Brixton Metals Corporation (TSXV:BBB) is pleased to provide an update on its Hog Heaven project data review, new geophysical data acquisition and short term project development plans.
Highlights from the work to date at the Hog Heaven project:
- Completed the historical assay data entry and drill log data entry. Total metres historically drilled on the project is 57,498m from 722 drill holes as rotary, reverse circulation and diamond drill core
- Completed 724 line kilometers VTEM Plus and horizontal magnetic gradiometer survey
- Completed the acquisition of 60 square kilometers of Lidar and digital aerial photography
- Received the exploration/drilling permit from Montana Department of Environmental Quality
- Renewed the operating permit with Montana Department of Environmental Quality
- Construction of a new core facility has been completed
- Brixton funded 2 M.Sc. research studies with Montana Tech University to look at alteration and ore mineralogy to further understand the hydrothermal fluid system to provide vectors for feeder zones of the mineralization
Chairman and CEO of Brixton, Gary R. Thompson stated, “The Hog Heaven project, which hasn’t seen any work since the mid-90s, is now drill ready. The project represents a high quality high-grade asset that we rarely see available in the market these days. The initial drill programs should focus on infill and confirmation drilling to support a NI-43-101 resource estimate and to confirm the presence of new mineralization on the property. Targets include near surface high sulphidation high-grade polymetallic-silver-gold rich veins and breccia, which is believed to be related to a porphyry target at depth. We are excited to drill some fresh core on the project.”

Drilling
Brixton is planning to initiate a nine hole drill plan for the fall of 2018 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. The proposed drilling program is subject to future financing.

| 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, resampling 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. | |||||
Geophysical surveys:
During May 2018, Brixton contracted Geotech Ltd. to carry out a helicopter-borne geophysical survey over the project. A total of 724 like-kilometers of geophysical data were acquired and consisted of Versatile Time-Domain (VTEM) Plus and horizontal magnetic gradiometer surveys.
The survey has been successful in identifying several magnetic and EM anomalies. It was observed that generally, known mineralization is located along magnetic low margins. Brixton is planning to drill test some of the magnetic anomalies, with the objective to identify additional high grade Ag-Au-Cu-Pb-Zn mineralization as well as testing for porphyry mineralization potential of the project.
Exploration Upside:
Main Mine Zone
The Main Mine zone is the most advanced target at the Hog Heaven Project and where most of the historical work was undertaken. The mineralization consists of Ag-Au-Cu-Pb-Zn mineralization that occurs at the contact between latite porphyry and volcanoclastics. There is a strong vertical and lateral metal zonation with increasing Au-Cu grades at depth within flat-lying ore bodies and a core of Ag +/- Au is haloed by Pb and Zn +/- Cu. The Main Mine zone was subject to a positive feasibility study produced by Coca Mines in 1988, but the mine construction was halted due to silver and gold prices dropping in 1990 (see News Release dated June 22, 2017). The Main Mine zone presents excellent exploration upside near surface as well as at depth (feeder zone).
Ole Hill Zone
Historically, mineralization has also been outlined in the Ole Hill area and occurs along the contact between, and within, both volcanoclastics and Precambrian siltites. Generally the gold content is higher at the Ole Hill zone than the Main Mine zone. Brixton is planning to drill test the extent of know mineralization at depth and on strike (some of the historic drillholes ended in mineralization).
Other Exploration Targets: In addition to the Main Mine and Ole Hill targets, nineteen historic adits and workings have been identified within the area. 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.
