VANCOUVER, Feb. 20 /CNW Telbec/ - Endurance Gold Corporation
(EDG - TSX.V) announces that the results from an extensive program of
additional cyanide leach and screen fire metallic gold analyses on samples
collected during the summer 2007 diamond drilling program on the property
provide results which encourage continued exploration for a large-tonnage
low-grade gold system associated with basal Proterozoic quartz-pebble
As reported earlier (See EDG News Release 07-19), a total of 407 samples
were split and analyzed for gold by Fire Assay ("FA"). Of these, 326 samples
were of pyritic basal quartz pebble conglomerate, the target horizon of the
diamond drilling program. The average composite gold grade of the 326 samples,
which totaled 313.86 metres, was 405 parts per billion (ppb), or 0.405 grams
per tonne (gpt).
To determine the amenability of the mineralization to leaching and to
evaluate the "nugget effect" of this newly discovered gold prospect, 317 of
the above 326 samples were also subjected to Total Cyanide Leach ("TCL"). TCL
samples were crushed and pulverized to -150 mesh and leached for 24 hours. The
TCL technique does not typically report full recovery of the gold since it is
a measure of the amenability of the mineralization to simple free-milling
metallurgical processes. An average grade of 0.392 gpt was reported for the
317 samples, or approximately 95.8% of grades reported by the standard FA
technique. These results provide a preliminary indication that the gold can be
readily liberated from mineralized conglomerates through simple crushing,
grinding, and cyanide leaching. Furthermore, the relative differences between
the two analytical techniques are within an acceptable range of variance, thus
the cost effective Standard FA analytical technique can be used with
confidence as the company moves forward.
The Company also submitted 40 selected samples which initially returned
in excess of 250 ppb gold, using the FA procedure, for Screen Fire Metallics
("SFM") analyses. The SFM method analyzes various size fractions of crushed
and pulverized sample material, to determine if relatively coarse free gold is
present. The results of the SFM analyses averaged 1.267 gpt gold, versus
1.141 gpt by the FA technique, and 1.167 gpt by the TCL technique. The
increase of approximately 11.0% in SFM results from the FA results suggest the
presence of free gold within the conglomerate horizon. A program of
petrographic thin and polished section work is underway to assist in
understanding the nature of gold mineralization in the conglomerate.
Duncan McIvor, President and CEO of Endurance, stated "These results are
positive for the Company, indicating that we have identified a significant new
style of near surface gold mineralization in Canada within a mineralogical
environment that has potentially favourable metallurgical characteristics if a
deposit of sufficient gold grade and size can be discovered. Both the SFM and
to a lesser extent the TCL results indicate there is a nugget effect, or the
very encouraging presence of coarse free gold, within the conglomerates.
Equally important is that the Total Cyanide results suggest the gold is
readily liberated from the pyrite mineralization within the conglomerates, and
is not lattice bound and/or refractory in any way. These results, the
proximity to surface of the mineralization, and the area covered by surface
gold samples exceeding 0.5 gpt, all point to the potential for the discovery
of a large open pit gold deposit. We look forward to commencing an aggressive
2008 drill program."

for a major 2008 summer diamond drilling program is underway.
