Infinity Mining rock-chip sampling has extended the pegmatite strike length of its recently-renamed Woody prospect in Western Australia’s Pilbara region from 1.5km up to 5.7km, with peak results of 2.9 per cent lithium oxide.
The company collected 98 samples from the site formerly known as Tambourah South, with 12 assays showing results above 1 per cent lithium oxide from outcropping pegmatites and 30 displaying visible spodumene or lepidolite. Management believes the recent discoveries are defining a new lithium corridor in an area where it holds a commanding 850 square kilometres of tenements.
Infinity has defined large lithium-caesium-tantalum (LCT) pegmatite swarms within an area of 1.8km by 650m, covering about one third of the tenement and with the remaining area yet to be explored. It is now planning a reverse-circulation (RC) drilling campaign at Woody in a bid to further define the prospect, with additional exploration set to kick off to the east of the operation.
Woody forms part of the recently-renamed Infinity lithium project that was formerly known as Tambourah.
In addition to the recent success at its namesake project, the company has also identified two new LCT pegmatites, dubbed the Buzz and Lightyear prospects, at the Hillside project nearby to the east. The pegmatites were discovered during a helicopter survey of the region where total of seven samples, each identifying a separate pegmatite outcrop, were assayed and indicated LCT enrichment.
While no lithium minerals were identified, anomalous grades of 15.8 parts per million caesium, 0.2 per cent rubidium and 12.6ppm tantalum were encountered.
Management says the geology and setting of Hillside are considered highly-prospective due to the host greenstone belt sitting within 10km of the granite that also hosts the Infinity project on the western side, in addition to multiple tin and tantalum discoveries.
The Infinity project sits about 70km south-east of Pilbara Minerals’ massive Pilgangoora lithium venture and 95km south-west of Global Lithium Resources' Marble Bar lithium project. Geologically, it lies within greenstones of the Apex basalt adjacent to the Yule granite complex and covers the pegmatite-favouring “Goldilocks zone” out to about 3km from the granite-greenstone contact.
Infinity’s Pilbara operations also sit within shouting distance of the ASX’s prime mover during the past year in Wildcat Resources, which holds the Tabba Tabba lithium project to the north-west. Last month, Wildcat recorded a 73m hit at 1.1 per cent lithium oxide from 266m, in addition to 45m grading 1.1 per cent lithium oxide from its Leia pegmatite at the operation and has seen its share price jump from 2.5 cents at the start of the year to peak at more than $1 last month.
Infinity also appears to be adopting a Toy Story theme to its new deposit naming convention with the additions of the Woody, Buzz and Lightyear prospects at its Pilbara holdings. Perhaps the company is looking to adapt the well-known catch phrase from the Pixar franchise that screams “to infinity and beyond”.
