Exploration Results Shining Tree Gold Project - Ontario

Vancouver, BC – January 31st, 2011

Pro Minerals Inc. (TSX.V – PRM) announces that the Company has completed its first phase of diamond drilling on its Shining Tree Gold Project situated southwest of Kirkland Lake, Ontario. The program was managed by InteGeos Inc. of Bedford, Nova Scotia under the auspices of Robert D. Stewart, P. Geo..

Assay results for the program have been received and reviewed. InteGeos Inc. has yet to file with Pro its report on the work carried out. Once received, Pro will then file for work assessment credits.

The Shining Tree Gold Project, covering an area of 71.89 hectares, is located at the heart of the prolific Shining Tree mining camp south west of Kirkland Lake, Ontario. The project is located about 1.2 km west of the historic Ronda Mine which, in 1939, produced 2,727 oz/Au from 24 582 tons of ore, from the Ribble Vein, representing an average of 3.45 g/T Au (0.111 oz/t). It is also located at about 2000 m south of the Herrick gold deposit owned by Platinex. Recently, Creso Exploration Inc. (CXT-TSX.V) announced an intersection of 82.5 m averaging 13.30 g/t Au from drilling of their Minto project located at 1 200 m north of Pro Minerals Shining Tree Beilby Lake Gold Project.

Typically, gold occurs in hydrothermal quartz-carbonate veins developed in brittle rocks adjacent to shear zones as well as exhalative massive sulphide horizons. Alteration adjacent veins may include silicification, carbonatization, and potassic alteration and/or finely disseminated pyrite. Brittle rocks such as massive and hard rhyolite and syenite are particularly well-suited for hosting quartz veining. In the Shining Tree region, three sets of deep crustal structures, oriented north-south, northeast-southwest and northwest-southeast provided pathways to the hydrothermal gold-bearing solutions. Numerous occurrences of visible gold in quartz veins have been discovered and developed in the last century. Those gold occurrences such as Matona, Caswell, Churchill, Corona, Pet and Rhyolite, occur along a cryptic east-northeast structure that extends to join the Larder Lake Break in Larder Lake area.

During the fall of 2010, eight (8) grab samples have been taken on silicified felsic volcanic outcrops and four (4) grab samples on silicified diorite. The samples were assayed by Accurassay Laboratories using the Fire Assay method finished by AAS and Metallic Sieve. The best gold values were obtained from quartz-carbonate veins with fine sulphides injected in rhyolite. The best gold value obtained was 12.77 g/t Au. Three samples returned gold values higher than 1 g/t Au. All samples related to diorite and quartz-carbonate veins returned traces to low gold values (< 1g/T Au). However, the metallic sieve method confirmed the presence of free gold in the quartz carbonate veins injected in both the rhyolite and the diorite.

A total of 1509 metres of drilling was completed in December 2010. Eight drill holes, representing the first drilling ever bored in the Beilby Lake area, were set-up to test the 300 m long Beilby Creek target.

Drill-holes PRM10-1 to PRM10-3 were bored in the southerly direction from the same drill site, with different dips (-45, -65 and -85 respectively) and different lengths (344.30 m, 173.74 m and 145.09 m respectively). Those holes returned traces to very low gold values.

Drill-hole PRM10-4, was oriented at 188 degrees and with a dip of -45 is 160.33 m in length. The hole encountered porphyritic and sheared rhyolite, a sheared diorite and a diabase dike. The sheared rhyolite and diorite returned anomalous gold values (up to 142 ppb).

Drill holes PRM10-5 to PRM10-7 were bored in the NNW direction (325) from the same drill site with different dips (-45, -65 and -85 respectively) and different length (224.34 m, 215.19 m and 82.74 m respectively). The three holes intersected an alternation zone of diorite, diabase and porphyritic rhyolite affected by two sheared zones. Drill-hole PPRM10-5 returned from 25.50 to 70.50 metres numerous low gold values ranging from 27 ppb to 332 ppb Au. Each intersection was 1.50 m long. The two sheared zones are almost barren. Drill-hole PRM10-6 gave values up to 604 ppb in a silicified diorite. The sheared zones are barren. A second low grade zone was intersected from 182.00 m to 195.50 m with values up to 325 ppb.

Drill-hole PRM10-7 intersected from 3 m to 79.90 metres a dioritic rock, more or less altered, which returned low gold values, up to 346 ppb. This hole was stopped in a mineralized shear zone.

Drill-hole PRM10-8 was collared about 100 metres west of the three last holes, in the same direction, and a dip of -45. This hole encountered a red diorite, more or less altered, and separated from a porphyritic rhyolite by a thick shear zone. From 72.00 to 90 metres, the core returned gold values up to 3017 ppb (3.02 g/t Au or 0.1 oz/t). An interval of 7.50 metres had an average gold value of 1.09 g/t Au.

The 2010 drilling program confirmed the presence of quartz-carbonate veins parallel to major sheared zone along the Beilby Creek with positive gold values and alteration. This break is a regionally significant fault controlling gold mineralization. The Corona and Churchill vein system extension is confirmed by holes PRM10-5 to PRM10-8, inclusive. Because of the presence of visible gold in the quartz-carbonate veins with an erratic distribution, such mineralization is difficult to intersect with wide spaced holes.

Pro Minerals will now analyze the data it has received to date in more detail, and will be utilizing its findings in planning its next phase of diamond drilling for the Shining Tree project.
