Employing a new geochemical technique developed by Actlabs, Golden Hope Mines has outlined a new highly prospective area at its FSG Area in Quebec, Canada.

Golden Hope Mines (TSX V: GNH) has announced that a new geochemical  technique on its new FSG Area has shown four strong gold and base metals anomalies. Previously the company had announced that it had investigated a large base metal sulphide target (3.5 km) with 8 diamond drill holes in late 2007. The Coucou is a volcanic complex with potential for VMS mineralization. Drilling intersected abundant sulphides but no economic grades of precious or base metals were found. A 2008 regional geophysical study identified a more favourable area about 3 km to the south west of the original target.

The new geochemical technique has been developed by Activation Laboratories (Actlabs) of Ancaster, Ontario, Canada.  It has come up with a soil gas hydrocarbon technique that is capable of detecting gold and base metals to depths in excess of 200 meters. Golden Hope has employed this method and located four gold and base metal anomalies in the new FSG Area and says the results are extremely encouraging.

Actlabs says that its Soil Gas Hydrocarbon (SGH) analysis has successfully shown the presence of deeply buried mineral or petroleum deposits.

 In a Canadian Mineral Research Organization (CAMIRO) project initiated in 1997, nine of ten mineral deposits were successfully detected at study sites that were specifically chosen where other geochemical methods were previously unsuccessful. The study sites included magmatic Ni-Cu sulphides, VMS, Gold, Uranium and Porphyry Copper. In the follow up CAMIRO Project 01E02, Kimberlites, IOCG, Sedex, more magmatic Cu, Ni and VMS deposit types were successful at identifying the deposit and provided a unique fingerprint.

The SGH technique involves collection of soil samples in the field and then desorbing the weakly bound heavy hydrocarbons in the C5-C17 carbon series range (pentane through to heptadecane) at the laboratory.

Using a new technology developed by Actlabs , the desorbed organic compounds are collected and introduced into a Gas Chromatograph / Mass Spectrometer (GC/MS) where over 160 of these heavier hydrocarbon compounds are measured. Heavy hydrocarbons are used instead of light hydrocarbons (C1-C4 or methane through to butane) as they are much less affected by decaying biogenic material and diurnal variability.

 SGH is also claimed to be more robust in terms of sample collection, shipping and storage conditions. Detection limits at low ppt (pg/g) levels are possible by this technology which allows background levels to be readily determined.

 Actlabs' research and development into the applicability of SGH for exploration has resulted in the availability of a cost-effective method which can be used in tandem with geophysics to improve success rates.

Weather permitting, Golden Hope will begin working on these new targets as soon as the hunting season delay is over in early November. The anomalies will be stripped, trenched, blasted and sampled.

"We are very excited about this new highly prospective area for Golden Hope Mines. The data are so encouraging that we do not want to delay our aggressive sampling program which will begin in a few weeks. We were always very interested in this particular area and we now believe that we were simply a few kilometers away from where we should have been looking all along." states Frank Candido, President of Golden Hope.
