Bralorne Reports Higher Gold Output for March 2014 and Outlines New
Mining Block Averaging 12 g/t Gold
VANCOUVER, BRITISH COLUMBIA--(Marketwired - May 27, 2014) -
Bralorne Gold Mines Ltd.
(TSX-VENTURE:BPM)(OTCQX:BPMSF)(FRANKFURT:GV7)(BERLIN:GV7) (WKN
A0B75M) (the "Company") is pleased to report another month of
increased gold output at the Company's 100% owned Bralorne Gold
Mine located near Gold Bridge, British Columbia, Canada. During
March 2014, 2,755 tonnes of material was processed through the
Company's 100 ton-per-day mill at an average grade of 9.7 g/t for
total gold output of 758.7 ounces. This represents a 41% increase
compared to February 2014. In addition, underground development
work outlined a new potential mining block with a strike length of
68 metres averaging 12 g/t gold.
Dr. Mathew Ball, President and Chief Operating Officer, stated:
"We are very pleased with the significant increase in gold output
seen in March, which was the result of higher grade material in the
areas being mined. This increased productivity supports our
intention to double current mill capacity with the goal of reaching
commercial production. We are also pleased to see continued
exploration upside in the BK-3 zone, where the new mining block
appears to be open to the west."
Milling Results for March 2014
For the month of March 2014, the company operated 31 days and
processed a total of 2,755 tonnes of material grading 9.7 g/t Au.
Gold output totaled 758.7 ounces, including 379.9 ounces of gravity
recovered gold and 378.8 ounces of gold contained in flotation
concentrate. Mill throughput averaged 90 metric tonnes per day
operated and gold recovery was 89%. March production was
significantly higher than February as a result of higher grade
material in the areas being mined (see table below).

Underground Mine Development
Stope mining and development of new mining blocks continued in
the BK-3 zone of the Bralorne mine. A second raise was driven on
the western zone from a point situated 24 metres west of the first
raise. The new raise extended 32 metres above the 3900 west
sub-drift. Significant assay results were obtained in the lower 16
metres of the raise, where an average gold grade of 15.7 g/t over
0.6 metres width was encountered in the vein (assays above 103 g/t
cut to that value). Over a mining width of 1.5 metres, the average
grade is 6.6 g/t gold. The upper half of the raise exposed a weakly
mineralized vein and assay results were not significant over a
minimum mining width of 1.5 metres.
Additional sampling was conducted along the roof of the western
3900 sublevel where the vein contains visible gold; however,
initial assays were low grade. Including these new assays, which
were higher than previous, the revised average grade of the
sub-drift is 59.3 g/t over 0.9 metres in width for a strike length
of 68 metres (assays above 103 g/t cut to that value). Over a
minimum mining width of 1.5 metres, the average grade is 14.4 g/t
gold. Of note is that the last sample at the western end graded
23.7 g/t gold over 1.6 metres, suggesting that the zone extends
further west where exploration has not been carried out.
The overall average grade of the sub-drift and two raises is
50.9 g/t over 0.7 metres in width (assays above 103 g/t cut to that
value). Over a minimum mining width of 1.5 metres, the average
grade is 12.0 g/t gold. The area represented by this development is
68 metres in strike length and 15 metres in height. This new block
is now being prepared for mining.
Quality Assurance/Quality Control
Gold recovery is reconciled to gold contained in flotation and
gravity concentrates. Flotation concentrate assays are performed at
ALS Laboratories in North Vancouver, British Columbia - an
accredited independent laboratory with quality monitored by
internal standards. Check samples are done on composite samples
collected by AH Knight and assayed by ALS Laboratories in North
Vancouver, British Columbia, and umpire assays are performed by
Alex Stuart Limited in Knowsley, England. Gold contained in gravity
concentrate is reconciled from settlement assays received from the
refiner. Check assays are performed on duplicate samples of gold
doré by ALS Laboratories in North Vancouver, BC.
QA/QC protocols followed for underground samples include
monitoring the results of blank and standard samples inserted at a
frequency of 1 in 20 each, and re-analysis of check samples at a
second laboratory. Underground samples are submitted for
preparation and analysis at SGS Laboratory in Burnaby, BC, which is
ISO certified and accredited. Gold analyses are conducted on 1
assay-ton aliquots using the fire assay method with a gravimetric
finish. Metallic sieve assays are done on all mineralized vein
samples.
The Company cautions that it has not completed a feasibility
study based on mineral reserves. The Company is proceeding with
operations based on mineral resources, which are not mineral
reserves and do not have demonstrated economic viability. The
project therefore has a higher risk of economic or technical
failure. The mill is being operated to generate incidental revenue
from the sale of gold doré bars and flotation concentrate to offset
exploration and development costs. The Company plans to continue
milling as resources are developed and will increase the milling
rate if and when sufficient resources are defined.
