VANCOUVER, BRITISH COLUMBIA (TSX: AMM)(AMEX: AAU) is pleased to
announce that it has received a report detailing the metallurgical
performance of ore samples from its 100% owned Elk gold property,
located near Merritt, British Columbia, Canada. Average gold
recoveries of 95% were achieved using a gravity plus cyanidation
flowsheet over a range of head grades.
The tests, which examined feed grades between 5 and 47 g/t gold,
were carried out by G & T Metallurgical Services Ltd. ("G &
T") of Kamloops on diamond drill core recovered during the 2007
season. G & T is an ISO 9001:2000 accredited laboratory and
work was conducted under the supervision of Mr. John Folinsbee,
P.Eng.
A single gravity plus flotation test achieved a gold recovery of
95% also. Additional flotation tests may be necessary to confirm
this result is representative of the expected performance of a
gravity plus flotation flowsheet. Silver recoveries of 86% were
reported using the gravity - cyanide flowsheet, although a silver
resource has not yet been calculated for the property.
The Elk deposit hosts a number of parallel, narrow, high grade
quartz veins. Strike continuity of 950 metres has been established
on one of these veins. Trial mining in the early 1990's recovered
16,500 tonnes grading 97.03 g/t Au, containing 51,460 ounces of
gold by open-pit and underground mining methods.
A summary of the mineral resource estimate at Elk, as detailed
in the 2007 SEDAR filed Technical Report is as follows:
