METALLIS INTERSECTS SIGNIFICANT, NEAR SURFACE, PORPHYRY COPPER/GOLD MINERALIZATION AT THE CLIFF ZONE ON THE KIRKHAM PROPERTY
January 17, 2020
Vancouver, BC: Metallis Resources Inc. (TSX-V: MTS; OTCQB: MTLFF) (the “Company” or “Metallis”) is pleased to announce the first set of assay results from the Company’s 2019 drilling campaign (the “Program”) which targeted the Cliff Zone of the 7.5km Hawilson Monzonite. The 100%-owned Kirkham Property (the “Property”) is in the prolific Eskay Camp of the Golden Triangle, northwestern British Columbia.
The Program was designed to better understand the controls on mineralization and infilling some substantial gaps in the geologic model. Building on the success of the 2018 drilling campaign at the Cliff Zone, the exploration team has successfully confirmed and extended shallow bulk-tonnage-style copper/gold mineralization. Rarely, does this advantageous configuration exist in B.C. which could yield greatly improved mine economics.
2019 Drilling Highlights – Cliff Zone
- The 2019 drilling assays combined with previous results have confirmed a 1,800m-long zone of near surface gold-rich mineralization (Click here to view map).
- Extensive intervals of gold-rich mineralization such as 126m of 0.52 g/t AuEq in KH19-30 are associated with potassic altered Monzodiorite porphyry intrusions, to be targeted at deeper levels.
- Higher grade gold intercepts, as in KH19-28, correlates with intense silicification and massive sulphide veins along syn-mineral tensional faults, identified as future exploration targets
The 2019 drill program at the Cliff Zone comprised three deep holes totaling 1,464 meters. These drill holes formed part of a larger comprehensive 11-hole (4,460m) drilling program designed to evaluate the porphyry copper/gold and epithermal gold targets throughout the 7.5 kilometer-long Hawilson Monzonite Intrusive Complex. Results from the other eight holes will be released upon further assaying, verification and data analysis.
All three holes intersected significant mineralization, highlighted by KH19-30, which returned 126.5m @ 0.52 g/t gold equivalent* associated with the core potassic altered porphyry. Higher grade gold intercepts, as in KH19-28, correlates with intense silicification and massive sulphide veins along syn-mineral tensional faults, identified as future exploration targets (Click here to view long section). The intensity of alteration, veins and chalcopyrite-pyrite ratios increases with depth. This pattern vectors towards a deeper, high temperature potassic core to be tested in future exploration programs. The 2019 results, together with previous results, are tabulated below.

The Cliff results demonstrate the continuity of Cu-Au Porphyry mineralization for at least 1.8km. The mineralization remains open in most directions, with potential along strike to the north. Two mineralized holes drilled by a previous operator, extend the Cliff Zone a further 500m to the north. Of significance is the tabular distribution of mineralization down the topographic slope representing an ideal open-pit extraction scenario.
The geological characteristics, metallogeny and copper-gold grades of the Cliff porphyry system are like several porphyry copper-gold deposits in British Columbia, including the Kerr Deposit of Seabridge Gold’s KSM project.
Metallis Resources’ Vice President of Exploration, David Dupre stated
This season’s drilling has been very successful. We have shown that the copper-gold mineralization occurs close to the surface slope and have linked these zones with copper-gold mineralization intersected in previous drilling.
Mr. Dupre added,
We are excited about these results and plan to further define the higher grade mineralization as well as test the northern continuation of the Cliff Zone.
Metallis’ Chief Geologist, Dr. Razique added,
The structural traps with focused fluid flow along syn-mineral tensional faults host some of the unusually high-grade gold mineralization in the Cliff zone, this will be targeted in future exploration programs.
Dr. Eric Grunsky has been engaged to carry out a geostatistical study which utilizes porphyry vectoring and fertility tools (“PVFTs”). These use the chemical compositions of hydrothermal alteration zones to predict the likely direction and distance to mineralized centers. Our existing hyperspectral surveys will augment this work – particularly, to discover higher grade, core zones which can be masked by distal propylitic blankets.
In 2020, Metallis plans to expand the known higher-grade zones at Cliff and to evaluate targets generated by our PVFT studies.
Metallis Resources has implemented a rigorous quality assurance / quality control (QA/QC) program to ensure best practices in sampling and analysis of diamond drill core. All assays are performed by ALS Canada Ltd., with sample preparation carried out at the ALS facility in Terrace, BC, and assays at the North Vancouver laboratory. Assay values are uncut. For gold, fire assays are performed as per ALS method Au-AA26 (0.01- 10.00 g/t Au) using 50 grams of sample measured by atomic absorption (AA). Assays equal to or greater than 10 g/t Au are reanalyzed gravimetrically by method Au-GRA22. Silver and copper are analyzed by ALS method ME-MS61 with a 4-acid digestion followed by ICP-MS analysis.
David G. Dupre, P.Geo., Vice President, Exploration for Metallis Resources Inc. and a Qualified Person as defined by NI 43-101, has reviewed and approved the technical information in this press release.
