Wallbridge Mining Confirms Copper, Gold and Molybdenum Mineralization on Miocene Metals Spin-out Properties

Toronto, Ontario - August 12, 2010 - Wallbridge Mining Company Limited ("Wallbridge" or the "Company") (TSX: WM) today announced that prospecting and initial sampling by its subsidiary, Miocene Metals Limited, have yielded high-grade copper values ranging up to 23.40% copper and elevated gold values up to 1.65g/t gold from chip and grab samples collected on the Mackenzie property along a structure that has been traced over a horizontal distance of approximately 1,000 metres.

Bruce Jago, President and CEO of Miocene Metals stated that "The results of this early sampling demonstrate that our exploration model in this under-explored porphyry belt is valid. We are very pleased that outcrop sampling on the Mackenzie and Salal properties has confirmed the presence of copper-gold and molybdenum mineralization, respectively. We look forward to a very active late summer and fall exploration season."

Copper, gold and molybdenum mineralization has been discovered on three of the eight British Columbia properties; Rogers Creek, Salal and Mackenzie. In addition, anomalous gold and copper results were obtained from a stream sediment program on four other properties. Results from chip and grab sampling on the Mackenzie Property are as follows:

Porphyry-style molybdenum mineralization was confirmed in the Mud Lake area of the Salal property, which is located about 10 kilometres south of Mackenzie. Re-sampling of known molybdenum showings in the northern part of the property returned values up to 3.24% Mo and 3.55 g/t Re confirming the rhenium-enriched nature of molybdenum mineralization on the property as indicated by historical sampling. Historic sampling has discovered molybdenum mineralization along a 15 kilometre arc, which traces the contact between an inner coarse-grained and outer fine-grained phase of the host granodiorite. Continued summer exploration work includes drilling targets on the Rogers Creek, Salal and possibly the MacKenzie properties.

Stream Sampling Results:

Stream sediment sampling was carried out on three other properties, the Mount Barr, Custer Ridge, and Sunshine Properties. The sampling has identified several areas with anomalous gold, copper and molybdenum values. Values on the Mount Barr property range up to 0.86 g/t Au, 120 ppm Cu and 18.75 ppm Mo; values on the Custer Ridge property range up to 2.3 g/t Au; and a single anomalous silt result (0.22 g/t Au) was obtained from the core of the Sunshine property, which will also be followed up. At Shulaps Property, near Lillooet, a number of anomalous gold, (up to 0.393 g/t Au) copper (up to 104 ppm Cu) and molybdenum (up to 11.0 ppm Mo) values were obtained from streams in the northern half of the property, one supported by a cluster of three medium level copper anomalies.

Stream sediment and rock samples were delivered directly to ALS Chemex Ltd. Laboratories in Vancouver for preparation and analysis. Rock samples were crushed to 70% passing 2 mm, after which a split was taken with a riffle splitter and pulverized to 85% passing 75 microns. The samples were then analyzed for 48 elements using Chemex's ME-MS61 package, which is an inductively-coupled plasma mass spectrometry (ICP-MS) method utilising a near total four acid digestion. The samples were assayed for Au by standard lead collection/fire assay fusion (Au-ICP21) using a 30 gram pulp split and an inductively coupled plasma atomic emission spectrometry (ICP-AES) finish. Silt samples were screened to minus 200 microns, and analysed by the same techniques as described above for the rocks.

About the Companies

Wallbridge Mining Company Limited's primary focus is the exploration for platinum group element ("PGE"), nickel, and copper deposits in the Sudbury area of Ontario. The Sudbury area hosts the world's largest concentration of nickel deposits and is currently the most active mining camp in North America. Major joint venture partners in Sudbury include Vale Inco, Xstrata Nickel, Lonmin Plc and Impala Platinum Holdings Limited. Wallbridge also has a major shareholding in Duluth Metals Limited, which has defined a large copper-nickel-PGE resource in the rapidly emerging Duluth Complex base metal camp in Minnesota.

Miocene Metals Limited is a spin out company from Wallbridge which will be focused on exploration for and development of copper-gold-molybdenum resources in southwestern British Columbia within the Cascade Magmatic Arc.
