Brixton Metals Provides Update on its Hog
Heaven Silver-Gold Project
VANCOUVER, BC – (January 15, 2018) Brixton Metals Corporation (TSXV: BBB) (the
“Company” or “Brixton”) is pleased to provide an update on its Hog Heaven project data
review and project development plans.
Highlights from the 722 holes historically drilled:
• The Hog Heaven project represents a high-grade Ag-Au-Cu-Pb-Zn underground opportunity
where gold and base metals add significant value on a Ag equivalent basis
• Hole AFR-79-5 returned 12.19m of 1,089 g/t Ag and/or 2,330 g/t Silver Equivalent for 114
percent increase when gold, copper, lead and zinc values are included as Ag equivalent
• Hole AFR-81-8 returned 54.86m of 254 g/t Ag and 411 g/t Ag equivalent for a 62 percent
increase when gold is included as silver equivalent and there is no assay data for copper, lead or
zinc
• Analysis of the intervals that were not assayed for base metals may provide additional metal
value
• Notable intercepts are 53.34m of 643 g/t Ag equivalent including 9.15m of 2,226 g/t AgEq in
Hole AFR-81-38A and 18.29m of 1,623 g/t AgEq from 106.68m including 9.15m of 2,951 g/t
AgEq in Hole AFR-79-5
A table of Silver, Silver Equivalent and 'Grams x Meters' comparison:
*Silver Equivalent values (AgEq) were calculated using the formula AgEq = $1,200 x Au g/t ÷
31.104 + $17 x Ag g/t ÷ 31.104 + $3 x % Cu ÷ 100 x 2204.63 + $1 x % Pb ÷ 100 x 2204.63 +
$1.20 x % Zn ÷ 100 x 2204.63/$17 x 31.104. This method assumes full metal recoveries. Metal
prices used in this calculation include: $17 per ounce for Ag, $1200 per ounce for Au, $3 per
pound for Cu, $1.2 per pound for Zn and $1 per pound for Pb. ** These intercepts have
incomplete assay data for Cu, Pb and Zn. True widths cannot be verified at this time.
Chairman and CEO of Brixton, Gary R. Thompson stated, “We are discovering that the Hog
Heaven project is a real gem as we dig into the historic data and are very encouraged by the
degree of high grade intercepts we have encountered thus far. One of the holes ended in 3
percent copper at about 300m depth. In addition to the treasure trove of drill data, many precious
and base metal targets as both near surface and feeder zone or root zone type targets have yet to
be drill tested. Re-logging and sampling of select historic holes and geophysical surveys are
planned over the winter months to gear up for drilling in the spring”.
Drilling Data: Brixton has completed the assay data entry and half of the drill log data entry for
the Hog Heaven project. Total metres historically drilled on the project is 57,498m from 722 drill
holes as rotary, reverse circulation and diamond drill core. Interestingly, while all of the holes
were assayed for silver and most of intervals were assayed for gold with the exception of one
hole, 68 percent of the intervals were not assayed for copper and 34 percent of the intervals were
not assayed for zinc and lead.
The Plan and Long Section Maps at the links below plot the two mineralized zones where most
of the drilling has been conducted, the Main mine zone and the Ole Hill zone. Generally, drill
depth is fairly shallow and only a few deeper holes were drilled at the Main zone. At the Main
mine 40,775m have been drilled with an average drill hole depth of 121m with the deepest hole
to 509m. The total number of drill holes at the Ole Hill zone is 380 with an average depth of 43m
with the deepest hole to 583m for a total of 16,456m of drilling. Mineralization remains open in
several directions and at depth. Most of the drilling was completed as vertical holes to define the
near surface mineralization. Hole AOR- 81-86 at the Ole Hill zone intersected 3.05m of 400 g/t
Ag or 481 g/t AgEq within 13.72m of 167 g/t Ag or 205 g/t AgEq from surface.

Note: The Qualified Person (“QP”) for Brixton cannot verify the drill results reported in the
tables above or the other technical information set out in this news release. The precise location
of the drill cores from the program is presently unknown and they have not been inspected by the
QP, and therefore Brixton has not undertaken any re-logging, re-sampling or check assays;
however, Brixton has no reason to doubt the results and considers the results relevant and
suitable for disclosure. Data from the above drill results are historical results and it is unknown
what type of quality-control programs were performed at the time. The QP also advises that true
width of the above results cannot be determined at this time.

Geology Summary: The Hog Heaven Project is located in a field of Oligocene (30.8 – 36 Ma)
volcanic and volcano-sedimentary rocks knows as the Hog Heaven volcanic field. The volcanic
rocks consist of high potassium dacite-rhyolite flow domes and dykes, ash flow deposits and
volcaniclastic rocks. These rock types intrude or unconformably overlie a basement of Late
Proterozoic Belt Supergroup strata. The volcanic suite is comprised of a flat to gently inclined
volcanic sequence, including a basal ashflow tuff unit, pyroclastic and epiclastic rocks, intrusive
and extrusive dacite porphyry, diatremes and a late trachyandesite flow. Dome and dyke
emplacement as well as Ag-Au-Cu-Pb-Zn mineralization was controlled by northnorthwest,
northeast and northwest-trending extensional faults and fractures. Mineralization is also localized
by permeability contrasts, such as the steep, north-trending diatreme breccia-dacite porphyry
contacts, within flat-lying permeable pyroclastic and epiclastic units and along the contact
between Belt strata and overlying volcanic rocks. Highest grades occur within zones of intense
silicification and acid leaching. Mineralization styles include breccia-hosted, replacement, veins
and stockworks as well as open-space fill. There is a strong vertical and lateral metal zonation
with increasing Au-Cu grades at depth. Within flat-lying ore bodies, a core of Ag +/- Au is
haloed by Pb and Zn +/- Cu.
Alteration is characterized by acid-sulphate, with widespread argillic and advanced argillic
alteration and vuggy to massive silicification. Mineral deposits at the Hog Heaven project are
classified as Ag-rich high sulphidation type.
Hog Heaven Geology Map:
Geophysical Surveys: Historical ground magnetics, VLF-EM, IP and gravity surveys were
completed and the company is in the process of digitizing and reprocessing of these data sets.
Planned work includes a deep IP-resistivity and LIDAR survey. The magnetics-VLF-EM and
LIDAR survey are expected to help identify structures that may control mineralization and
vector new zones of mineralization. The IP geophysical survey should image the known sulphide
and siliceous resistive zones and potential expansion area drill testing.
Planned Drilling: The focus for the initial 10 holes planned for the spring of 2018 shall be to
twin and confirm some of the previous drilling and to test the high-grade feeder zones to the west
of the Main mine zone and south of the Ole Hill zone. Phase two drilling will focus on
expanding the known mineralized zones, infilling areas of sparser drilling and testing some of
the nearby compelling targets. Additional holes will test newly generated targets.
Quality Assurance Quality Control: Brixton has completed assay data entry for all of the drill
holes and has developed the first 3d model for the project. The Company plans to collect and
submit the previously drilled intervals that were not assay for base metals and analyze for the full
suite of elements. In addition a select number of check assays will be analysed for comparative
purposes according to industry standards. Ongoing work includes completion of the drill log data
entry and a re-logging campaign of select cored intervals is planned. Brixton is also working
with a qualified engineering firm to convert the mine grid based historical drill data to Universal
Transverse Mercator (UTM) coordinate system.
Permitting: The Company has submitted an initial drill plan to Montana Department of
Environmental Quality. Brixton has posted reclamation bonds in the amount of USD$120,000
for its planned exploration drilling and for the transfer of the existing Operating Permit (inactive)
from the previous operator.
Resource Estimates: The Hog Heaven project does not have a NI-43-101 compliant resource
estimate. The first significant milestone for the Company will be to establish a maiden resource
on the project. The Company shall engage one or more Qualified Person’s as defined by the NI-
43-101 to author a report when it believes it has completed enough work to provide a resource
statement with enough material to generate a positive preliminary economic assessment report.
Other Exploration Targets: In addition to the Main mine and Ole Hill targets, nineteen historic
adits and workings have been identified within the area (see geology map at link above). Two of
the prospects occur at the contact between the Tertiary intrusive and volcaniclastic rocks, similar
to the Main mine. Three of the prospects occur in the Late Proterozoic Belt Supergroup rocks
which Mauk (1983) believed to be part of the Revett Formation of the Ravalli Group. Three
large gold-silver-in-soil geochemical anomalies have been identified by previous operators. Two
of these remain to be drill-tested and the third has only been tested locally. The northern soil
anomaly is located about 1.3 km north of the Main mine area and is underlain by Tertiary
volcaniclastic rocks. The southern soil anomaly is located about 1.7km SW of the Main mine
area and is located near the contact between Tertiary intrusive and volcaniclastic rocks. The
Central soil anomaly is located 200m NE from the Ole Hill area and is underlain by Tertiary
intrusive rocks and volcanic flows which also have a corresponding geophysical target. Eight
geophysical targets have also been identified within an area of 3km by 1.5km. These targets have
been defined primarily by magnetic lows occurring along the margins of gravity lows, where one
of the targets cover the Main mine area.
These targets have a northwest trend coincident with the orientation of a northwest trending
interpreted graben structure, thought to control the emplacement of dome complexes and
mineralization.
Metallurgical Work: The Company is planning to undertake additional work in order to
confirm and expand on the historical metallurgical studies conducted at the Hog Heaven project
by the previous operators. During the phase 2 exploration program, two holes for metallurgical
studies are planned.
Artificial Intelligence (AI) and Machine Learning: Brixton is adopting AI and machine
learning as part of its ongoing exploration efforts to more rapidly and efficiently advance its
exploration projects. We anticipate that by utilizing these platforms we can mitigate exploration
and development risk and build confidence in our targets and increase our chances of success
while reducing costs. To that effect, the Company is planning to work with a number of highly
regarded consultants to fully integrate the wealth of geophysical, geological, geochemical and
drilling information available for the Hog Heaven project.
