Interim results from XRF guns for three of the four targets feature 29 metres at 0.75% tungsten oxide from 81 metres.
Other preliminary results include 27 metres at 0.32% tungsten oxide from 71 metres and 16 metres at 0.43% copper in the same hole.
Thor’s executive chairman Mick Billing said: “These are very exciting interim results, particularly from the White Violet deposit, where results are substantially better than expectations.
“The inclusion of attractive copper interim assays from several holes also elevates the potential of the Bonya area in general, but White Violet especially.
“We look forward to the interim results from the Samarkand drilling, and also to the full laboratory assays expected during May.”
Exploration included drilling and trenching
The 2,184-metre reverse circulation (RC) drill program targeted the Samarkand, Jericho, White Violet, and Tashkent deposits.
In addition, 200 metres of trench sampling across each of the Marrakesh and Tashkent deposits was complete.
Arafura owns 60% of the Bonya project alongside Thor’s 40% operating interest.
