QUARTERLY ACTIVITIES REPORT

PERIOD ENDING 31 MARCH 2012

Dated: 30 April 2012

The Directors of Thor Mining PLC ("Thor" or the "Company") (AIM, ASX: THR) the Australian gold, tungsten and molybdenum explorer and developer, today lodged the following March 2012 quarterly report with the Australian Securities Exchange (ASX) as required by the listing rules of ASX.

QUARTERLY REPORT JANUARY TO MARCH 2012

MOLYHIL TUNGSTEN-MOLYBDENUM PROJECT (NT) (100% THOR)

Molyhil Definitive Feasibility Study (DFS)

The consultants, who are currently preparing an enhanced ore reserve calculation and detailed mining schedule for Molyhil, advise that completion of those tasks is now expected late in May or early June 2012. On that basis, the issue the Molyhil feasibility study is not expected before June 2012.

Substantial progress has been made to date, including:

Based on these estimates, and subject to the outcomes of the detailed mining schedule the operating costs of the proposed Molyhil operation (including royalty payments) are approximately US$110/mtu (metric tonne unit = 10Kg of WO₃)) after deduction of bi-product credits from the sale of molybdenum compared with revenue of US$360/mtu after deduction of APT processing cost discount.

The selling price in Europe of Tungsten APT now sits at US$440/mtu, while the price of Molybdenum Roasted Concentrates has improved slightly to between US$14.00 and US$15.00/lb.

Based on the diamond and reverse circulation (RC) drill programs completed in 2011 a renewed estimate of resources at Molyhil was completed, with results summarised in tables 1 & 2. The resource estimate was reported in detail on January 30th.

Table 1. Summary of Molyhil Mineral Resource Estimate (reported on 30 January 2012)

Mineral Resource reported at 0.1% combined Mo + WO3 Cut-off and above 200mRL only.

Note: minor rounding errors may occur in compiled totals.

Table 2: Comparison of 2012 and 2009 Molyhil Resource Estimates

Note 1: 1 tonne of WO₃ = 100 mtu's. The revised resource estimate contains 1,310,000 mtu WO₃.

Note 2: 1 tonne of MoS₂= 1,320 lbs Mo. The revised resource estimate contains 13,728,000 lbs Mo.

Exploration program

While some opportunities remain for extensions at the margins of the deposit as now outlined, this update of the Molyhil resource is now finalised and further drilling of identified areas of potential resource growth will be deferred until the development of the mine and associated infrastructure. Resource growth is now being pursued through exploration of the granted licences; EL22349, EL28948 and EL28949.

Initial stages of this work undertaken during the quarter have comprised the compilation and consolidation existing reports and geophysical data resulting in the identification of thirteen exploration targets. Determination of the requirement for additional geophysical data is in progress while the evaluation of the identified targets has commenced.

2012 June Quarter activity schedule

Definitive Feasibility Study (DFS)

Results from the DFS are scheduled to be available during the quarter, along with an updated resource estimate and ore reserve and mining plan.

Finance and sales agreements

Initial discussions have been held with a number of parties who have expressed interest in securing off-take agreements for the supply of tungsten and molybdenum concentrates, and also in various alternatives for financing the project. These discussions are ongoing.

GOLD EXPLORATION

SPRING HILL PROJECT - NT (THOR acquiring earn-in rights to up to 80% equity)

During the annual wet season interruption to field activities at Spring Hill, results of the 2011 diamond drilling were reviewed in detail in preparation for the continuation of activities.

A program of metallurgical testwork was commissioned to assess the potential for profitable production via heap leach extraction. The results from this have yet to be received.

Compilation and review of existing geophysical data is nearing completion and will assist with targeting the upcoming drill program. Specifically, this program will be designed to evaluate potential additional resources based on:

A program of metallurgical testwork was commissioned to assess the potential for profitable production via heap leach extraction. The results from this have yet to be received.

DUNDAS PROJECT - WA (60% THOR)

Further field work undertaken during the quarter has effectively completed the reconnaissance calcrete geochemistry across the three tenements. Assays received to date have highlighted an extension to the previously drilled Asgard anomaly and identified the new Gimli anomaly, both in the southern extent of E63/872.

2012 June Quarter Exploration schedule

Heritage clearance and commencement of the proposed drill program is anticipated during the June quarter.

Upon receipt of final calcrete assays, permitting for additional drill testing will be commenced.

CORPORATE AND FINANCE

During the quarter the Company raised further additional funds through the issue of 57 million ordinary shares, in placements to sophisticated investors in the UK. This issue raised A$840,000 before costs associated with the issue.

In addition a further 13,620,117 UK warrants and CDI options were converted during the quarter raising approximately A$343,000. Of those warrants and options, 9,529,301 were converted at or close to 31 March 2012 resulting in A$236,000 of those proceeds being received after quarter end.

A general meeting of shareholders has been scheduled for 17th May 2012 to ratify recent share issues and to authorise further issues necessary to fund ongoing exploration and evaluation activities.

Subsequent to the end of the quarter, Mr David Thomas was appointed to the board of Thor Mining PLC.
