Kali Metals Ltd has doubled the strike length of a tin target at the Sweetwater Prospect, part of the company’s portfolio of tin-lithium projects in the Southern Lachlan Fold Belt of southeast New South Wales and northeast Victoria.
The prospective strike at Sweetwater now stretches for more than 3.9 kilometres, with outcrops of up to 20 metres in width.
The strike expansion was highlighted by 14 new rock chip samples, which peaked at 16.7% tin, with additional tantalum grades of up to 380 parts per million (ppm) and niobium up to 580 ppm.
Exploration wins on two fronts
“Our exploration in the Eastern States is progressing incredibly well,” Kali Metals managing director Paul Adams said.
“Recent rock-chip results from our Sweetwater Prospect have returned extremely high-grade tin values.
“The tin-bearing rocks extend over a sizeable area and have now been mapped for over 3.9 kilometres in cumulative length and remain open along strike.
“The next step for Sweetwater is confirming the continuity of tin mineralisation between the occurrences and defining the average grades over a larger extent of favourable rocks, with the aim of designing a preliminary drill program.
“In addition, we have also opened a new exploration front at the Mt Cudgewa Tin Prospect.
“Our recent LiDAR survey at Mt Cudgewa has confirmed our previous prospectivity assessment, identifying numerous long-forgotten tin workings from the early-1900s and consequently, a soil sampling campaign has already begun.
“With wins on both exploration fronts, we are looking forward to announcing more news from our Southern Lachlan Fold Belt projects during 2025.”
Kali’s soil program will collect samples from 880 locations over the Mt Cudgewa area, divided into three zones around historical workings, potential extensions to mineralised structures and areas with potential to host distal tin-bearing structures.
The company expects to field the results from the soil program in May this year.
