Cosa Resources Reports Uranium Assays from the 100% Owned Ursa Project, Athabasca Basin, Saskatchewan
Cosa Resources has reported uranium assay results from its fall drilling program at the 100% owned Ursa Project in Saskatchewan's Athabasca Basin. The key finding was uranium mineralization in drill hole UR24-06, which yielded 0.22% U3O8 over 0.7 metres, marking the strongest and widest intersection to date on the project. The mineralization was found between 1087.8 and 1116.8 metres, with the strongest concentration occurring between 1088.6 and 1089.3 metres in weakly graphitic and pyritic pelitic gneiss.
The company's use of Ambient Noise Tomography (ANT) surveys to prioritize conductive strike has proven successful, producing significant results in their first ANT target drill hole. With only 21 drill holes completed within the 65-kilometre-long Project, Ursa remains largely underexplored with potential for multiple tier-1 deposits.
Cosa Resources ha riportato i risultati delle analisi di uranio dal suo programma di perforazione autunnale presso il progetto Ursa, di proprietà al 100% situato nel bacino di Athabasca in Saskatchewan. La scoperta chiave è stata la mineralizzazione di uranio nel foro di perforazione UR24-06, che ha restituito 0,22% U3O8 su 0,7 metri, segnando l'intersezione più forte e larga fino ad oggi nel progetto. La mineralizzazione è stata trovata tra 1087,8 e 1116,8 metri, con la maggiore concentrazione che si verifica tra 1088,6 e 1089,3 metri in gneiss pelitico debolmente grafitico e pirico.
L'uso da parte dell'azienda di sondaggi di Tomografia del Rumore Ambientale (ANT) per dare priorità ai colpi conduttivi si è rivelato vincente, producendo risultati significativi nel primo foro di perforazione target ANT. Con solo 21 fori di perforazione completati all'interno del progetto lungo 65 chilometri, Ursa rimane in gran parte inesplorato con potenziale per più depositi di livello 1.
Cosa Resources ha informado sobre los resultados de análisis de uranio de su programa de perforación de otoño en el Proyecto Ursa, de propiedad 100% en la cuenca de Athabasca, Saskatchewan. El hallazgo clave fue la mineralización de uranio en el pozo de perforación UR24-06, que arrojó 0,22% U3O8 en 0,7 metros, marcando la intersección más fuerte y ancha hasta la fecha en el proyecto. La mineralización se encontró entre 1087,8 y 1116,8 metros, con la mayor concentración ocurriendo entre 1088,6 y 1089,3 metros en gneis pelítico débilmente grafítico y pirítico.
El uso de la compañía de encuestas de Tomografía de Ruido Ambiental (ANT) para priorizar las estructuras conductivas ha demostrado ser exitoso, produciendo resultados significativos en su primer pozo de perforación objetivo ANT. Con solo 21 pozos perforados dentro del Proyecto de 65 kilómetros de longitud, Ursa sigue siendo en gran parte inexplorado, con potencial para múltiples depósitos de primera categoría.
Cosa Resources는 사스캐처원의 아사바스카 분지에 있는 100% 소유 Ursa 프로젝트의 가을 시추 프로그램에서 우라늄 분석 결과를 보고했습니다. 주요 발견은 시추 홀 UR24-06에서 우라늄 광물이 발견된 것으로, 0.22% U3O8를 0.7미터에 걸쳐 나타냈으며, 이는 현재 프로젝트에서 가장 강하고 넓은 교차점을 기록한 것입니다. 광물화는 1087.8미터에서 1116.8미터 사이에서 발견되었으며, 가장 강한 농도는 약한 그래파이트와 피라이트가 포함된 펠리틱 편암 사이의 1088.6미터와 1089.3미터에서 발생했습니다.
회사는 환경 소음 탐사(ANT) 조사를 통해 전도성 스트라이크를 우선시하는 데 성공했으며, 첫 번째 ANT 목표 시추 홀에서 중요한 결과를 도출했습니다. 65킬로미터 길이의 프로젝트 내에서 단 21개의 시추 홀만 완공된 Ursa는 여전히 탐사가 부족하며, 다수의 일급 매장지 가능성이 있습니다.
Cosa Resources a rapporté les résultats des analyses d'uranium de son programme de forage d'automne au projet Ursa, entièrement détenu, situé dans le bassin d'Athabasca en Saskatchewan. La découverte clé était la minéralisation d'uranium dans le trou de forage UR24-06, qui a donné 0,22% U3O8 sur 0,7 mètres, marquant la plus forte et la plus large intersection à ce jour dans le projet. La minéralisation a été trouvée entre 1087,8 et 1116,8 mètres, avec la concentration la plus forte se produisant entre 1088,6 et 1089,3 mètres dans du gneiss pelitique faiblement graphitique et pyritique.
L'utilisation par l'entreprise des enquêtes de Tomographie du Bruit Ambiant (ANT) pour prioriser les structures conductrices s'est révélée fructueuse, produisant des résultats significatifs dans son premier trou de forage cible ANT. Avec seulement 21 trous de forage complétés dans ce projet de 65 kilomètres de long, Ursa reste largement inexploré, avec un potentiel pour plusieurs dépôts de premier ordre.
Cosa Resources hat die Urananalysenergebnisse aus seinem Herbstbohrprogramm im 100%-Eigentumsprojekt Ursa im Athabasca-Becken in Saskatchewan veröffentlicht. Eine der wichtigsten Entdeckungen war die Uranmineralisierung im Bohrloch UR24-06, das 0,22% U3O8 über 0,7 Meter ergab und damit die stärkste und breiteste Schnittstelle des Projekts bisher markierte. Die Mineralisierung wurde zwischen 1087,8 und 1116,8 Metern gefunden, wobei die stärkste Konzentration zwischen 1088,6 und 1089,3 Metern in schwach grafitischem und pyritischem pelitischem Gneis auftrat.
Die Nutzung von Ambient Noise Tomography (ANT) durch das Unternehmen zur Priorisierung von leitfähigen Strukturen hat sich als erfolgreich erwiesen und bedeutende Ergebnisse im ersten ANT-Zielbohrloch erzielt. Mit nur 21 abgeschlossenen Bohrlöchern innerhalb des 65 Kilometer langen Projekts bleibt Ursa weitgehend unerforscht und birgt das Potenzial für mehrere Tier-1-Vorkommen.

Vancouver, British Columbia--(Newsfile Corp. - December 19, 2024) - Cosa Resources Corp. (TSXV: COSA) (OTCQB: COSAF) (FSE: SSKU) ("Cosa" or the "Company") is pleased to report assay results from basement-hosted radioactivity intersected in the fall drilling program at the Company's
Highlights
Uranium confirmed as source of anomalous radioactivity intersected by UR24-06, including
0.22% U3O8 over 0.7 metresUranium mineralization in UR24-06 is the strongest and widest intersected to date on the Project
Cosa's 2024 exploration confirmed prospective geology is present at Ursa and developed numerous follow-up targets which remain untested
Andy Carmichael, Vice President Exploration, commented: "In only 18 months, Cosa has significantly derisked the Ursa Project and proven that the geology of the Kodiak trend is highly consistent with that underpinning producing mines in the eastern Athabasca. Our strategy of using large-scale Ambient Noise Tomography (ANT) surveys to prioritize conductive strike produced the strongest and widest mineralization on the Project from our very first drill hole to test an ANT target. With only 21 drill holes completed within the 65-kilometre-long Project, Ursa has vast underexplored and increasingly prospective exploration space to fit multiple tier-1 deposits, and we have demonstrated that modern geophysical surveys have produced target areas far beyond conventional EM alone."
UR24-06 Assay Results
Chemical assays have confirmed that uranium mineralization is the source of radioactivity intersected by UR24-06 (See Cosa news release dated October 30, 2024). As at basement-hosted uranium deposits in the region (e.g, Gryphon, Arrow, and Eagle Point), mineralization is monometallic and significant enrichment of uranium pathfinder elements such as arsenic, nickel, and cobalt is not present.
The mineralization was intersected by drill hole UR24-06 (Table 1) which tested an ANT anomaly along the Kodiak conductive trend interpreted to reflect favourable structural disruption and/or hydrothermal alteration of the Athabasca sandstone. UR24-06 intersected a zone of sandstone-hosted structure and alteration from 814 to 923 metres. The unconformity was intersected at 1033.0 metres. Multiple intervals of basement-hosted uranium mineralization were intersected between 1087.8 and 1116.8 metres. The strongest mineralization is between 1088.6 and 1089.3 metres where disseminated and fracture-filling uranium mineralization within weakly graphitic and pyritic pelitic gneiss averaged
The results from UR24-06 significantly upgrade the Kodiak trend and validate Cosa's approach of using ANT surveying to prioritize conductive strike for drill testing.

Technical Disclosure
Drilling reported in this news release was completed with oriented NQ diameter drill core which was logged and sampled to capture geological information including alteration, structure, and mineralization. All drill core was systematically scanned for total gamma radioactivity using an RS-125 hand-held spectrometer and the average cps recorded for each 3-metre drill run. Intervals measuring over 1.5 times background levels were broken out and recorded. For intervals with elevated (>300 cps) radioactivity (RS-125), total gamma radioactivity was measured by removing sequential 0.1 metre lengths of drill core to an area with background radioactivity and scanned with an RS-125. For intervals measuring >500 cps (RS-125), spectral analyses were made using an RS-125 to characterize the relative contributions of uranium, thorium, and potassium to total gamma radioactivity.
Following completion of each drill hole, down-hole total gamma logging was completed using a Reflex EZ-Gamma system lowered inside the drill rods using the drill wireline. Measurements of total gamma were collected every 0.1 metres in both the down and up directions. Down-hole gamma logs were plotted alongside RS-125 total gamma measurements to confirm depths, handheld spectrometer readings, and assess total gamma radioactivity through intervals of unrecovered core.
Sampling was completed through zones measuring >300 cps using half-core samples between 0.1 and 0.5 metres in length. Samples were transported by Company personnel to SRC Geoanalytical Laboratories (SRC) in Saskatoon, Saskatchewan (ISO/IEC 17025:2005 accredited) for U3O8 assay and multielement analysis. Certified reference material CRM blanks were inserted into the split core sample series. SRC independently conducts a QA/QC programme comprising repeat analyses and insertion of CRM standards CAR218, BL4A, and BL2A. SRC's CRM results are verified by Cosa staff.
