Metallis Resources Inc announced the second set of assay results from the Company's 2019 drilling program. The Program has now expanded the Cliff porphyry copper-gold system northward for a strike length of 3km along the 7.5km Hawilson Monzonite Porphyry Complex at its 100%-owned Kirkham Property. The Kirkham Property is located within the prolific Eskay Camp of the Golden Triangle, northwestern British Columbia. The Program was designed to establish the continuity and controls on mineralization in some of the untested areas with more challenging topography and access. The drilling assays have confirmed large areas of near surface gold-rich mineralization along structural pathways, a unique setting which could yield greatly improved mine economics of the system.


KH19-27, drilled 1.2km to the north of Cliff, has now confirmed a 3km long porphyry system of near surface bulk-tonnage style copper-gold mineralization between the Cliff and Miles zones

Gold-rich mineralization in KH19-27 correlates with massive sulphide veins along syn-mineral conjugate faults and breccias identified as future exploration targets

Interpretation of the updated 3D geological modelling has revealed two sub-parallel zones of copper-gold mineralization striking N15°E and dips ~70° to the east leaving a substantial gap of untested area open laterally and vertically

Metallis' technical team has identified a structural control of mineralization. The hanging wall and footwall of the northeast oriented fault host two sub-parallel zones correlated with potassically altered Monzonite porphyry intrusions. An important development in the geological understanding is that the intensity of alteration, veins and chalcopyrite-pyrite ratios increases with depth. This pattern combined with 3D distribution of copper-gold grades vector towards a high-temperature, well-mineralized potassic core to be drill tested at lower elevations.

The Cliff Porphyry System shares similar geological characteristics, metallogeny and copper-gold grades with that of the nearby Kerr Deposit of Seabridge Gold's KSM project. The fault bounded porphyry dikes, hydrothermal breccias, alteration patterns and copper-gold grades are all shallow features which reflect the tip of a large porphyry system preserved at depth. The distribution of near surface mineralization represents an ideal open-pit extraction scenario during an initial development stage.
