BRIXTON EXPANDS THE OBAN BRECCIA ZONE, CUTTING ONE OF THE WIDEST HIGH GRADE SECTIONS TO DATE: 150.50M OF 314.59G/T AGEQ INCLUDING 73.70M OF 466.28G/T AGEQ
Brixton Metals Corp. has completed the phase two 2012 drill
program and soil sampling program at its Thorn project, located in
northwest British Columbia. A total of 1,738 metres were drilled in 13 NQ
diamond drill holes. The depth of the holes ranged from 45 metres to 338 metres.
Additional drill results from holes THN12-81, 82 and 84 to 87, as well as
soil sample results are pending and shall be released upon receipt from
the laboratory.
Highlights:
-
THN12-83 intersected 73.70 metres of 466.28 grams per tonne silver equivalent (284.15 g/t silver, 1.49 g/t gold, 1.31 per cent lead and 1.78 per cent zinc) within a broader
interval of 150.50 m of 314.59 g/t AgEq (165.30 g/t Ag, 1.37 g/t Au, 0.92 per cent Pb and 1.25 per cent Zn);
-
Established a newly interpreted true width zone of 100 m, a depth of 300 m
and a minimum strike length of 130 m;
-
Recent drilling has expanded the high-grade mineralization at the Oban
breccia zone at depth to the south-southeast by 70 m.
Gary R. Thompson, chairman and chief executive officer, stated: "Drilling continues to
produce high-grade intercepts near surface and at depth at the Oban
breccia zone, with hole THN12-83 returning impressive gold-silver
results. The Oban zone appears to be developing into a zone with a much
larger scale potential than previously thought and clearly remains open
in several directions."
The high-grade mineralization occurs as phases of up to massive
sulphides and sulphosalts as breccia matrix. Mineralization also occurs
as disseminated, veinlet to crackle-style breccia. The dominant
minerals are pyrite, tetrahedrite, sulphosalts, sphalerite, galena and
chalcopyrite. Within the breccia matrix, these infill minerals form
layered rims around breccia fragments. The nature of the mineralization
appears to be subvertical to subhorizontal and locally structurally
controlled.
Hole THN12-83 was collared at the Oban breccia zone at an elevation of
894 m and drilled at an azimuth of 170 degrees with a dip of minus 50 degrees
to a depth of 209.70 m. Hole THN12-83 extended mineralization by
approximately 70 m in a south-southeast direction from any previously
known mineralization and established a true thickness of approximately
100 m, based on its position relative to previous intercepts. Grades are
uncut and include up to 2,650 g/t Ag and 9.21 g/t Au.

Hole THN12-80 was collared near the boundary of the Oban breccia zone at
an elevation of 915 m and drilled at an azimuth of 325 degrees with a
dip of minus 80 degrees to a depth of 166.62 m. Hole THN12-80 encountered new
mineralization to the northeast of the Oban breccia zone. Interestingly,
this new mineralization is hosted within the Thorn porphyry, which
extends beyond the Oban breccia zone.

THN12-75 to THN12-79 returned no significant results. These holes were
designed to test easterly extension of surface mineralization and were
only drilled into the Thorn porphyry to a maximum depth of 57 m;
however, based on the results encountered at hole THN12-83, the company now
realizes that deeper drilling was required to further test
mineralization at depth.
A total of 362 soil samples were collected in the drainage area of the
Amarillo Creek where a float boulder of 265 g/t Au and 631 g/t Ag was
discovered.
Corporate update
Brixton has appointed Sorin Posescu, PGeo, as vice-president of
geology. Mr. Posescu had been working for Brixton as a consulting
geologist since 2010 and brings 17 years of exploration experience to
the group. Mr. Posescu was a former project geologist for NovaGold
Resources, Sierra Geothermal Power and OMV-Petrom.
Quality assurance and quality control
Sorin Posescu, PGeo, prepared a quality assurance/quality control protocol for the company and
oversaw sampling procedures. Caroline Vallat, PGeo, from GeoSpark
Consulting Inc. conducted an independent QA/QC review, which returned
strong accuracy of the analytical results. Sealed samples were shipped
by the company geologists to ALS Minerals preparation lab in
Whitehorse, Yukon. ALS Minerals laboratories are registered to ISO
9001:2008 and ISO 17025 accreditations for laboratory procedures.
Blank, duplicate and certified reference materials were inserted into
the sample stream. Analysis for gold was done by fire assay with AA
finish. All other elements were analyzed by aqua regia digest with
ICP-AES finish. Silver overlimits were analyzed by fire assay with
gravimetric finish. Base-metal overlimits were analyzed with aqua
regia digest and AA finish. A copy of the QA/QC protocols can be viewed
at the company's website.
Silver equivalent (AgEq) values were calculated using $1,088 per ounce
of gold, $19.62 per ounce of silver, $3.20 per pound for copper, 80 cents
per pound of lead, 80 cents per pound of zinc, all with 100-per-cent metal
recoveries assumed.
AgEq equals Ag g/t plus (Au g/t multiplied by 34.98 divided by 0.63) plus (Pb per cent multiplied by 17.64 divided by 0.63) plus (Zn per cent multiplied by
17.64 divided by 0.63) plus (Cu per cent multiplied by 70.55 divided by 0.63).
Sorin Posescu, PGeo, is a qualified person as defined under
National Instrument 43-101 standards, and has reviewed and approved this
news release.
About the Thorn project
The 28,000-hectare Thorn property is located 130 kilometres southwest from the
village of Atlin in northwestern British Columbia, Canada, between the
past-producing Golden Bear mine and Chieftain Metals' Tulsequah Chief
mine development. The geology of the Thorn project straddles a bimodal
Late Cretaceous to Eocene volcano-plutonic complex, and Upper Triassic
to Middle Jurassic Stuhini Group submarine volcanic and sedimentary
rocks. The Oban breccia zone is located in the heart of a six-kilometre mineralized corridor, which is within the central portion of the
property. Brixton Metals holds a two-phase option agreement
with Rimfire Minerals Corp. (now Kiska Metals Corp.).
Brixton can earn either a 51-per-cent or 65-per-cent interest by making
cash and share payments, and incurring $5-million and $10-million in exploration expenditures respectively. Kiska may
elect to form a joint venture with Brixton at the 49/51 or 35/65 stage,
or take dilution where Brixton may increase its ownership. Brixton
shall be the operator in either case.
We seek Safe Harbor.
