ROUYN-NORANDA, CANADA--(Marketwired - April 16, 2013) - Explor Resources Inc. (TSX VENTURE:EXS)(OTCQX:EXSFF)(FRANKFURT:E1H)(BERLIN:E1H) is pleased to announce the completion of its NI 43-101 Updated Mineral Resource Estimate for the Timmins Porcupine West Gold Property located in Bristol and Ogden Townships 15 kilometers from downtown Timmins, Ontario. The property is located in the famous Timmins-Porcupine mining camp within proximity to past and existing producers.

Open Pit Mineral Resources at a 0.25 g/t Au cut-off grade are as follows:
Indicated: 74,000 oz (1,248,000 tonnes at 1.85 g/t Au)
Inferred: 186,000 oz (2,502,000 tonnes at 2.31 g/t Au)
Underground Mineral Resources at a 1.70 g/t Au cut-off grade are as follows:
Indicated: 224,000 oz (1,758,000 tonnes at 3.96 g/t Au)
Inferred: 594,000 oz (6,145,000 tonnes at 3.01 g/t Au)

Chris Dupont, President and Chief Executive Officer of Explor Resources Inc commented: "We are very encouraged by this Updated Mineral Resource Estimate using drill data up to December 2012. Diamond Drilling has continued to intersect significant mineralization. The continuity from hole to hole as well as the grade encountered to date is very significant in terms of establishing both an open pit and underground gold resource."

It should be noted that the drilling to December 2012 has yielded an increase of 40% in indicated ounces and 119% increase in indicated tonnes over the June 2012 resource. Additional near surface planned drilling is expected to further increase the potential open pit-able resource.

The following tables summarize the sensitivity to the Mineral Resource Estimate in the Indicated and Inferred resource categories at various cut-off grades. For the purpose of this press release, Explor is reporting the open pit resource at a 0.25 g/t Au cut-off grade and the underground resource at a 1.70 g/t Au cut-off grade, as follows:

(1) Mineral resources which are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues, although the Company is not aware of any such issues.
(2) The quantity and grade of reported Inferred resources in this estimation are uncertain in nature and there has been insufficient exploration to define these Inferred resources as an Indicated or Measured mineral resource and it is uncertain if further exploration will result in upgrading them to an Indicated or Measured mineral resource category.
(3) The mineral resources in this press release were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the CIM Standing Committee on Reserve Definitions and adopted by CIM Council.
(4) Grade capping from none to 20 g/t was utilized on raw assays for the mineralized domains. Inverse distance cubed (1/d3) was utilized for grade interpolation and was based on 1m composites within a 5m long x 2.5m wide x 5m high block model.
(5) A bulk density of 2.89 t/m3 was used for all tonnage calculations based on samples taken by the authors of this resource estimate.
(6) An approximate two year trailing average gold price of US$1,650/oz and an exchange rate of US$1.00S=C$1.00 was utilized in the Au cut-off grade calculations of 0.25 g/t Au for open pit Mineral Resources and 1.70 g/t for underground Mineral Resources. Underground mining costs were assumed at C$70/t, with process costs of C$10/t and G&A of C$5/t. Open pit mining costs were $2.00/tonne for mineralized material and waste rock while overburden mining costs were $1.50/tonne. Process recovery was assumed at 95%.

It is important to note that the strike length of the gold mineralization is greater than 2000 meters. The continuity of mineralization continues to be confirmed, and the structure remains open on strike and at depth. Explor has intersected gold mineralization in 100 out of 105 holes drilled to date and 64 out of 65 wedges. Explor has concentrated its efforts on the south limb of the syncline and very little work has been completed on the north limb of the syncline.

The mineralization on the south limb 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. The larger zones of mineralization display a strong spatial relationship with proximity to syenite intrusive rocks and high Fe-tholeitic volcanic rocks.

The Timmins Porcupine West Gold Property consists of 185 unpatented mining units and three 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. The 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 is open below 350 meters of vertical depth. Explor continues to drill 24/7 to explore and expand the known resource base.
