Okapi Resources Limited (ASX: OKR) (Okapi or the Company) is pleased to announce that its wholly owned subsidiary Okapi Resources Canada Ltd. has received from the Ministry of Environment, Government of Saskatchewan (GoS), a Crown Resource Land Work Authorization, an Aquatic Habitat Protection Permit, a Temporary Work Camp Permit, and Forest Product Permit; together these permits will allow Okapi to drill up to 10,000m in 24 drill holes as well as conduct ground based geophysical surveys of up to 100 line kilometers. The permit is valid through to October 2023.
Key Points
- Okapi Resources receives permits to drill at its Middle Lake Uranium Project
- Extensive historically data at Middle Lake, including high grade surface samples, drilling data and geophysics indicate strong potential for economic mineralisation
- Diamond core drilling program is being planned in the North America winter (Q1 2023)
- Permits allows for up to 10,000m of drilling in 24 drill holes
Okapi’s Managing Director, Mr Andrew Ferrier said:
“This is an important milestone for Okapi, as the Company continues to progress and advance its uranium projects in North America. Obtaining a permit to drill at our 80% owned Middle Lake Project in the Athabasca Basin, the world’s premier uranium district, provides the opportunity for the company to start exploration work on our highly prospective exploration properties located only 4km from the past producing Cluff Lake Mine which produced approximately 64 million pounds of uranium.
The proposed exploration program will focus on prioritising drill targets by reinterpreting the historic geochemistry, geophysics and drill data, combined with satellite imaging (currently underway) which will provide a structural framework. The highest priority drill targets will then be followed by a potential diamond core drilling program, that is likely to be conducted in the North America winter of Q1 2023.
Proposed Exploration Program
The Middle Lake Uranium Project has had a long history of exploration work completed with the last drill program occurring in the winter of 2015 comprising 17 shallow drill holes for a total of 1,851 meters of drilling. The drilling revealed areas of anomalous radioactivity and uranium concentrations associated with graphitic schist and mylonite; the exploration is consistent of that for unconformity style uranium deposits in areas adjacent to the contact between the underlying Archean Basement and Athabasca Group rocks.
Okapi’s immediate aim is to take the historic data and reinterpret and remodel the historic surface and drill data, geochemistry and geophysics to provide targets for drill testing. This will be combined with new remote sensing image interpretation currently underway that, when integrated with the historic, existing geophysical survey results, will provide a structural framework that can be incorporated into the geologic modelling. The application of multi-spectral satellite imaging to exploration at Middle Lake, and the enhanced software capacity now available, can readily detect areas of alteration associated with Uranium mineralisation.
The targets generated from the geologic model will then be followed by a potential diamond core drilling program that is likely to be conducted in the North America winter of Q1 2023. The drill permits will allow Okapi to drill up to 10,000m in 24 drill holes.

Boss Set to Ship First U308 from Honeymoon
Highlights
- Startup production exceeding ramp-up schedule per the feasibility study (FS) estimates
- NIMCIX columns 2 and 3 on target for commissioning in Q3 and Q4, respectively in 2024
- Commissioning continues to advance, with key metrics remaining ahead of FS estimates:
- oWellfields continue to average 80 - 100mg/L vs FS estimate of 47mg/L (~100% uplift)
- oIon Exchange loaded resin recoverability remains at 100%
- oResin loading normalising at FS estimate of 27 g/L
- oElution performance exceeding FS estimate at 7 – 9 g/L
- First uranium sale to occur with revenue being received this quarter
- Boss remains highly leveraged to rising uranium price
Boss will now make its first delivery to European nuclear utilities under its existing sales contracts, with revenue to be received in the current quarter.
With NIMCIX Column 1 performing to expectations and construction of Columns 2 and 3 on track for completion in the September and December quarters, 2024 respectively, Boss expects production to total at least ~850,000lbs of U308 by June 30, 2025, in line with its Feasibility Study schedule1.
Boss Managing Director Duncan Craib said:“The start-up phase at Honeymoon is proceeding comfortably to plan, with all the key metrics running in line with, or exceeding, the forecasts contained in the Feasibility Study schedule.
“Construction of the second and third columns is also advancing well, ensuring we are on track to continue increasing our production rates. Total production in FY26 is set to meet or exceed our feasibility study forecasts at 1.63Mlb. The addition of columns 4, 5 and 6 are forecast to further increase the production rate to nameplate capacity of 2.45Mlb/annum by year three.”

Production update
Operational focus over the coming months remains on optimisation of the ion exchange, elution, precipitation and drying and packing processes.
Wellfield performance continues to impress, with tenors from individual wellfields into the PLS averaging 80 - 100 mg/L. Honeymoon’s feasibility study assumed PLS grade of 47 mg/L based on results from the project’s previous operation. Boss is managing the grade of uranium being leached to maximise wellfield recoveries.
Consumption of reagents in the wellfields of sulphuric acid and ferric (pH and Eh) are normalising as per FS expectations. The lixiviant chemistry, as proved during the field leach trial, continues to demonstrate superior performance at commercial throughput rates. The increased leach efficiency leads to a more efficient loading on the ion exchange resin, effectively lowering operating costs as less reagents and power are required per drum of uranium.
Stripping of uranium from the loaded resin continues to be virtually 100%, also demonstrating that the ion exchange process is working as designed, resulting in a high-grade concentrated eluate greater than 7-9 g/L.

Lo Herma ISR Uranium Project, Resource Drilling Funded
HIGHLIGHTS
- Upcoming Q3 resource drilling is fully funded
- Drilling will target expansion and upgrade of the current Inferred Mineral Resource Estimate of 5.71 Mlbs U3O8 at average 630ppm
- Drilling to commence in the coming weeks - starting late July or early August
- Planned rights entitlement offer to all shareholders on the same terms as the recent placement - details to be provided in due course
As previously advised on 2nd of May 2024, the planned 2024 drilling permit at Lo Herma allows for up to 76 drill hole locations including construction of up to 5 groundwater monitoring wells. This next phase of drilling will focus on expanding the resource areas and where possible, upgrading the current mineral resource classification (Table 1). Collection of important data including, hydrogeologic parameters of the mineralised aquifers and collection of rock core samples for metallurgical testing will be also prioritised. GTI intends to mobilise drilling rigs to Lo Herma as soon as the activity is fully permitted which is anticipated to be during late July or early August 2024.
Following completion of the 2024 drill program at Lo Herma, GTI intends to publish an updated mineral resource estimate and exploration target range for the project. The Company expects that the updated mineral resource estimate will support near-term development of a Scoping Study to demonstrate the economic potential of the project.
GTI Executive Director Bruce Lane commented, “We are pleased and excited to have received investor support and funding to continue moving forward with our planned resource expansion drilling at Lo Herma. Matt and the team in Wyoming have put us in a great position to complete the drilling program this quarter, with a revised mineral resource estimate to be rapidly advanced post-drilling. This work prepares GTI for a potential Lo Herma scoping study which we hope to commence later this year on the basis that we can significantly grow the uranium resource estimate to a similar scale to ISR uranium mines currently being constructed or planned in Wyoming at Ur-Energy’s Shirley Basin project & Encore’s Energy’s Gas Hills project.”
FIGURE 1. GTI WYOMING PROJECT LOCATIONS
LO HERMA GEOLOGIC SUMMARY
The Lo Herma project is located on the southern end of the west flank of the Powder River Basin (PRB), a regional asymmetric synclinal basin hosting a sedimentary rock sequence of about 15,000 feet in the deeper portions of the basin. The basin is bounded by the Bighorn Mountains on the west, the Black Hills to the east, and the Casper Arch, Laramie Mountains, and Hartville Uplift along the southern margin. Along the edges of the basin, progressively older sedimentary units outcrop at the surface as you move away from the synclinal axis of the basin.
The target host geology for Lo Herma project is located in and around the contact of the Eocene Wasatch Formation (Wasatch) and the Paleocene Fort Union Formation (Fort Union).
