Thor Mining has announced that the Company has confirmed extensive tungsten mineralisation from the first stage of exploration at the Samarkand deposit, one of thirteen known tungsten deposits within the Bonya project.

The Bonya tenement is a joint venture with Arafura Resources (60 per cent), adjacent to the Molyhil mine project in the Northern Territory of Australia. Thor Mining is the joint venture (JV) operator.
Samples collected via systematic sampling program, in December 2018, from trenches excavated across the deposit more than 40 years ago.
• Better intercepts include:
• Trench 1: 7 metres at 6,670ppm (0.667 per cent) WO3 and 3 metres at 3,073ppm (0.307 per cent) WO3
• Trench 2: 3 metres at 2,711ppm (0.271 per cent) WO3
• Trench 3; 3 metres at 2,039ppm (0.203 per cent) WO3
“Samarkand is just one of what we believe will be series of satellite tungsten and copper deposits within economic trucking distance of Molyhil, thus making the case for Molyhil development even more compelling,” says Mick Billing, Executive Chairman.
“We now have confirmed tangible evidence of extensive surface outcropping tungsten mineralisation at Bonya, including mineralisation extending in excess of 500 metres of strike at Samarkand.”
According to Thor, current indications show that Bonya tungsten mineralisation is coarse grained and may be amenable to low cost pre-concentration by x-ray ore sorting and treatment at the Molyhil processing plant.”
“Our discussions and negotiations with potential partners continue with regard to Molyhil project level offtake and investment,” Mr Billing continued.
Samarkand is one of several tungsten deposits within the Bonya Range and is located approximately 350 kilometres ENE of Alice Springs and approximately 30 kilometres east of Thor’s 100 per cent owned Molyhil deposit.
The geological setting of the Samarkand tungsten deposit comprises steeply north east dipping meta-sedimentary rocks of the Kings Legend Amphibolite formation with multiple local pegmatite intrusions. Tungsten mineralisation is typically coarse grained occurring as discrete scheelite crystals dispersed preferentially within select lithologies within the formation. The rocks are interpreted to have been hydrothermally altered during the mineralisation event, and then strongly regionally metamorphosed to amphibolite grade.
