The British Columbia Geophysical Society will be hosting a one day Economic Geology for Geophysicists course on May 6th. The course, provided with generous support from Geoscience BC and UBC Mineral Deposit Research Unit, is aimed at providing economic geology background for geophysicists and all exploration geoscientists. The information presented will provide a framework to help the integration and communication of exploration techniques.
Economic Geology for Geophysicists
Thursday, May 6th
UBC Robson Square Room 483
BCIT, Downtown Campus
555 Seymour Street, Vancouver
Course presenters include Thomas Bissig (MDRU), Craig Hart (MDRU), Dianne Mitchinson (MDRU), Steve Rowins (BCGS), Claire Chamberlain (Teck), Lucas Marshall (Teck), and Sean McKinley (Cambria Geosciences Inc).
Topics that will be covered include: tectonic settings, host rocks, structure, emplacement, alteration, mineralization and the relation and comparison between various deposit models. Deposit types to be discussed include porphyry deposits, Archean gold, intrusion-related gold, epithermal gold, VMS, SEDEX/MVT/sediment-hosted copper, and IOCG deposits. Physical properties will be considered!
QUEST-South Project in British Columbia includes a new airborne gravity survey (Sander Geophysics) which covers 45,000 square kilometers between Williams Lake and the USA border. The airborne gravity digital data, grids and final technical report can be downloaded at Geoscience BC QUEST Project Data Releases. This gravity survey involved more than 25,000 line kilometeres of data at a 2 km line spacing.
The QUEST-South Project is focused on the Quesnel Terrane, south of Williams Lake, and will provide new geoscience information over an area of 130 000 km2. The QUEST-South airborne gravity survey was under taken by Sander Geophysics using their aiborne inertially referenced gravimeter (AIRGrav). This region of the province has been explored and mined for decades and remains one of the most actively explored and prospective areas for discovery of new Cu, Mo and Au resources in British Columbia.
In 2006 GoldSource Mines Inc. completed an airborne EM geophysical survey (Fugro Airborne) for diamond exploration. In April 2008 while drilling geophysical anomalies for diamonds, Goldsource Mines Inc. intersected approximately 23 metres of coal in two discovery drill holes. Now the company has re-processed the 5,700 line kilometres of EM geophysical data in an effort to delineate the aerial extent and the thickness of potential coal zone occurences.
December 10, 2009 ‐ Goldsource Mines Inc. announces that it has entered into an agreement with Westcore Energy Ltd. pursuant to which Goldsource has agreed to apply its proprietary geophysical matrix to Westcore’s Fugro airborne geophysical data and to provide Westcore with specific drill sites on its Saskatchewan and Manitoba coal lands which, in the opinion of Goldsource, will have a high probability of intersecting significant intervals of coal. Goldsource has completed a significant amount of work and incurred considerable expense since its original Border coal discovery in April of 2008 in developing a proprietary geophysical matrix applicable to Fugro airborne geophysical data which provides a “signature” for prospective coal deposits based on a correlation between airborne geophysical data analyses, down‐hole electronic logs and geological ground proofing through drilling.
As consideration, Westcore will initially issue 100,000 common shares to Goldsource. In the event that Westcore is successful in drilling at least one intercept consisting of not less than 10 metres of coal on each of two drill targets identified by Goldsource (“Success Criteria”), the following additional conditions will apply – Westcore will issue an additional 1.0 million common shares to Goldsource…
According to the latest survey results for exploration and deposit appraisal projects across Canada (October 2009) and Australia (September 2009) mineral exploration continues to decline despite a global recovery in commodity prices.
