Thor Mining Plc (AIM, ASX: THR) Bonya Tungsten & Copper Prospects Initial Findings



The Board of Thor Mining Plc (“Thor”) (AIM, ASX: THR) is pleased to announce positive findings from an initial surface sampling exploration programme.

The Company has now received encouraging assay results from preliminary rock chip samples taken from four of the 13 outcropping tungsten deposits that comprise the Bonya project approximately 30 km east of Thor’s Molyhil mine project in Australia’s Northern Territory.

Rock Chip samples were collected from the Tashkent, Jericho, Samarkand and White Violet prospects during preliminary reconnaissance prior to re-establishing access to the remaining deposits.


·     3.5% WO3 in rock chips and 1.6% in float from Samarkand deposit

·     1.37% and 0.6% WO3 in rock chips from Tashkent deposit

·     0.56% WO3 and 3.3% Cu in rock chips from White Violet deposit

·     0.81% WO3 and 1.06% Cu in rock chips from Jericho South deposit

·     Project area Exploration Target* of 3.0 – 4.9 million tonnes @ 0.3% – 0.5% WO₃

*Exploration Targets are conceptual in nature and there has been insufficient exploration to define a Mineral Resource under the JORC Code and it is uncertain if further exploration will result in the determination of a Mineral Resource.

As announced on 19 April 2018, on completion of the acquisition from Rox Resources Limited (ASX: RXL) and execution of the proper assumption documentation, subject to normal Northern Territory stamping anministerial approval processes, Thor and Arafura Resources Limited (ASX:ARU) will be in Joint Venture in respect of this tenement with Thor holding a 40% interest.


Mick Billing, Executive Chairman, Thor Mining (AIM, ASX: THR) talks about the recent Tungsten prospect purchase and provides an update on the Lithium investment in the USA (recorded 23rd April 2018)

Mick Billing, Executive Chairman, commented:

“These preliminary results support the validity of historical drilling and trenching assay data and bode well for the imminent development of the Bonya deposits.”

“In addition to robust levels of tungsten, it is encouraging that the assay results showed low levels of potential penalty elements and overall coarse grain mineralisation.”

“The potential for high grade copper mineralisation in some of the deposits is also very attractive with the proposed processing plant at Molyhil highly likely to be also suitable for copper flotation.”

“We are gearing up to fast track the assessment and development of the Bonya deposits within the 2018 field season. Provided some of these known prospects mature, alonwith others which we expect to find and develop, it is more than likely that Molyhiproduction life and throughput volume should increase substantially.”
