Pacific Ridge Plans $3.0 Million Exploration Program on the Mariposa Property, White Gold District

March 2, 2011

Vancouver, BC - March 2, 2011 - Pacific Ridge Exploration Ltd. (TSX Venture: PEX) (the "Company") reports that preparations are well underway for its 2011 exploration programs in the Yukon. The main focus for the Company will be advancement of the Mariposa Property, in the White Gold District. A Phase 1 budget of $3.0 million is allocated for 4000 metres of diamond drilling, geophysical surveys, deep auger soil sampling, trenching and geological mapping. Contractors have been engaged for both drilling and helicopter support, and the company's technical team has been expanded.

With only 20% of the 19,000 hectare property explored during 2010, the results of 3000 soil samples collected on the Mariposa soil grid successfully identified six gold and multi-element anomalies. The largest of these targets, the 3500m long x 650m wide 'Skookum Jim' anomaly, remains open for expansion. As previously reported, the presence of gold within this geochemical anomaly has been confirmed with grab samples of rock returning up to 8.1 g/t gold and composite rock samples from trenches returning up to 1.25 g/t gold over 30 metres. Based on both the extent and tenor of these results, the Skookum Jim anomaly is a first priority drill target.

Integrated exploration activities will include both detailed follow-up of gold-in-soil anomalies, as well as initial exploration reconnaissance of the entire property area. Field work will begin in early May, with the expansion of existing camp facilities to accommodate up to 25 exploration personnel. A combination of airborne and ground geophysical surveys will be conducted over the 2010 Mariposa soil grid. Within the White Gold district, magnetic surveys have proven useful for identification of geological structures, as prospective settings for gold mineralization.

Anomalous gold and multi-element results from auger soil sampling may provide direct evidence of the presence of gold, which in this unglaciated district, can be hosted in the underlying bedrock. Infill auger soil sampling is planned to more fully define the extent of the additional five geochemical anomalies within the Mariposa grid. Trenching with a heli-portable backhoe will be conducted where results warrant. As well, reconnaissance soil sampling, prospecting and geological mapping will be directed to the yet-to-be explored 15,000-hectare portion of the Mariposa property.

Planning is also underway for exploration on Pacific Ridge's additional properties of the South Klondike-White Gold district. Airborne geophysical surveying is proposed for the Eureka Property, as well as follow-up of 2009-2010 geochemical results on the Gold Cap and Polar Stewart Properties.

With the price of copper now in the $ 4.00/lb range, the company also plans to re-evaluate its Fyre Lake Kona copper-gold massive sulphide deposit, located in the southeastern Yukon. A historical (non NI43-101 compliant) preliminary economic assessment completed in 1997 was based on a copper price of $1.00/lb.

The Fyre Lake Property is located in the Finlayson District, which also hosts the Kudz Ze Kayah (Teck) and Wolverine (Yukon Zinc) massive sulphide deposits. From the results of diamond drilling conducted by Pacific Ridge during 1996-1997, the Company outlined a NI43-101 compliant mineral resource (2006) for the Kona Deposit, which remains open to expansion. In addition to this resource, there is further exploration potential on the property, where coincident magnetic and electromagnetic geophysical anomalies remain untested.
