Commenting, Mr Mick Billing, Executive Chairman of Thor Mining, said:

"A period of delivery, albeit there is still much more to do to achieve our goals."

"The Molyhil DFS upgrade, now completed, leads us to refocus on the next critical agenda items for this, our flagship project."

"We have intensified our efforts towards off-take & financing activities and we hope, during the coming months to announce progress towards these objectives."

"Additionally, securing equity in the nearby Bonya tenements, provides potential to increase both the life and the scale of Molyhil, while also providing exposure to very exciting copper and vanadium opportunities."

"The Pilot Mountain scoping study results are also very positive, and we now advance with confidence towards Pre-Feasibility Study activities."

 "We will continue to provide investors with regular updates in respect of activities and progress."

 

TUNGSTEN PROJECTS

Tungsten and Molybdenum Price Trends

At the date of this report, the price of tungsten, per mtu of APT (Ammonium Para Tungstate) was US$277.00/mtu, while the molybdenum price has held its strengthened position at around US$12.15/lb.  While the tungsten APT price weakened during the quarter, the price for tungsten concentrates has firmed in recent weeks , with 65% concentrate currently priced at US$245.00/mtu ( compared with normal expectations for at least US$50/mtu discount to APT), suggesting a tightening of global concentrate supply.

Industry discussion suggests that stronger pricing levels for both commodities are likely to continue for some time, with some forecasters predicting APT tungsten prices in excess of US$400/mtu.  In addition, suggestions for molybdenum are for supply constraints for several years, and a number of potential molybdenum off-take partners have indicated a willingness to discuss fixed price purchasing agreements.

MOLYHIL TUNGSTEN PROJECT - NT (100% Thor)

During the quarter, Thor announced an updated Definitive Feasibility Study (DFS) for the wholly-owned Molyhil tungsten/molybdenum project, demonstrating low cost of production, a robust project NPV of A$101million, and an IRR of 59%.

A full background on the project is available on the Thor Mining website www.thormining.com/projects.

On 8 January 2018, Thor announced an upgraded Statement of Open Pit Ore Reserve, increasing the open pit mine life by 1 year to 7 years, with increases in metal content of 10% for tungsten and 19% for molybdenum.

Adjacent to Molyhil, the Bonya tenements, which Thor acquired an interest in during the quarter, host outcropping tungsten deposits, along with a copper deposit and a vanadium deposit, which are under evaluation.

The Ore Reserve study also identified approximately 1 additional year of material considered economic for recovery via mechanised underground mining methods.  The resource continues below current reserve depth however portion of this is in the inferred category and additional drilling is required to allow it to be converted to reserve status.

Mineralisation has been shown to extend a further 200 metres below the base of the current resource. The current resource was constrained to 210 metres below ground surface.

Bonya

During the quarter, Thor completed the acquisition of an interest in a licence area close to Molyhil containing 13 known outcropping tungsten deposits, one copper deposit, and also hosts a vanadium deposit.    An initial drilling program is an important next step in assessing the tungsten deposits which directors believe, should add to both the life and the scale of Molyhil. Regulatory and traditional owner heritage clearance work to this end is in process.

Separately, the Company has commissioned and independent geologist to conduct an assessment of both the copper and the vanadium deposits, and we await the results of that assessment.  The vanadium deposit is of particular interest, with vanadium prices currently quoted at US$116/kg in Ferro-vanadium..

 

PILOT MOUNTAIN TUNGSTEN PROJECT - NEVADA USA (100% Thor)

Thor's Pilot Mountain Project, acquired in 2014, is located approximately 200 kilometres south of the city of Reno and 20 kilometres east of the town of Mina, located on US Highway 95.

The Pilot Mountain Project is comprised of four tungsten deposits: Desert Scheelite, Gunmetal, Garnet and Good Hope.  All of these deposits are in close proximity (~three kilometres) to each other and have been subjected to small-scale mining activities at various times during the 20th century.

During the quarter, the Company completed a Scoping Study which identified the potential for an initial operation with a 12 year life.

A full background on the project is available on the Thor Mining website www.thormining.com/projects.

The directors believe Pilot Mountain's resource is substantial on a global scale, and has potential for significant growth, in particular from the discovery in the August 2017 drilling program of an additional parallel zone of scheelite mineralisation at the Desert Scheelite deposit (Figure 6.). 

The directors believe that the Desert Scheelite resource, which outcrops at surface at the western end for more than 400 metres, has potential to develop into a long term open pit mining operation which, when supplemented by higher grade mineralisation from the other deposits at Pilot Mountain, has the potential for a longer term profitable operation.

This significant tungsten resource is strategically located in the USA and tungsten has been confirmed by the US Department of the Interior as a critical mineral in 2018.

Metallurgical testwork, conducted in 2013, demonstrated the successful production of saleable concentrates from Pilot Mountain mineralisation.  Further testwork is required to advance this to pre-feasibility study standard, and this next stage of metallurgical testwork commenced during the quarter.

Environmental study parameters are being established with relevant agencies, and Infrastructure studies have also commenced.

 

KAPUNDA COPPER PROJECT - SA (Thor earning 45%)

On 1st August 2017 Thor announced an investment in a newly incorporated private Australian company, Environmental Copper Recovery SA Pty Ltd. ("ECR"), initially via convertible loan notes of up to A$1.8 million, which will be used to fund field test work and feasibility activities at Kapunda over the next 3 years.  In turn ECR has entered into an agreement to earn, in two stages, up to 75% of the rights over metals which may be recovered via in-situ recovery ("ISR") contained in the Kapunda deposit from Australian listed company, Terramin Australia Limited ("Terramin" ASX: "TZN").

Earlier in the year (12 February 2018) Thor announced an Inferred Resource Estimate containing 119,000 tonnes of contained copper considered amenable to Insitu Recovery techniques.  The grade of the resource, at 0.25%Cu, is considered typical for copper Insitu Recovery operations.

Other near-term activities at Kapunda include continued community liaison in respect of project activities, testwork on historical drill core to determine the optimum extraction agent (lixiviant) most suited to the Kapunda deposit and establishing appropriate parameters for future field trials.

A first stage extraction test on historical core using glycine, a food additive, has been undertaken and outcomes showing copper, and potentially other potentially valuable metals recovered, and recovery rates, are expected shortly. Testwork trialling other potential lixiviants is also proceeding.

During the quarter, on 30 July 2018, the Australian Government Ministry for Science, Jobs and Innovation announced an offer to ECR for research funding of A$2,851,303, over a 30 month period, for the Kapunda In-Situ Copper and Gold Recovery Trial.  This funding is expected to significantly advance the Kapunda project feasibility work, while minimising the ongoing funding requirement for Thor, other than for the A$1.8 million required to earn the equity in ECR.

 

SPRING HILL GOLD PROJECT - NT (ROYALTY ENTITLEMENT)

In February 2017 Thor completed the A$3.5 million sale of its Spring Hill Gold project¹. The sale transaction carries an ongoing residual royalty of:

·    A$6 per ounce of gold produced from the Spring Hill tenements where the gold produced is sold for up to A$1,500 per ounce; and

·    A$14 per ounce of gold produced from the Spring Hill tenements where the gold produced is sold for amounts over A$1,500 per ounce. 

 No royalties were received during the quarter.
