- Inferred Mineral Resource of 1.66 Mlbs U₃O₈ for Great Divide Basin Prospects
- Initial Exploration Target range estimated at Great Divide Basin Prospects
The Thor, Teebo, Odin, Loki and Wicket prospects (GDB Prospects) are located within Wyoming’s Great Divide Basin (GDB) Uranium District in Sweetwater County, Wyoming (WY). The GDB prospects lie within a 15-mile (~24 km) radius of Ur-Energy Inc’s (URE) actively producing Lost Creek ISR uranium processing plant and the 18Mlb Lost Creek deposit. Other known deposits in the vicinity include URE’s Lost Soldier and Shirley Basin Deposits and Uranium Energy Corp’s (UEC) Twin Buttes, Antelope, and JAB Deposits.
Exploration at Great Divide Basin
GTI has conducted two exploratory drilling campaigns at Thor between November 2021 to March 2022 and September 2022 and October 2022. 170 drill holes for a combined ~82,000ft (~25,000m) of drilling were completed between the two drilling campaigns. Results of the two campaigns can be viewed at GTI’s ASX releases dated 29 March 2022 and 8 November 2022.
GTI began an exploratory drilling project in November 2022 to target mineralization at the Odin, Loki, Wicket, and Teebo prospects in the GDB in 2021. Thirty-three (33) drill holes were completed between the Odin, Teebo, & Loki prospects. Results of the drilling can be viewed at GTI’s ASX release dated 22 December 2022.
Inferred Mineral Resource
GTI Energy Ltd (GTI or Company) has declared an initial Inferred Mineral Resource Estimate (MRE) at the Thor and Teebo Uranium Prospects located within GTI’s Great Divide Basin (GDB) Project located in Wyoming’s GDB uranium district.
The Inferred Mineral Resource Estimate (MRE) assumes mining by In-Situ Recovery (ISR) methods and is reported at a cut-off grade of 200 ppm U₃O₈ and a minimum grade thickness (GT) of 0.2 per mineralized horizon as:
1.32 million tonnes of mineralisation at an average grade of 570 ppm U3O8 for 1.66 million pounds of U₃O₈ contained metal.
In addition, an initial Exploration Target has been defined for both the Great Divide Basin prospects (excl. MRE areas) and the Lo Herma Project in the Powder River Basin (Table 1).
An initial Exploration Target Range for the Great Divide Basin Project of between 6.6 to 8.1 million tonnes at a grade range of between 420 ppm to 530 ppm U₃O₈ containing an estimated 6.1 to 9.5 million pounds of U₃O₈.
Table 1: Summary Of Exploration Targets & Resources
The potential quantity and grade of the Exploration Target is conceptual in nature and there has been insufficient exploration to estimate a JORC-compliant Mineral Resource Estimate. It is uncertain if further exploration will result in the estimation of a Mineral Resource in the defined exploration target areas.
