METALLICA METALS INTERSECTS HIGH GRADE GOLD MINERALIZATION IN FIRST DRILL HOLES COMPLETED ON STARR GOLD-SILVER PROJECT

Metallica Metals Corp. has released assay results from the first three diamond drill holes (STR21-001 to 003) completed to validate high-grade gold mineralization at the Starr gold-silver project in the Thunder Bay mining district of Ontario, Canada. The project, which the company has the right to earn up to a 100-per-cent interest from Benton Resources Inc., covers a large land position (5,991 hectares) that includes several high-grade gold and silver occurrences within a 20-kilometre-long segment of the southwestern section of the Shebandowan greenstone belt.

Highlights:

  • Recent drilling has confirmed grade continuity between historical drill holes in the Starr Central target area and results indicate high-grade gold mineralization extends along strike.
  • Several thick high-grade gold zones were identified. Significant intercepts include:
    • STR21-001 -- 34.9 metres at 1.11 grams per tonne gold from 0.5 m depth including 2.1 m at 11.63 g/t Au and 1.15 m at 2.45 g/t Au and 2.45 m at 2.81 g/t Au;
    • STR21-002 -- 2.05 m at 0.82 g/t Au from 65.85 m depth including 0.5 m at 2.91 g/t Au;
    • STR21-003 -- 25.75 m at 1.14 g/t Au from 5.8 m depth including 4.45 m at 1.95 g/t Au and 0.9 m at 13.1 g/t Au and 3.3 m at 1.69 g/t Au.
  • The Starr project has historically been underexplored and drilling is expected to increase the company's confidence in the geology and structure of these mineralized zones especially in the eastern and southern parts of the project.
  • Additional assay results are expected soon with over 13 holes already completed at Starr. A second drilling rig from Forage Fusion Drilling (FFD) of Hawkesbury, Ont., has also arrived on site to complete drilling targets on the eastern side of the project.

Paul Teniere, chief executive officer and director of Metallica Metals, commented: "These first drill hole results for the Starr project have confirmed the continuity and thickness of the high-grade gold mineralization present in the Starr Central target area and at shallow depths. We are also seeing good correlation with the historical drilling results, and this is encouraging as we continue to advance our 4,000 m drilling program and continue drilling in the Starr and Powell zones. A second diamond rig has arrived at the property and has commenced drilling targets to the east that have never been tested below surface, such as the CK showing, which contains up to 16.5 g/t Au and 349 g/t Ag from historical grab samples."

Please note

The adjacent Moss Lake gold deposit hosts an indicated mineral resource of 39,797,000 tonnes grading 1.1 g/t Au for 1,377,300 contained ounces of gold and an inferred mineral resource of 50,364,000 tonnes grading 1.1 g/t Au for 1,751,600 contained ounces of gold, and is currently under care and maintenance (source: National Instrument 43-101 technical report and PEA for the Moss Lake project with an effective date of May 31, 2013, and filed on SEDAR under Moss Lake Gold Mines Ltd., now Wesdome Gold Mines Ltd.). Readers are cautioned that mineralization and mineral resource estimates on adjacent and/or nearby properties are not necessarily indicative of mineralization on the Starr project.

Metallica Metals has focused its diamond drilling program on a combination of historical high-grade gold mineral occurrences within the Starr project. The three main areas to be tested are the Central (Starr and Powell zones), Eastern (CK showing plus additional targets) and Western (West and South showings) Starr target areas. Drilling is testing several structural and geophysical targets determined from the company's recently completed airborne mag-EM (electromagnetic) survey, in combination with all historical geochemical, geophysical and geological data from the project. Drilling supervision and core logging and sampling are being managed by Fladgate Exploration Consulting Corp. of Thunder Bay and diamond drilling is being completed by Missinaibi Drilling Services Ltd. of Timmins and Forage Fusion Drilling (FFD) of Hawkesbury, Ont. All diamond drill core is NQ-size diameter and all holes are being surveyed using a downhole Reflex survey tool.

Drilling around the central portion of the property (Starr Central) has been focused on the Starr showing and Powell zone. The company has used available historical data, recommendations from previous work reports, as well as targets from a newly completed geophysical and structural interpretation to plan drill holes in this area. Several drill holes will act as infill, testing the continuity between known values, while others will test structures that have never been drill tested that also hold gold values at surface.

Hole STR21-001

Hole STR21-001 was drilled halfway between historical drill holes SAG-06-11 and 91-3. The purpose of this drill hole was to confirm the continuity of grade between the two historical holes. A summary of the significant mineralized intervals include:

0.5 to 5.9 m: mafic intrusive rock

Intrusive rock selectively has crosscutting planar and curvilinear quartz veining associated with the mineralization of localized pyrite clusters. Host rock is very magnetic, with flaky and metallic mineral found in veins from 0.9 to 1.35 m most likely hematite. Lithology is altered with hematite occurring primarily in sections three to 5.9 m. Area of albite alteration from 1.65 to 2.4 m. Bottom contact is measured at 75 degrees to core axis:

  • 0.9 to 1.35 m (veining): intense alteration and sulphidization associated with this quartz vein, curvilinear quartz vein surrounded by planar veinlets;
  • 1.35 to 2.4 m (veining): crosscutting planar quartz veins, heavily haloed in alteration of ab and hem.

5.9 to 20.9 m: mafic volcanic unit

Area heavily chloritized with green colour from 5.9 to 15.2.2 m. Area of intense crosscutting with white/barren quartz veins occurring from 10 to 15 m. Albite alteration present from 15.3 to 16.7 m. Bottom contact is calculated at 70 degrees measured to core axis.

20.9 to 23.35 m: granitic intrusive rock

Distinct unit of coarse-grained intrusive rock, heavily altered with albite, K-feldspar and silica, 3 per cent pyrite and pyrrhotite associated with intruding quartz veins. Quartz veins take a brecciated-style alongside tourmaline. Bottom contact is calculated at 70 degrees measured to core axis.

23.35 to 25.65 m: felsic to intermediate intrusive rock

Gradational contact with unit above. Zone includes crosscutting planar veins with halos of alteration. Pyrite and pyrrhotite associated with quartz veins. Bottom contact is calculated at 80 degrees measured to core axis.

25.65 to 27.35 m: mafic volcanic unit

Less chloritized mafic volcanic with black colour including multiple barren/white quartz cutting veins along foliation of 60 degrees. Bottom contact is calculated at 60 degrees measured to core axis.

Hole STR21-002

Drill hole STR21-002 was planned to test the geology and mineralization between historical drill holes SAG06-11 and SR-97-12. Geological logs indicate assays in the hangingwall are more continuous. A summary of the significant mineralized intervals includes:

63.15 to 68.7 m: ultramafic

Lithology is extensively altered with quartz-carbonate veins and selective zones of pyrite up to 2 per cent (65.6 to 66.35 m). Heavily sheared quartz veinlet/zone with 2 per cent pyrite from 67.1 to 67.45 m. Large quartz-carbonate veinlets running along core axis from 63.15 to 63.95 m. The bottom contact angle with the diabase dike below measures 70 degrees.

Hole STR21-003

Drill hole STR21-003 was planned as a stepout of historical drill hole SR-97-12 to confirm continuity of grade along strike to the northeast. A summary of the significant mineralized intervals includes:

27.8 to 46.5 m: moderately silicified-chloritized dark igneous rock with large grains of feldspar and quartz eyes occurring throughout

The feldspars have been strongly altered by chlorite and epidote leaving them with a light green appearance. Light blue-white carbonate veinlets occur sporadically throughout. Little to no mineralization present in this unit. Toward the lower part of the unit the feldspars almost completely disappear (37 to 46.51 m) and the unit takes on more of an intermediate composition with small quartz eyes still present.

46.5 to 49.5 m: moderately silicified-chloritized volcanic rock with about one-centimetre-wide quartz-carbonate veinlets occurring throughout in chaotic orientations

The veinlets are often associated with moderate hematite alteration, and some are composed dominantly of a pink carbonate. The strong pyritization and alteration associated with veining observed in this unit at the top of the hole have completely disappeared at this point. From 46.51 to 64.12 m this volcanic unit is frequently crosscut by a porphyritic hematite altered dike. Varying amounts of pyrite dissemination throughout the unit ranging from trace to 3 per cent.

49.5 to 50.1 m: heavily hematite-altered porphyritic dike with a fine-grained dioritic ground mass

The ground mass also has weak calcite alteration. Mineralization is composed of 0.5 per cent pyrite and is disseminated throughout. The upper contact of the dike is sharp and nearly perpendicular to core axis. The lower contact is shallow, undulating and nearly parallel to core axis.

50.1 to 57.2 m: weakly silicified and chloritized massive volcanic rock with chaotic quartz-carbonate veinlets occurring throughout.

57.2 to 59.25 m: section of strongly silicified alternating units of mafic metavolcanics and porphyritic dike, with the dike being the dominating unit (about 75 per cent)

Pyrite mineralization is disseminated throughout both units at about 1 per cent. The dike has large feldspar phenocrysts (maximum one cm in width) that have a pinkish alteration. The ground mass of the dike is moderately calcite altered.

59.25 to 63.1 m: massive, moderately silicified and calcite altered wall rock with frequent occurrences of calcite, chlorite+epidote, and k-spar (hard salmon pink mineral) filled fractures

The carbonate alteration is stronger in some sections, effervescing quite strongly. Mineralization consists of about 1 per cent disseminated pyrite.

63.1 to 64.1 m: chlorite-calcite altered mafic volcanic dike with large well-developed feldspar crystals and sporadic calcite veinlets (one to two cm wide) throughout

The composition of this dike is very similar to the hosting mafic metavolcanic; however, the contacts between them are sharp. Mineralization consists of disseminated pyrite throughout (about 1 per cent) with an increase near the upper and lower contacts (about 4 per cent).

64.1 to 73.7 m: strongly chlorite altered and moderately silicified mafic volcanic with pinkish calcite veinlets crosscutting the host rock

Strong interstitial calcite alteration occurs from 64.12 to 66.14 m. Trace pyrite mineralization disseminated throughout, with a slight preference along fracture surfaces.

Analytical and quality assurance/quality control procedures

Metallica Metals and its geological consultants (Fladgate) have implemented a robust quality assurance and quality control (QA/QC) program for the Starr project that complies with CIM (Canadian Institute of Mining, Metallurgy and Petroleum) exploration best practices for sampling, chain of custody procedures and analytical methods. Certified gold reference standards, blank material and duplicates are routinely inserted by the site geologists at the on-site core processing facility as part of the QA/QC program in addition to the control samples inserted by the laboratory. The NQ-sized half core samples are labelled and sealed in plastic sample bags and held on site in a secure location until transported by truck to Activation Laboratories in Thunder Bay, Ont., where they are prepared and analyzed. ActLabs is independent of Metallica Metals.

ActLabs' QA/QC system is registered to international quality standards through the International Organization for Standardization/International Electrotechnical Commission 17025:2017 (including ISO 9001:2015 and ISO 9002 specifications) and is accredited to the Standards Council of Canada (SCC) Requirements and Guidance for the Accreditation of Testing Laboratories, specific to mineral, forensic and environmental testing laboratories.

Core samples are analyzed for gold using fire assay-AA (atomic absorption) techniques (1A2-Au-30). Samples returning over five g/t gold are analyzed using fire assay-gravimetric methods (1A3-Au-30). Selected samples are also analyzed with aqua regia partial digestion methods for ICP-MS (inductively coupled plasma mass spectrometry) (ultratrace 1-15). The company and its geological consultants confirm all assay results reported herein have passed QA/QC protocols.
