are downhole. The intervals cited for the tourmaline breccia photographs represent full core-box intervals and do not establish continuous mineralized widths. Mineral identifications are preliminary field observations. Visual observations do not determine metal grades or establish economic mineralization and should not be considered a substitute for laboratory assay results.
No laboratory assay results from MHB-41 are being reported in this news release. Any material analytical results will be disclosed following receipt, quality assurance/quality control review and evaluation by the Company's Qualified Person.

Forward-Looking Information
This news release contains certain “forward-looking information” and “forward-looking statements” within the meaning of applicable Canadian securities legislation (collectively, “forward-looking statements”). Forward-looking statements are generally identified by words such as “anticipates,” “believes,” “expects,” “intends,” “plans,” “estimates,” “may,” “will,” “could,” “potential,” and similar expressions.
Forward-looking statements in this news release include, but are not limited to, statements regarding the potential geological significance and interpretation of preliminary observations from drill hole MHB-41, including silicification, visually identified sulfide minerals, tourmaline breccia and fracture coatings preliminarily interpreted as hematite and tenorite; the potential presence, extent and continuity of copper-silver-gold mineralization at Majuba Hill; the anticipated receipt and interpretation of laboratory assay results; the identification, prioritization and testing of additional exploration targets; the anticipated scope, timing and completion of the Company's Phase 2 drilling program; the expected use and potential benefits of the EVX Connect platform; and the Company's objective of advancing the Majuba Hill Project toward an inaugural mineral resource estimate prepared in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects.
These forward-looking statements are based on management's current expectations, estimates, assumptions and projections as of the date of this news release. Material assumptions underlying such statements include, without limitation, the continued availability of drilling equipment, qualified personnel, contractors, laboratory services, supplies, permits and financing on acceptable terms; the Company's ability to maintain site access and conduct exploration activities without material disruption from weather or operating conditions; the progression of drilling operations substantially as contemplated; the timely receipt, review and interpretation of geological information and laboratory assay results; the reliability of historical exploration information; the continued support of the Company's geological interpretations and exploration targets through additional technical information; the validity and maintenance of mineral property tenure; and the availability of sufficient technical and financial resources to undertake future exploration programs and technical studies.
Actual exploration results may differ materially from management's expectations. Preliminary visual mineral identifications and geological interpretations may not be confirmed by subsequent laboratory analysis, mineralogical testing or additional geological work. Observed alteration, sulfide mineralization and breccia zones may not be continuous or associated with economically significant mineralization. Laboratory assay results may differ materially from preliminary visual observations, and additional drilling may fail to identify mineralization of sufficient grade, extent or continuity to support the delineation of a mineral resource.
Additional risks and uncertainties include drilling and assay delays; geological complexity and changes in geological interpretations; the accuracy, completeness and reliability of historical geological and exploration information; permitting and regulatory requirements; the validity and maintenance of mineral property tenure; the availability of financing, contractors, qualified personnel and equipment; equipment performance and operational challenges; adverse weather and site conditions; fluctuations in commodity prices; changes in general economic and market conditions; and the possibility that future exploration and technical studies may not substantiate current geological interpretations or support the preparation of a mineral resource estimate.
No mineral resource or mineral reserve has been established at the Majuba Hill Project, and there can be no assurance that ongoing or future exploration activities will result in the definition of a mineral resource or mineral reserve. Additional risk factors are described in the Company's continuous disclosure filings available under its profile on SEDAR+ at www.sedarplus.ca.
There can be no assurance that forward-looking statements will prove accurate, as actual results and future events may differ materially from those anticipated. Readers are cautioned not to place undue reliance on forward-looking statements. Except as required by applicable securities laws, the Company undertakes no obligation to update or revise any forward-looking statements as a result of new information, future events or otherwise.
