Overview:
The Silverthorne property is located in The Walker Lane Trend 20 miles north of Hawthorne, Mineral County, Nevada. An area that has historically yielded several multimillion ounce gold & silver deposits including Round Mountain, The Comstock, Tonopah & Goldfeild. The Walker Lane trend is reported to have produced 500,000,000 ounces of silver & 25,000,000 ounces of gold.
Geological:
The general Geology of the Silverthorne Property consists of structurally controlled, silver dominant, polymetallic system with the potential to hold very high grade silver & silver gold deposits.
Exploration:
Exploration planning on the Silverthorne Property is underway. Initial sampling done by Charles Sulfrian, P.Geo., VP Exploration returned values of gold 27.8 grams per tonne ("gpt") (0.81 troy ounces per ton ("opt")) and silver 3,130gpt (91.29opt) from target area 1. Terraco’s assay determinations for gold and silver were by 60 gram Fire Assay [detection limit of 0.003 opt gold and 0.1 opt silver]. All assays, repeats and check assays were provided by American Assay Laboratories of Sparks, Nevada.
The property vendor ("MSM") had 62 samples taken throughout the Silverthorne Property in March and April 2006. From the sampling and mapping, there appear to be three principal areas of alteration and metallization.
The first target area is a silver-lead enriched zone where silver assays of rock samples taken by the previous vendor included values from trace to as high as 17,635 gpt (514.41 opt) silver and 0.664 gpt (0.0194 opt) gold.
Rock samples collected from a second area (a gold-copper enriched zone) returned gold values from trace to a high of 0.939 gpt (0.0274 opt) gold.
The third target area sampled yielded gold assays from trace levels up to 0.893 gpt (0.026 opt), together with silver values to highs of 74.9 gpt (2.18 opt) and 91 gpt (2.65 opt) silver (analyses were performed for MSM by ALS Chemex of Sparks, Nevada). |
