Expedition Mining Inc. (the "Company") is pleased to provide this update on the 2013 exploration programs within the Walker Lane Mineral Belt.
LONG CANYON PROPERTY
This property consists of 37 unpatented lode claims located 200 kms southeast of Reno and 16 kms southeast of the community of Mina, Nevada. Previous rock sampling has returned gold values up to 1.7 g/t over 3 m, and up to 9.7 g/t gold and 529 g/t silver in grab samples, and soil samples of over 1.0 g/t gold. The property hosts an extensive siliceous zone containing strongly anomalous mercury (to 155,000 ppm), antimony (to 987 ppm) and arsenic (to 2,790 ppm) values.
Structurally the Long Canyon project area is dominated by strands of the northwest trending Walker Lane Fault Zone. Arcuate splays from the main faults trend east-west 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 Bellville Mine and the deposits in the Douglas Camp.
Exploration programs carried out by the Company have identified several structural trends associated with multi-element soil anomalies. These structural zones trend dominantly north-northeast and northwest, and intersect beneath the siliceous zone which occupies the central portion of the property. The north-northeast trend is characterized by swarms of narrow quartz veins with a general northerly orientation and subvertical dip. These veins range from <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.
Compilation of the results of the Expedition programs with the historical IP data has shown that the zones of structural intersections correlate with the IP anomalies and with the multi-element soil geochemical anomalies. These areas have been chosen for the initial trenching program. Approximately 250 m (800 feet) of trenching are planned for six trenches. The trenches will be oriented perpendicular to the dominant structural trend in order to maximize exposure of the vein systems.
The Long Canyon project is situated in southeastern Mineral County and is flanked by several well known historical mining districts. The Pilot Mountains to the north have a long history of mercury production, followed by tungsten mining along the eastern edge of the range. The former producing Belleville Mine 8 kms north of Long Canyon reportedly produced around 100,000 ozs to 1939 from two quartz veins.
To the west, the Douglas Camp area was dominantly a gold and silver camp which also contained abundant scheelite and produced over $1,000,000 of tungsten during and after WW I.
To the southwest, the Candelaria District was known for high grade silver deposits which averaged 60 oz/ton in the early days of mining. By 1999 over 68 million ounces of silver had been extracted from the mines in this district.
