Expedition Mining Provides Update on 2013 Exploration Programs on Gold Properties in Nevada

Expedition Mining Inc. is pleased to provide this update on the 2013 exploration programs on their four properties within the Walker Lane Mineral Belt, Nevada.

These properties are Long Canyon, Black Hills and Jenny Hill, all located in Mineral County and Slate Mountain located in Churchill County.


This property consists of 37 unpatented lode claims located 200 kms southeast of Reno and 16 kms southeast of the community of Mina, Nevada. Historical rock sampling has returned gold values up to 1.7g/t over 3 m, and up to 9.7g/t gold and 529g/t silver in grab samples. The property hosts an extensive siliceous zone containing strongly anomalous mercury (to 155,000ppm), antimony (to 987ppm) and arsenic (to 2,790ppm) values. A soil geochemical survey was carried out over the Long Canyon South block in January, coincident with a preliminary mapping and rock sampling program. The exploration target on the Long Canyon project is high grade structurally controlled mineralization.

This work has identified several structural trends associated with multi-element soil anomalies. These structural zones trend dominantly north-northeast and northwest, and intersect beneath the extensive siliceous zone which occupies the central portion of the property. This siliceous cap contains generally low gold values, and is believed to represent the uppermost level of the hydrothermal system. The gold bearing veins are only exposed at lower stratigraphic levels in the drainages.

The north-northeast trend is characterized by swarms of narrow quartz veins with a general northerly orientation and sub-vertical dip. These veins range from less than 1 cm to greater than 1 m in thickness. At least two of these NNE zones have been identified to date. Veins within the NW trending zone show a greater variation in dip attitude from -45 to vertical, and are generally oriented sub-parallel to the overall Walker Lane Belt. The vein widths within the northwest trend are similar to those in the NNE set.

Structurally the Long Canyon project area is dominated by strands of the northwest trending Walker Lane Fault Zone. Walker Lane structures, and arcuate splays from the main faults, trend across the property and are exposed in many of the drainages. The northerly trending structures extend through the Pilot Mountains to the north, and are covered by pediment fans to the south. The intersections of these structural zones are believed to be important localizing features for the mineralization encountered at the Belleville Mine and the deposits in the Douglas Camp.

Rock sampling from the current program has confirmed the values reported by earlier sampling and includes up to 1.16g/t gold over 5 m within a shear zone. Final assays are expected from the soil survey by the end of February. Compilation of the mapping, geophysical data and rock sampling information, is expected to provide targets for the next phase of work which will require mechanical trenching to expose the anomalous zones for systematic channel sampling.


A total of 2,041 samples were collected during the recently completed soil geochemical survey on Black Hills. The Jenny Hill soil grid is located 2 kms to the northeast of the Black Hills project and consisted of 478 soil samples. The Slate Mountain soil grid consisted of 705 samples on the east flank of Slate Mountain, approximately 10 kms north of Black Hills. The Company is still awaiting final gold assays, however several significant areas of multi-element anomalies have been outlined on all grids. These projects are all located within the Walker Lane Belt and in proximity to the operating Rawhide Mine.

"The Company continues to be encouraged by the results we are receiving from our four Nevada gold properties. We look forward to the completion of our mapping, rock and soil sampling programs and moving forward with further exploration to bring one or more of these properties to the drill-ready stage in the very near future. The Company is sufficiently funded for further 2013 exploration and a phase one drill program should the Company deem it prudent," states Ron Atlas, President and Chief Executive Officer.

Expedition's disclosure of a technical or scientific nature in this press release has been reviewed and approved by James Chapman, P.Geo, who serves as a qualified person under the definition of National Instrument 43-101.
