Initial RAB Drilling Programme Results on Thor's Makosa Prospect, Senegal Confirm Bedrock Mineralisation Over 2.2km Strike Length

VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 2, 2012) -

NOT FOR DISSEMINATION IN THE UNITED STATES OR FOR DISTRIBUTION TO U.S. WIRE SERVICES

Thor Explorations Ltd. (TSX VENTURE:THX) ("Thor") is pleased to announce that bedrock mineralisation has been confirmed over a strike length of 2.2km on the Makosa Prospect in the Douta Project. Results for the first approximately 2,801 metres of the 7,900m rotary air blast ("RAB") drilling campaign completed in late March 2012; have now been received. The key findings from this work include;

  • Gold mineralisation is observed on each of the 6 drillhole fences tested
  • Multiple mineralisation zones noted on the widest fence tested
  • Near surface mineralisation observed (oxide zone)
  • Bedrock mineralisation open to both the north and the south along strike

In addition to the confirmation of this bedrock mineralisation, as indicated by the presence of anomalous gold values (>0.5 g/t Au), highlights from the programme, include the following;

A full table of all holes with intercepts over 0.5 g/t Au is available on the Thor website at http://www.thorexpl.com/s/DoutaDrillingProgramme.asp.

Thor intends to test these mineralised zones at depth through diamond drilling or RC drilling. This will enable the determination of grades and intervals with greater confidence than can be achieved through RAB drilling and will provide assay results which can be used to support resource estimation. The RAB results reported here will be used to define the location and extent of mineralised zones.

Segun Lawson, CEO of Thor Explorations commented:

"We are very pleased with the initial results from the RAB drilling programme. These results confirm our initial interpretation of the mineralised system over the Makosa Prospect and continues to support managements view of the significant potential of the Douta project.

We expect to receive the outstanding RAB results over the next month. Our exploration programme is on-going and has been designed to increase our level of understanding of the controls and extent of the gold mineralisation."

RAB Drilling programme details

The RAB programme was completed in late March and consisted of 184 holes for a total drilled length of 7,880m. These RAB holes targeted a number of features including the extension of identified mineralisation from the 2011 trenching campaign, the extension along strike of artisanal workings, and geological and geophysical targets. The results reported correspond to the first 56 holes representing 2,800m across the first 6 drillhole fences completed across the mineralised trend, covering a strike length of 2.2km. Of the total 14 drillhole fences; outstanding results account for 2 drillhole fences to the south - bringing the total tested strike length to 2.6km - and an additional 6 drillhole fences which infill the presently tested strike length to 200 metres spacing. These outstanding drillholes cover 5,099m of drilled length, or approximately 65% of the total programme.

The RAB fences were spaced at approximately 200m intervals and oriented on an approximate bearing of 123 degrees, perpendicular to strike. The programme was focussed on understanding mineralisation within the oxide zone, with holes ending in the fresh or transitional units.

The maps (please see reference: http://www.thorexpl.com/i/maps/Douta_map1.jpg and http://www.thorexpl.com/i/maps/Douta_map2.jpg) describe the highlights of the RAB drilling programme noted in Table 1 above, and demonstrate the continuation of mineralisation across the body.

Sample preparation and analysis

Samples are composed of 2.0 - 2.5kg of material typically composited from 2 or 3 metre drilling intervals, sampled using the spear method. Samples were dispatched to the ALS laboratory in Bamako, Mali in batches of 500 samples. Samples were prepared in the lab by fine crushing to approximately 85% passing 2mm, after which a split of 250 grams was pulverised to 85% passing 75 microns. A charge of 50g was then used for fire assay analysis with an Atomic Absorption Spectrometry (AAS) finish. Results are reported with a lower detection limit of 0.01 g/t Au.

Quality Assurance/Quality control (QAQC) procedures

Quality control samples consisting of two Certified Reference Materials (CRMs), coarse blanks and sample duplicates were used to monitor sampling and analytical quality, for an overall insertion rate of approximately 17% control samples. Sample Duplicates were taken by spear sampling twice the target weight of the typical sample, and then riffle splitting this material to form both the 'Normal' and 'Sample Duplicate'. Sample Duplicates were inserted randomly at a rate of approximately 1 in 15. Two CRMs, one high grade and one low grade, were added to the batches at a combined rate of 1 in 20, also inserted randomly. Coarse Blanks consisting of material obtained from outcrops of a local barren granite were inserted at a rate of approximately 1 in 25.

The QAQC results for the reported batches are considered acceptable. Sample Duplicates report acceptable repeatability when compared with their corresponding Normal Sample. The majority of CRMs report within the accepted upper and lower thresholds, with overall biases of less than ±5% relative. Only a single blank reported gold values greater than the detection limit. These results provide assurance that the results obtained provided a reliable basis for delineating the mineralised trends and planning further follow-up drilling.

Qualified Person

The technical information contained in this press release has been reviewed by Dr. Edmund Sides, PGeo and EurGeol, who is a qualified person for the purpose of National Instrument 43-101 and an employee of AMEC who have been engaged by Thor Explorations Ltd. to provide advice on evaluation data collection and resource estimation. Edmund Sides visited the Douta project from 25th to 27th January 2012 prior to the commencement of the RAB drilling programme. During his site visit he inspected some of the 2011 trenches and artisanal workings on the Makosa target and provided advice on the sampling and QA/QC procedures being used by Thor.

Thor Explorations Ltd. is a Canadian mineral exploration company engaged in the acquisition, exploration and development of mineral properties located in Senegal and Burkina Faso. Thor holds a 70% interest in the Douta Gold Project located in southeastern Senegal. The Douta Gold Project lies within the Kéniéba Inlier which hosts in excess of 40Moz of gold and has attracted major international mining companies.

Please note that the data included in this press release is conceptual in nature and that there is insufficient exploration data available to define a mineral resource. Further exploration is planned. It is too early to say if the program will result in the target being able to be defined as a mineral resource.
