Labyrinth Resources has released the results of preliminary mapping and sampling at its Comet Vale gold project in Western Australia.

The company said that the reconnaissance program has renewed its interest in the historically overlooked multicommodity prospectivity of the Comet Vale project. Reconnaissance samples are undergoing analysis and results are expected in two to three weeks. 

Acquired radiometric data showed numerous unexplained anomalies at the site. Pegmatite samples collected were coincident with these anomalies, though the radiometrics could be indicating alteration, variation in intrusives (more specifically fractionation) and faults.

These findings initiated a gridded soil sampling program. The soils will be assayed for lithium (Li), caesium (Cs), tantalum (Ta) and other rare earth elements whereas historical programs have focused on gold and some indicator elements for base metals. The soil samples will help to explain the geophysical anomalies.

The reconnaissance work also confirms historic positions of copper (Cu) and nickel (Ni) laterite mineralisation and prospective geology. The work noted more detailed variation in ultramafic intrusions, possibly explaining some anomalism seen in geophysical data. 

Labyrinth said that finding evidence to explain geochemical and geophysical variance is key to narrowing down targets.

Labyrinth Resources CEO, Jennifer Neild, said that the company is fortunate to have such a richly prospective tenement package for multiple commodities at Comet Vale. 

“This does mean going back to basics, and soil sampling programs are a great way to vector in on prospective intrusions, structures and in the best case, mineralisation,” Ms Neild said. 

“With the recent joint venture activity proximal to Comet Vale focused on lithium, Labyrinth has been identified as highly prospective tenure both internally and externally.”
