Brixton Metals Discovers Porphyry Style Mineralization at the Camp Creek Copper Corridor and Drills 230.82m of 0.27% CuEq at its Thorn Project
VANCOUVER, British Columbia, Dec. 19, 2019 (GLOBE NEWSWIRE) — Brixton Metals Corporation (TSXV: BBB) (OTCQB: BBBXF) (the “Company” or “Brixton”) is pleased to announce final analytical results from its 2019 phase two exploration program at its wholly owned Thorn Project located in the Golden Triangle of British Columbia. The analytical results reported below are from a total of ten core holes, which is the balance of the 2019 program. Six core holes were drilled at the Chivas Porphyry target, two core holes were drilled at the Camp Creek Copper Corridor Porphyry target, one core hole was drilled at the Talisker Zone and one core hole at the Outlaw Zone, a sediment hosted gold target.
2019 Highlights:2019 drilling further supports a district-scale opportunity at the Thorn Project, showing metal zoning similar in scale and arrangement with large porphyry Cu(Au-Mo) systems worldwideIntersections of porphyry-style Cu-Au-Mo mineralization in multiple 2019 drill holes in the Camp Creek Corridor:THN19-150 (Oban): 554.70 m at 1.97 g/t AuEq (97.00-651.70 m)THN19-151 (Oban): 256.87 m at 2.31 g/t AuEq (100.18-357.05 m)THN19-162 (Glenfiddich): 230.82 m at 0.27% CuEq (323.00-553.82 m)
Drill hole THN19-162 intersected Cu-Au-Ag-Mo mineralization as follows:230.82m of 0.16% Cu, 0.08 g/t Au, 0.011% Mo and 1.90 g/t Ag or 0.27% CuEq from 323.00m depth with increasing Cu and Mo grades at depthIncluding 91.00m of 0.21% Cu, 0.09 g/t Au, 0.015% Mo and 2.43 g/t Ag or 0.35% CuEq from 425.00m depth Including 59.25m of 0.22% Cu, 0.11 g/t Au, 0.015% Mo and 2.59 g/t Ag or 0.38% CuEq from 456.75m depth
Further drilling at the Outlaw Zone confirms broad intervals of gold mineralization:Drill hole THN19-160 intersected 32.05m of 0.50 g/t Au from 23.95m depth including 2.00m of 5.01 g/t Au from 54.00m depthDrill hole THN19-159 intersected 37.78m of 1.23 g/t Au from 95.00m depth including 12.00m of 3.46 g/t Au (gold assays adjusted after screen metallic analysis)Chairman and CEO of Brixton Metals, Gary R. Thompson stated, “The 2019 exploration season for Brixton was an exciting one, which started with one of the deepest and best core holes ever on the Thorn Project resulting in more than a half kilometre of mineralization. Drill hole 150, which was drilled at the Oban diatreme, included 135.96m of 5 g/t AuEq. Drill hole 162 was collared 1 kilometre west of hole 150 and is the first porphyry style mineralization that has been drilled in the Camp Creek area. We are encouraged that the grades in hole 162 are increasing with depth and ended in mineralization. The Camp Creek Copper Corridor has all the porphyry hallmark indicators of a large mineralized system. The Camp Creek target is a buried porphyry target that will take more work including geology, geophysics, geochemistry and deep drilling to locate the center of the system.” See Figure 11 which shows the current work area in relation to the size of the claim block. Mr. Thompson continued, “Following the recent financings, Brixton expects to finish the year with about C$5.6 million and is well positioned to continue advancing Thorn along with its other projects for the benefit of our shareholders. We are still reviewing the data from the 2019 work programs at all of our projects and plan to release our 2020 exploration plans early next year.”Thorn Project Porphyry Target Highlights:Multiple phases of texturally and chemically Cu-fertile porphyry phases are present. Textural favourability is indicated by ‘crowded’ plagioclase and hornblende phenocrysts and thick biotite books; chemical fertility by high Sr/Y ratios, a recognized signal of porphyry Cu-related intrusions worldwide.
High-grade veins containing enargite and/or other sulphosalts are common in parts of the Camp Creek Corridor like drill hole THN13-121, which returned 1.1 m true thickness of 10.62% Cu, 583 g/t Ag and 2.55 g/t Au from 74.4m depth. Vein grab samples from Camp Creek have returned up to 66 g/t Au, 32.8% Cu and 2,900 g/t Ag; however, these grab samples are not representative throughout the property, but similar veins closely overlie porphyry Cu shells at other deposits.
Fragments containing chalcopyrite-and/or molybdenite-mineralized porphyry-style veins are present in the Oban breccia. They were likely derived from porphyry mineralization at depth and transported upward by the explosive brecciation process (Sillitoe, 1985).Click here for Figure 1. Drill Location Plan MapCamp Creek Copper Corridor Drilling Summary The 2019 phase two program objective was to conduct a deep seeing to about one kilometre depth DCIP-MT geophysical survey across the Camp Creek trend to identify drill targets. Unfortunately, due to a late start of the survey and the early onset of winter conditions, less than half of the proposed survey lines were completed (9km of the 20km). Drilling at Camp Creek Target consisted of a total 1,308m within three holes with the objective to test for porphyry related mineralization. Drill hole 162 was located about 1 kilometre west from hole 150. Hole 162 was successful in intersecting porphyry style copper-gold-molybdenum-silver mineralization over significant widths. Mineralization is hosted in a diorite porphyry Thorn stock and consists generally in disseminated sulphides. Drill hole 162 was drilled below the high sulphidation part of the system that was intersected by previous drilling at the Glenfiddich Zone where THN13-121 returned 1.1 m true thickness of 10.62% Cu, 583 g/t Ag and 2.55 g/t Au from 74.4m depth.Click here for Figure 2.

HQ Core THN19-162, From 406.95m to 416.66m DepthThe most significant porphyry related mineralization interval in drill hole 162 occurs from 323.00m to 553.82m where analytical results returned 230.82m of 0.16% Cu, 0.08 g/t Au, 0.011% Mo and 1.90 g/t Ag or 0.27% CuEq. Importantly, it appears that porphyry style Cu-Mo mineralization increases with depth (see Figure 6. Hole 162 Graphic Log).Table 1a.

Camp Creek Cross SectionDrill hole 161 was drilled at the Talisker Zone and was designed to test for down-dip extension of the gold-copper-silver mineralization intersected in hole THN11-51 (News Release dated October 25, 2011: THN11-51 intersected 49.78 m of 1.41 g/t Au, 19.0 g/t Ag and 0.25% Cu or 2.26 g/t AuEq.) Best mineralized interval in hole 161 was 14.00m of 0.17 g/t Au from 30.00m.Table 2. Composite Assays for THN19-161All reported assays are uncut weighted averages and represent drilled core lengths. The true width of reported mineralization is unknown at this time.Drill hole 163 was designed to test a high chargeability anomaly delineated by the fall 2019 TITAN 24 DCIP Survey conducted in the Camp Creek area. The hole intersected gold-silver-zinc mineralization, which is hosted mainly in a matrix rich diatreme breccia unit and consists of sulphides as disseminated or veins. Highlights of the analytical results from hole 163 are shown in table below.Table 3. Composite Assays for THN19-163All reported assays are uncut weighted averages and represent drilled core lengths. The true width of reported mineralization is unknown at this time.Table 4: THN19-161 – 163 Collar InformationChivas Zone Drilling SummaryThe 2019 drilling at the Chivas Zone consisted of a total of 4,018m within six holes over an area of approximately nine hectares. The depths of the holes varied from 544m to 862m. The objective of the drilling was to drill test for porphyry related mineralization, which was encountered in previous drilling in hole 149 (see News Release dated September 7, 2017) and corroborated with multi-kilometre surface geochemistry anomaly and geological field mapping. The drilling campaign successfully intersected porphyry related copper-molybdenum-silver-(±gold) mineralization. Mineralization is associated with chalcopyrite, pyrite and molybdenite and occurs as disseminated or porphyry style veins. A table of highlights of the analytical results is shown below (Table 5).Click here for Figure 8. Chivas Zone Drill Location Plan MapVP of Exploration for Brixton Metals, Mr. Sorin Posescu stated, “While the Chivas Zone is a legitimate porphyry discovery that exhibits a very large surface Cu-Au-Mo geochemical footprint, this year’s drilling results have returned lower grades than anticipated. As a result, we are planning to further digest and interpret the 2019 Chivas analytical data over the winter months. We will also be assessing other areas on the property that present high potential for a porphyry discovery.”Table 5.

The Company conducted screen metallic assays on select samples from hole 159 which returned higher gold grades (see Table 8 below). The analytical results from hole 160 reported below confirms the robustness of the gold system at the Outlaw zone where drilling continues to deliver gold mineralization over significant widths and remains open in several directions.Table 7.

Composite Screen Metallics vs Original Assays for THN19-159All reported assays are uncut weighted averages and represent drilled core lengths. The true width of reported mineralization is unknown at this time.Table 9: THN19-160 Collar InformationThe Outlaw Zone represents a multi-kilometre long intrusion-related sediment-hosted gold-silver target. Mineralization is hosted within multiple horizons of sub-horizontal sediments (or siliclastics) as interbedded siltstone-graywacke with both stratigraphic and structural controls. Mineralization is also hosted in granodiorite and rhyodacite units. Early exploration work on the Outlaw Zone conducted by Chevron’s Mineral Division in the 1980’s entailed soil and rock geochemical surveys, trenching and a series of drill holes. Follow-up geological mapping and further geochemical work was conducted by Rimfire Minerals from 2000-2004. Brixton conducted further detailed soil-rock geochemical surveys and drilled a series of core holes at broad centres for about 450m of continuous strike on the west side of the gold-in-soil anomaly. Previous drilling by Brixton at the Outlaw Zone intersected 59.65m of 1.15 g/t Au, 5.64 g/t Ag from 76m depth in drill hole THN14-128 and 52.00m of 0.94 g/t Au, 5.95 g/t Ag from 78m depth and a second interval of 18m of 1.61 g/t Au, 12.31 g/t Ag from surface in drill hole THN16-132. During 2018, Brixton collected rock grab samples from the west end of the Outlaw gold-in-soil anomaly returning up to 39.4 g/t Au.Click here for Figure 9.
