Geoscience BC Releases Report 2011-3: The Application of Surface Organic Materials as Sample Media over Deeply Buried Mineralization at the Kwanika Central Zone, North-Central BC

 Geoscience BC is pleased to announce the release of Geoscience BC Report 2011-3 "The Application of Surface Organic Materials as Sample Media over Deeply Buried Mineralization at the Kwanika Central Zone, North-Central British Columbia" by D.R. Heberlein and C.E. Dunn.

This report is now available for download through Geoscience BC's website at www.geosciencebc.com/s/DataReleases.asp.

As a follow up to the 2009 Geoscience BC study by Heberlein and Samson (2010), the authors carried out an expanded geochemical orientation survey over the Kwanika Central Zone focusing on the geochemical responses in organic materials to the mineralization. Results of the original study showed that the most effective combination of sampling medium and chemical extraction for detection of the deeply buried Cu-Au porphyry mineralization was Ah horizon soil with a modified aqua regia (ultratrace) digestion with ICP-MS determinations. This report further investigates the use of Ah horizon by comparing sampling results from an offset 100 by 100 metre grid with other organic materials, namely vegetation and charcoal.

This release includes a report (PDF format), quality control and summary statistics (Excel files) and original analytical results (CSV and Excel files). The report is the final project deliverable for GBC Project 2010-003, and was the focus of a technical presentation by D. Heberlein at the 2011 AME BC Mineral Exploration Conference in January. More information on this project, including a report on the preliminary project results published last month in Geoscience BC's Summary of Activities 2010 volume, can be found at www.geosciencebc.com/s/Proj2010-003.asp.
