Second Government Critical Mineral Study Begins at Bell Copper's Big Sandy Porphyry Copper Project in Arizona, USA
Bell Copper (OTCQB: BCUFF) announced that the Arizona Geological Survey at the University of Arizona, funded by the U.S. Geological Survey and the State of Arizona, has begun a new study at the Big Sandy porphyry copper project to assess potential critical mineral resources.
Bell is contributing drill core samples; initial systematic sampling of the supergene profile is complete. Big Sandy core records a continuous transition from leached capping to supergene blanket and contains copper, rhenium, and silver, all on the USGS 2025 Draft List of Critical Minerals. A prior University of Arizona thesis supports a genetic link to the Diamond Joe pluton 13 km west.
Bell is seeking funding to resume and complete drilling of BS-4 (suspended August 2024), planned to reach bedrock with rotatory drilling followed by coring; BS-3 previously intersected 200 m of chalcocite-bearing porphyry.

Bell sta fornendo campioni di core di trivellazione; l'analisi sistematica iniziale del profilo supergene è completa. Il core di Big Sandy registra una transizione continua dalla copertura detritica (leached) alla coperta supergene e contiene rame, rhenio e argento, tutti presenti nell'Elenco Draft 2025 dei Minerali Critici della USGS. Una tesi precedente dell'Università dell'Arizona sostiene un legame genetico con il plutone Diamond Joe a 13 km a ovest.
Bell sta cercando finanziamenti per riprendere e completare le trivellazioni di BS-4 (sospeso agosto 2024), previsto raggiungere la litologia di base con trivellazione rotativa seguita da carotaggio; BS-3 aveva precedentemente incontrato 200 m di porfirio contenente calcoscita.

벨 코퍼(BELL Copper) (OTCQB: BCUFF)은 애리조나 대학교 지질조사(Survey)가 미국 지질조사국(USGS)과 애리조나 주의 자금 지원으로 새로운 연구를 시작했다고 발표했습니다. 연구 대상은 Big Sandy 포르피릭 구리 프로젝트로, 잠재적인 핵심 광물 자원을 평가하기 위한 것입니다.
벨은 시추 코어 샘플을 제공하고 있으며, 상부 표면(supergene) 프로파일의 초기 체계적 샘플링은 완료되었습니다. Big Sandy 코어는 구리, 레니움, 은을 포함하고 있으며, 이는 모두 USGS 2025년 초안의 핵심 광물 목록에 등재되어 있습니다. 애리조나 대학의 이전 논문은 Diamond Joe 화강암에서 서쪽으로 13km 떨어진 곳과의 발생적 연계를 지지합니다.
벨은 BS-4의 재개와 완료를 위한 자금을 찾고 있으며, 2024년 8월에 중단된 이 시추를 재개할 예정입니다. 로터리 시추로 기반암에 도달한 뒤 코어링을 계획하고 있으며, BS-3는 이전에 200 m의 칼코사이트 함유 포르피를 교차했습니다.

Bell liefert Bohrkernproben; die anfängliche systematische Probenahme des Supergene-Profils ist abgeschlossen. Der Big Sandy-Kern zeigt einen kontinuierlichen Übergang von auslaugender Deckschicht zu Supergene-Decke und enthält Kupfer, Rhenium und Silber, die alle auf der USGS Draft-Liste der kritischen Mineralien 2025 stehen. Eine frühere Universität von Arizona-Arbeit unterstützt eine genetische Verbindung zum Diamond Joe-Pluton 13 km westlich.
Bell sucht nach Mitteln, um das Bohren von BS-4 (im August 2024 pausiert) wieder aufzunehmen und abzuschließen, geplant ist, bis zur Grundgesteinsschicht mit rotierndem Bohren vorzudringen, gefolgt von Bohrkernen; BS-3 hat zuvor 200 m porphyrisches Gestein mit Chalkopyrit durchbohrt.

Vancouver, British Columbia--(Newsfile Corp. - October 17, 2025) - Bell Copper Corporation (TSXV: BCU) (OTCQB: BCUFF) ("Bell Copper" or the "Company") reports that the Arizona Geological Survey at the University of Arizona, with funding from the United States Geological Survey and the State of Arizona, has initiated a new study at the Company's Big Sandy porphyry copper discovery to assess potential new resources of critical minerals in Arizona. The Company is contributing core samples from its
- Several critical minerals are commonly enriched in deposits like Big Sandy
- Big Sandy core records the continuous transition from leached capping to supergene blanket
- Initial Samples have been contributed from the Company's drill core
The Arizona Geological Survey ("AZGS") research initiative, led by Dr. Carson Richardson, Senior Research Scientist, and Ms. Zoey Plonka, AZGS Research Scientist, is a two-pronged project with one component focused on constraining both the timing of exhumation (via thermochronology) and supergene processes (via Ar-Ar geochronology of alunite and jarosite). The other component would include a detailed study of the Big Sandy supergene profile using systematic sampling to quantify elemental/critical mineral presence and variability. This sampling work has now been completed.
A previous study of Big Sandy core samples culminated in the publication of a University of Arizona Master's Thesis entitled "Integrating Geochronology and Ore Mineralogy Constraints to Correlate the Formation of the Diamond Joe Pluton and Big Sandy Porphyry Copper Prospect, NW Arizona, USA" by Jonothan Chappell, generally supporting the Company's concept of a genetic link between the Big Sandy porphyry and the root zone at Diamond Joe Peak, 13 kilometers to the west.
The Big Sandy core has been demonstrated to contain significant amounts of copper, rhenium, and silver, elements which, notably, the U.S.G.S. included on its 2025 Draft List of Critical Minerals.
Dr. Timothy Marsh, Bell's President and CEO, and a Qualified Person as defined by NI43-101, said,
"Bell is pleased to contribute further samples of the Big Sandy core to aid this assessment of the nation's critical mineral resources. Big Sandy's status as one of the few complete profiles from leached capping through supergene enrichment in an unmined porphyry copper deposit gives the AZGS a great example to study."
Bell Copper continues the work of securing funding to complete the drilling of BS-4 at Big Sandy, which was suspended in August 2024. The BS-4 drill hole is located 900 meters from the previous drill hole, BS-3, which had an intersection of 200 meters of chalcocite-bearing porphyry (see June 7, 2022 news). The Company plans to drill BS-4 into bedrock using an angle capable mud rotary drill, to be followed by coring into bedrock.
