Usha Resources Completes First Scoping Drill Hole at the Jackpot Lake Lithium Brine Project; Supports Clayton Valley Style Model and Lithium-Bearing Brine Potential
Usha Resources Ltd. (TSXV: USHA; OTCQB: USHAF) announced successful drilling at its Jackpot Lake Lithium Brine Property, confirming lithium presence in shallow soils and a higher-porosity sand-conglomerate zone. The hole JP22-1 was drilled to a depth of 1,723 feet, with lithium grades up to 300 ppm in surface soils, supported by historical data reflecting an average of 175 ppm. The project is located in Clark County, NV, and spans approximately 2,800 acres. Additionally, evaporitic crystallization was confirmed at depths of up to 1,629 feet, indicating favorable conditions for lithium brine formation. The company is advancing its second drill hole following this encouraging initial outcome.
- Confirmation of lithium grades up to 300 ppm in shallow soils.
- Successful completion of the first drill hole, JP22-1, to a depth of 1,723 feet.
- The project shows geological similarities to Clayton Valley, home to North America's only lithium mine.
- Identified higher-porosity sand-conglomerate zone likely to be pumpable for lithium extraction.
- The basin area estimated at 10,900 acres, open for potential expansion.
- Mechanical and stabilization issues encountered during drilling, terminating the hole at 1,723 feet.
Company Confirms Presence of Lithium in Shallow Soils, Higher-Porosity Sand-Conglomerate Zone at Basin Bottom; Evaporitic Salt Crystallization Confirmed to Extend to Depth of 1,629 feet with Zones of up to
VANCOUVER, BC, Feb. 7, 2023 /PRNewswire/ - Usha Resources Ltd. ("USHA" or the "Company") (TSXV: USHA) (OTCQB: USHAF) (FSE: JO0), a North American mineral acquisition and exploration company focused on the development of drill-ready lithium and other battery and precious metal projects, is pleased to announce that it has successfully completed hole JP22-1 at the Jackpot Lake Lithium Brine Property ("Project"). The Company will now proceed with drilling its second hole and sampling JP22–1.
USHA's 2023 drill program marks the first drill testing of the Jackpot Lake Project which is hosted within a basin estimated to be 10,900 acres and 625 metres deep. JP22-1 was completed to a total depth of 1,723 feet or 525 metres below ground and now confirms:
- Support for a similar geologic setting to that of Clayton Valley, hosting Albemarle's Silver Peak Nevada Lithium Mine, the only producing lithium mine in North America.
- Lithium is present in JP22-1 at a grade of up to 300 ppm within ten samples collected from shallow surface soils (<442 ft). The Project target was identified based on historical geophysical studies and 129 core samples collected by the USGS with an average lithium value of 175 ppm.
- Evaporitic crystallization, indicative of a brine-forming environment, extends to the top of the basal conglomerate, with interbedding, veining and inclusions increasing significantly beginning at a depth of 1,250 feet (381 metres). Interbedded zones included up to
90% evaporites. - A higher porosity zone comprised of sand and conglomerate with evaporite crystallization was identified beginning at 1,629 feet that continued on to the bottom of the hole at 1,723 feet or 525 metres.
- Static water was present at approximately 146 feet. The total water column at the Project is anticipated to be greater than 1,577 feet or 481 metres.
Most notably, the hole terminated in a higher porosity zone of sand and conglomerate. Reaching this sand-conglomerate zone was a high priority for the program as it should contain the greatest porosity within the basin aquifer and serve as a pumpable zone into which the fluids above can drain (See Figure 1). As per the Preliminary Economic Assessment (PEA) completed by Pure Energy Minerals for their Clayton Valley project, their sand and conglomerate zone was identified to contain a large volume of brine with superior grades (See Figure 2).
"The significance of evidence supporting the geologic setting coupled with the geological similarities and notable proximity to the sole domestic producer of lithium in the United States bodes well for USHA's future potential – both near and long-term," said Deepak Varshney, CEO of Usha Resources. "We have been very pleased with our maiden drilling program findings to-date and it's great seeing the core beginning to come out of the ground. Shallow basins with the characteristics of Jackpot are uncommon and to be able to validate our thesis for the Project on the first drill hole is very exciting. We are eagerly now moving on to hole number two as sampling of JP22-1 gets underway. Brine projects have the ability to move towards production much quicker than their counterparts in the hard rock space, and the identification of heavily crystallized layers overlaying permeable pumpable sands and conglomerate, along with confirmed lithium in soil samples, shows that Jackpot has the potential to produce and help meet this demand in the coming decade."
Surface casing was set to a depth of 500 feet and perforated two-inch PVC casing was installed from 500 feet to 1,698 feet to allow formation fluids to flow through the casing. The hole was terminated at 1,723 due to mechanical and hole stabilization issues attributed to saline conditions, as the bentonite mud broke-down very quickly below approximately 213 meters (700 ft) and greater than usual quantities of bentonite were required.
The Company now will proceed with preparation for sampling. Fluids in the wellbore will be developed out of the hole via airlift to remove potential drilling contaminants. The well will be allowed to recover and equilibrate after the airlift development. Upon completion of well development activities, individual passive discrete samples will be collected using HydraSleeve™ and Snap Sampler™ technology. Sample zones will target stratigraphic features expected to contain brine and informed by geophysical logs of the wellbore taken prior to sampling. These samples will be sent to an independent lab and analyzed for lithium, boron and other minerals typical of lithium enriched brine systems.
USHA's Jackpot Lake Lithium Brine Property is located within Clark County, 35 kilometres northeast of Las Vegas, Nevada, and is comprised of 140 mineral claims that total 2,800 acres (approximately 11.3 km2).
The Project's geologic setting is similar to that of Albemarle's Silver Peak Nevada Lithium Mine, the only producing lithium mine in North America, which has operated continuously since 1966, where sediments from lithium–rich surrounding source rocks accumulate and fill the deposit leading to a potential concentration of lithium brine due to successive evaporation and concentration events. Considering the elevated lithium concentrations identified in historic soil samples, such events could theoretically concentrate lithium as rainwater passes through these materials, developing enriched brines at depths.
The Company has permitted 2,700 metres over six holes and has commenced a maiden drill program with the goal of defining a 43-101 resource. The Project target was identified based on geophysical studies and 129 core samples collected by the USGS with an average lithium value of 175 ppm with a high of 550 ppm. The present average grade for Albemarle's project is approximately 121 ppm.
Modelling indicates that the Project target comprises the entirety of the Company's claim block (2,800 acres; 11.3 km2) and is open in all directions for expansion. The target is shallow, predominantly above bedrock depths of 625 meters, and is approximately 450 metres thick. The total basin within which the target is situated is estimated to be approximately 10,900 acres.
The Project's Qualified Professional (QP) is Michael Rosko, a professional geologist with over 30 years of experience, with extensive experience with world-class lithium brine projects including Tier 1 projects such as Galaxy's Sal de Vida Deposit, Millennial Lithium's Pasto Grandes Deposit, and Lithium America Corp's Cauchari-Olaroz Deposit.
