Golden Hope Confirms High Grade Intersection of 64.1 g/t Au (Gold) over 1m and Gold Deportment Study results yield up to 96.8% Gold Recovery from Gravity at Bellechasse-Timmins, Quebec.
Montreal, May 30th, 2012 /CNW/ - Golden Hope Mines Limited (TSX VENTURE: GNH) (Pink Sheets: GOLHF) � Golden Hope Mines Limited is pleased to announce the confirmation of a high grade intersection in hole BD-2011-184 from 251 to 252 meters. Although visible gold was noted in the core, previous fire assay analysis results did not detect significant presence of the gold visible in the core.
SGS Geostat had requested two separate screen metallic analysis on the rejects of the original sample from 251 to 252 meters in hole BD2011-184. The screen metallic analysis on 0.86kg of reject yielded 105 g/t Au and the remaining 0.4kg of reject returned 82 g/t Au for an average grade of 93.5 g/t Au. The original fire assay reported in a previous press release on April 18, 2012 gave 0.89 g/t Au.
Two additional fire assays on the original pulp done prior to the screen metallic analyses returned 0.22 g/t Au and 0.12 g/t Au for an average fire assay grade of 0.41 g/t Au. The weighted average of all the fire assays and screen metallic assays from this 1-metre section in hole BD2011-184 is 64.1 g/t Au.
Golden Hope is also pleased to report on a gold deportment study carried out by Dr.Tassos Grammatikopoulos, P.Geo. and Senior Process Mineralogist for SGS Lakefield on two composites samples taken from Bellechasse-Timmins.
The Gold Deportment Study was performed to determine the gold characteristics; occurrence, grain size, liberation and association with other minerals.
Samples were selected from hole BD2011-159 ("Composite Sample 1") from 30 to 33 meters interval and from hole BD2011-157 ("Composite Sample 2") from 20 to 24 meters interval with both samples having back calculated grades using the Gravity Recoverable Gold process ("GRG") of 0.49 g/t and 4.78 g/t respectively.
Length-weighted gold grams recovered from fire assay is 16.84 grams compared to 20.59 grams recovered by GRG; an increase of 22% in metal content for the compared samples. Table 1 below outlines an impressive 95.6% and 96.8% of the gold is recovered from Sample 1 and 2 respectively using the GRG process.
