Colorado Resources Ltd. has announced the results of the 2011 exploration programs on its 100% owned Heart Peaks Property in northern British Columbia. The 14,396 hectare Heart Peaks property is located 45 kilometres northeast of the past producing Golden Bear Mine.
Work completed on the Heart Peaks property includes:
- The collection of 209 rock samples and 11 soil/silt samples
- Preliminary geological mapping and detailed prospecting
- Re-logging and sampling of historic drill core
- 977 kilometres of Helicopter-borne EM/Magnetic surveying
- Detailed PIMA alteration studies of historic drill core
- Aster Imagery study
- Acquisition of 5,588 hectares of new mineral tenures added
The Heart Peaks Property covers rhyolitic volcanic centres, phreatic breccias and flow domes that occur along a north trending three kilometre wide by five kilometre long graben structure. Widespread argillic alteration with pyrophyillite occurs over a 3 kilometres square area and includes local areas of silicification, opalization and the presence of alunite with associated anomalous levels of gold, silver, antimony, mercury and arsenic.
The Heart Peaks property hosts both low and high sulphidation epithermal gold mineralization occurring both in high grade quartz veins in a geological setting similar to Newmont's Midas Mine in Nevada and in lower grade bulk tonnage environments, such as at Newmont's Yanacocha Deposit in Peru.
Two areas of high grade epithermal gold and silver mineralization have been located on the property. Rock grab sample results from the Top Zone reported assay values up to 31.6 g/t gold and 4282 g/t silver. A second previously unknown zone, located 1.2 km southeast of the Top Zone returned grab sample values of 4.7 g/t, 8.5 g/t and 10.4 g/t gold, with 23 g/t, 60 g/t and 32 g/t silver, respectively.
Preliminary evaluation of the 2011 airborne geophysical data indicates that the two known gold and silver mineralized zones are associated with a 700 m x 2500 m long resistivity feature that extends beyond the areas of known mineralization. Several additional, strong resistivity features occur on this large property and require additional follow up work to evaluate their potential.
Aster Imagery completed by Ward Kilby, P.Geo., of Cal Data Ltd. for Colorado on the Heart Peaks property identified several distinct colour anomalies described as indicating the presence of jarosite, kaolinite and quartz and will also require detailed follow up.
PIMA alteration studies by Kim Heberlein, P.Geo., on 11 select samples of historic drill core and 34 grab samples identified the presence of illite, smectite, kaolinite, dickite, jarosite, NH4 species and probable silica. This suite of minerals confirms that the property is in a favourable geological environment for the development of epithermal gold mineralization and will help to vector subsequent exploration.
Adam Travis, Colorado Resources President & CEO states, "I am very pleased that we were able to acquire this large alteration system in northern British Columbia by staking. Through a multi-faceted approach of airborne geophysics, alteration mapping and good old-fashioned boots on the ground prospecting we were able to identify areas which are returning values up to 1 oz/t Au and have also found new areas of mineralization. I believe this type of target has been overlooked in northern BC and if it were located in Nevada, it would have had hundreds of drillholes into it by now. I'm looking forward to an exciting program next year culminating in drilling."
