Explor Intersects 28.46 g/Tonne Au Over 3.30 Meters on Timmins Porcupine West

ROUYN-NORANDA, CANADA -- (Marketwire) -- 05/15/12 -- Explor Resources Inc. (TSX VENTURE: EXS)(PINKSHEETS: EXSFF)(FRANKFURT: E1H)(BERLIN: E1H) is pleased to announce the results of 7 drill holes being the next series of holes on the diamond drilling program. Hole #11-61W1, 11-61W2, 11-62W4, 12-65, 12-66, 12-69, and 12-70, are reported in this press release.

Chris Dupont, President and Chief Executive Officer of Explor Resources Inc. commented: "We continue to be extremely pleased and encouraged by these excellent drill results. The continuity of the mineralization from hole to hole as well as the grade encountered to date with the increasing width as we go to depth are very significant in terms of establishing a potentially large mineable gold resource."

The "A" Zone identified through modelling strikes east northeast and dips to the north at 70 to 80 degrees. The drilling confirms the association of gold mineralization with Quartz feldspar (QFP) and syenite porphyry, found at both the Lakeshore and West Timmins Properties. Five mineralized zones designated "A" thru "E" have been identified. The larger zones of mineralization display a strong spatial relationship with proximity to syenite intrusive rocks and high Fe-tholeitic volcanic rocks. The 3D Geological Model may be viewed on our website: www.explorresources.com.

It is important to note that the strike length of the gold mineralization is greater than 2000 meters. The structure is still open on strike and at depth. The first phase of drilling was concentrated on mineralized Zone "A" located on the south limb of the geo-syncline. The program will continue to test the discovery zone along strike and at depth. The Company is encouraged by that the fact that on the "A" Zone, 89 out of 90 holes and all the wedges drilled from the main holes have intersected gold mineralization and that the grades encountered would in theory, support a profitable future underground mining operation at current gold prices.

The wedges holes reported in this press release were designed to test the continuity of the mineralization as we proceed out from the discovery Hole #10-30 (previously reported in press release dated November 23, 2010) and were designed to determine the depth continuity of the high grade mineralization encountered in Hole #10-30. The holes 12-65, 12-66, 12-69 and 12-70 were designed to test and expand the high grade resources near surface and at the eastern end of the 2 km known mineralization. The continuity of mineralization continues to be confirmed, and the structure remains open on strike and at depth.

Explor is focused on developing a mineable resource based on the drill results that have been obtained to date. The NI 43-101 technical report has been completed by MRB Associates of Val-d'Or, Quebec and P & E Mining Consultants of Brampton, Ontario (Press Release dated December 05, 2011).

Explor continues to drill 24/7 on the Timmins Porcupine West Property. Assays are pending on 8 drill holes.

The NI 43-101 technical report is available on SEDAR and on the Company Website. The results of Explor's drilling have been incorporated into the Timmins Porcupine West Exploration Video which is available for viewing on the website. The Timmins Porcupine West Project has as a Target Model "The Hollinger-McIntyre-Coniaurum System." To date, Explor's drill program has confirmed the idealised Hollinger-McIntyre-Coniaurum (HMC) isometric model. The HMC system has produced a total of over 30 million oz of gold and is spatially associated with the Pearl Lake Porphyry.

The Timmins Porcupine West Gold Property consists of 185 unpatented mining units and 3 patented claims located in the Bristol and Ogden Townships in the Timmins-Porcupine Mining Camp for a total 3,200 hectares. The property is contiguous with Lakeshore Gold West Timmins Mine. Highway 101 bisects the property and provides access from the city of Timmins located 13 km to the east.

The property has been explored since 1927 by numerous ground geophysical surveys and diamond drilling of up to 111 holes. In 1984, Dome Exploration discovered and delineated a gold mineralized zone that was approximately 350 meters long and 45 meters wide and was open below 350 meters of vertical depth. The drill program on the Timmins Porcupine West Property is ongoing.
