Atco Mining Begins Drilling at Atlantic Uranium Project in Athabasca Basin

(TheNewswire)

Vancouver, British Columbia – TheNewswire - February 27 th , 2024 — Atco Mining Inc. (the “Company” or “Atco”) (CSE:ATCM ) ; ( OTC:ATMGF ) ; ( Frankfurt:QP9) is pleased to announce that drilling activities have commenced at the newly announced, joint-ventured 3,061-hectare Atlantic Uranium Project (“ Atlantic ” or the “ Project ”). Atlantic is situated in the prolific eastern Athabasca Basin in northern Saskatchewan (Figure 1).

The Project is currently under option with Standard Uranium Ltd. (“ Standard Uranium ”), an arms-length company listed on the TSX Venture Exchange (TSXV: STND). Pursuant to the option, Atco can earn a 75% interest in the Project over three years.

Highlights:

  • Standard Uranium’s geological team arrived at site on February 26 th and drilling has started on the first hole of the inaugural Atlantic program.

  • One diamond drill hole is testing high-priority target area A on the Project (Figure 2), investigating a significant density anomaly coincident with modeled electromagnetic (“EM”) conductors, and interpreted faults.

  • Additional drill holes will follow up on highly anomalous uranium results and a major structure intersected in previous drill hole BL-16-32.

  • Approximately 2,000-3,000 metres planned across 4-6 drill holes, targeting high-grade unconformity-related uranium mineralization.

The Company considers uranium mineralization with concentrations greater than 1.0 wt% U 3 O 8 to be “high-grade”.

“We are extremely excited that we’re able to kick-start our drill program so quickly,” said Etienne Moshevich, CEO of Atco. The next four to six weeks are going to be an important time for our Company and I look forward to updating our investors with our progress over the coming quarters.”

2024 Winter Drill Program

Atco’s joint-venture partner, Standard Uranium, and its team arrived on site on February 26 th , 2024, and diamond drilling on the first hole is currently underway. The winter program is the first drill campaign undertaken by Standard Uranium on the Project following its successful identification of high-priority targets in 2022-2023.

The Project covers 6.5 km of an 18 km long, east-west trending conductive exploration trend which hosts numerous uranium occurrences. Standard Uranium completed a high-resolution ground gravity survey on the western claim block in 2022, revealing multiple subsurface density anomalies, potentially representing significant hydrothermal alteration zones in the sandstone rooted to basement conductors.

The drill program is designed to follow up on highly anomalous uranium results returned from drill hole BL-16-32, in addition to testing the newly outlined gravity lows defined by the 2022 ground survey. On the western Atlantic claim block, drilling by Denison Mines in 2016 (Hole BL-16-32) identified 342 ppm uranium over 0.5 metres at the base of the sandstone, just north of target area A (Figure 2). Winter drilling will be focused in target area A which is defined by a 1,400-metre x 850-metre density anomaly at the unconformity coinciding with stacked EM conductors and an interpreted regional fault. Figure 2 shows the 3D density anomaly target at the unconformity depth slice, with projected basement EM conductors and interpreted fault trends.
