MinRex Resources (ASX:MRR) reports it has launched a reverse circulation (RC) drilling program at the Sisters Lithium-Tin-Tantalum Project near Marble Bar in Western Australia.
MinRex reports that the first phase of drilling will incorporate 18 RC drillholes totalling about 2,500m.
The Sisters Project is situated 1.75km east of Global Lithium’s (ASX:GL1) Archer lithium deposit, which hosts 10.5Mt @ 1.0% Li2O.
The project hosts the same greenstone belt as the Archer Deposit. Reconnaissance concentrated on the identification of outcropping lithium rich pegmatites in areas between the greenstone belt and the Homeward Granite contact.
Commenting on the drill program, MinRex Resources Managing Director George Karageorge said: “We are excited to have commenced drilling over the Sisters Lithium Project proximal to the Archer Lithium Deposit.
Based on the first RC drillhole we have intersected 2 zones of pegmatites varying from 4m to 6m thick which indicates a series of stacked pegmatites. We aim to drill 10,000m over 4-6 phases of drilling programs over Sisters and Moolyella North in the next 2 quarters.“
At the Sisters Project, extensive pegmatites were delineated within granite-greenstone “goldilocks zone”
At the Sisters Project, extensive pegmatites were delineated within granite-greenstone “goldilocks zone”. These zones are typical of all major lithium deposits in the Pilbara region of Western Australia.
Two zones of spodumene rich pegmatites were located in the southern zone of E45/5871 striking in a north-south direction with the greenstone lithology.
This lithium rich zone is approximately 500m in length by 250m in width. These pegmatites are striking between 200 and 550 with individual pegmatites ranging from 50m to 300m in length.
Some of the pegmatites range from 0.5m to 3.5m in width with some lepidolite pegmatite dykes trending the same orientation as the main pegmatites.
On 2 August 2022, the company announced the high-grade rock chip sample results, which yielded 3.42% Li2O, 1.59% Li, 105 ppm Cs, 80 ppm Ta, 120 ppm Nb, 130 ppm Sn, 1,980ppm Rb from the stacked pegmatites.
Drilling has concentrated around the newly identified lithium-rich pegmatites.
MinRex is an Australian based ASX-listed emergent battery metals explorer with Lithium-Tin Tantalum Projects in the Pilbara (WA) in close proximity to ‘world-class’ lithium and tantalum producers.
The company also has a ‘highly prospective’ portfolio of gold-copper projects in the Murchison and Pilbara Regions (WA) and gold-silver-copper and other metals projects in the Lachlan Fold Belt (NSW).
The company’s tenements package cover 1,000km-square of ‘highly prospective’ ground targeting multi-commodities type deposits. It also currently has JORC 2012 resources totalling 352,213oz gold at its Sofala Project (NSW).
