Looking West – Hazelton Interbedded sediments and Rhyolite units with intense hematitic gossan. 

Geology & Exploration Potential



Rhyolite Ridge, located ~1 km to the west of the Cole porphyry, was discovered during a mapping and prospecting program in October 2018. The field traverses outlined widespread 200 x 300m sericitic alteration and intense gossan constrained within a north-south trending graben structure in the western part of Kirkham Property. The Rhyolite Ridge target is represented by massive felsic volcanics (Rhyolite) interlayered with a sequence of clastic sedimentary rocks belonging to the Hazelton group. The interbedded felsic volcanic and argillite-siltstone units show intense sericitic and white argillic alteration, hematitic gossan and local massive pyrite bands; an alteration assemblage also visible in the Worldview 3 satellite images (see below).

Rhyolite Ridge is an early stage prospect, where only 12 selective rock samples were collected in 2018 and analyzed by the 4-acid digestion ICP-MS method. One of the samples (Y060657), collected from a limestone unit with quartz-carbonate veins, returned 0.5 g/t Au, which highlight the potential of a vent proximal facies with a siliceous, shallow marine exhalative unit, comparable to the Eskay Creek host stratigraphy. The Metallis technical team is currently evaluating the structural setting, lithostratigraphic units and geochemical results to vector higher grade VMS mineralization and a potential volcanic vent in the area. The 2019 exploration program includes detailed mapping, selective rock-chip and channel sampling and interpretation of the VTEM conductors and worldview 3 spectral analysis to generate drill targets.

Geology & Exploration Potential



The Natt showings, located ~500m to the south of King target, is historically described as narrow N-S trending “Chert bed” interpreted as part of a rift-fill segment of the Eskay Rift that hosts limestone and exhalative rocks. The local stratigraphy shows a succession of volcanic flows, coarse pyroclastic rocks, mudstones, and minor limestone (Chert beds) of the Hazelton formation targeted for VMS style mineralization.

During the 2018 exploration program, the high-resolution VTEM, Worldview 3 remote sensing and mapping of the Hawilson Monzonite porphyry to the east evolved a new perspective of the Natt target. The subtle magnetic response from VTEM surveys, anomalous gold values in soil and rock samples are being interpreted for a shear vein gold or an epithermal gold system to the west of Hawilson Monzonite porphyry complex. The 2019 field work will include detailed geological mapping and rock-chip sampling, designed to integrate the VTEM conductors with local stratigraphy and refine the mineral deposit model and generate drill targets.

Looking North – felsic dikes and quartz veins cutting across pyritic shale to the north of Fewright Creek 

Exploration Highlights



The Fewright Creek prospect is situated on the south-western margin of Hawilson monzonite, immediately to the west of Cliff zone. It is represented by an arcuate resistivity and magnetic anomaly surrounding a magnetic low. The widespread hematitic gossan and broad hook shaped VTEM resistivity anomaly correlates with the Stuhini shale-graphite and arkosic clastic sedimentary rocks with disseminated and banded pyrite and pyrrhotite. The geophysical results indicate that this anomaly expands in size with depth.

Metallis’ technical team in 2018 investigated the Fewright Creek VTEM anomalies and the source of the historic placer gold showings and geochemical anomalies. Prospecting downslope from the VTEM anomaly, Metallis geologists identified several boulders showing intense silicification and epithermal style mineralization of chalcopyrite, sphalerite and galena grading 0.5% Cu and 0.77% Zn. Traversing further to the north, the mineralized monzodiorite boulders along the creek indicate the presence of a porphyry center nearby. Follow up work for 2019 will involve soil sampling as well as mapping and rock-chip sampling in the upper portions of the prospect.

Looking NE – Dike Swarm Target area along the Mount Dunn Plateau 

Geology & Exploration Potential



The dike swarm target is located immediately to the north of Fewright Creek and ~2 km west of the Hawilson Monzonite. This target is highlighted by a north-trended corridor of 0.5 to 3 m thick granodiorite to andesite feldspar-phyric dikes, which makes up 30-40% of the rock volume. This corridor is about a kilometer wide and extends across the broad alpine terrain to the west of Mt Dunn. The north-south trend and structural setting of the dikes suggest a correlation to Hawilson Monzonite to be investigated in future exploration programs. A large sericite anomaly has also been discovered just east of the dike swarm using the world view 3 satellite imagery. Sericite is an alteration mineral associated with Au-Cu porphyritic intrusions and it can be used to vector porphyry centers. During the 2019 field program, detailed geological mapping would be essential to understand the structural fabric, anomalous gold values, sericitic alteration and significance of the dike swarm, allowing the Metallis geology team to generate drill targets in this area.

Visual Reconnaissance by helicopter identified patchy gossans along Harrymel Creek in Iliad target. 

Geology & Exploration Potential



The Iliad target lies along the eastern edge of Harrymel Creek in the eastern part of the Kirkham property. Although the Iliad target is completely covered by vegetation, some of the clearings along creeks display fault-controlled gossans to be investigated. The 2018 mapping and prospecting work at the Iliad target revealed a massive diorite stock emplaced into Triassic Stuhini sediments. The diorite stock is characterized by coarse grained textures with quartz-sericite-pyrite and chlorite alteration assemblages. A soil line traverse was conducted which resulted in one sample being anomalous - yielding 0.46 ppm gold.
Later in the 2018 field season, VTEM was flown over the eastern edge of the property and revealed a distinctive sub-circular magnetic anomaly surrounded by magnetic low. The gossans observed during visual reconnaissance from the helicopter correlate with the magnetic lows (magnetite destructive) and a distinct conductive anomaly near the Harrymel creek. Two of the historic Minfile reports (104B226, 104B230) in the area also reported copper and zinc showings and warrant detail mapping, prospecting and sampling to determine the nature of the gossan coincident with the resistivity and concentric zonation of magnetic high-low signature at the Iliad target.

Looking N: Sericitic alteration (below) and Rhyolite units (above) within Hazelton rocks N of Terwilligen Creek. 

Geology & Exploration Potential



The Terwilligen Target is the northward continuation of lithostratigraphic units and Hawilson Monzonite in the Cole targets. During the 2018 exploration program, Metallis geologists marked the Triassic – Jurassic unconformity “Red Line” and outlined a 100 x 50m wide zone of sericitic alteration and narrow monzodiorite dikes immediately to the north of Cole porphyry system. Further to the north, extensive, fault bounded felsic volcanics (Rhyolite) are overlain by clastic sedimentary rocks belonging to the Hazelton group. Metallis is planning an aggressive fieldwork program for 2019 to map the apparent horse and graben structure and associated gossans for potential VMS mineralization in the area.

A large sub-circular circular VTEM resistivity anomaly coincident with a cluster of magnetic anomalies along the eastern portion of Kirkham property highlight the N-S trending faults along the western margin of Eskay Rift. This area is relatively underexplored and warrants detail geological mapping, sampling and follow-up of the VTEM anomalies to expand on the current understanding and potential of porphyry and/or magmatic Ni-Cu mineralization in the area.

Geology & Exploration Potential



The Maximillian target lies at the southern end of Metallis’ Kirkham Property and approximately 1 km to the south of the historic Max Iron deposit (Minfile No. 104B 013). The area is underlain by a large NE trending Jurassic quartz-diorite stock intruded into the upper Triassic Stuhini volcanics and sedimentary rocks. The Max Iron deposit is characterized by high-grade, magnetite bearing skarn with elevated copper and cobalt values that was discovered and drilled in the 1960’s. Historic contour soil lines were completed across the Maximillian target and were found to have multiple samples greater >100 ppb gold as well as elevated copper and molybdenum values.

An interpretation of the historic geochem and VTEM magnetic and resistivity anomalies suggest that the Maximillian area is prospective for porphyry-skarn mineralization. Any younger mafic intrusive phase (gabbros) will highlight the potential of magmatic sulphide mineralization. Metallis plans to carry out geological mapping and soil sampling along the clustered VTEM magnetic and conductive anomalies to evaluate and generate drill targets.

Geology & Exploration Potential



The King target displays distinct VTEM and geochemical anomalies at lower elevations on the vegetated slopes above King Creek. The VTEM survey completed by Metallis in 2013 indicated a strong, coincident low-resistivity and magnetic anomaly within the Triassic Stuhini rocks. In 2017 the geophysical anomaly was tested with a single diamond drill hole (KH-17-10), which intersected 38.4m of intermediate agglomerate before passing into clastic sediments which continued to the bottom of the hole at 355m. The drill core logs and assays suggest that the VTEM anomaly is attributed to graphitic shale, patchy and veinlet pyrite-pyrrhotite mineralization which partly explained the VTEM anomaly. The distinctive oval resistivity and magnetic anomaly could be related to deformed pyrrhotite-bearing sediments. However, local cm-scale intercepts of stratabound sulphides and anomalous lead, zinc, silver, antimony, arsenic and mercury are interpreted to be a distal expression of a VMS system to be investigated.

VTEM Resistivity (Tausf) anomaly at the King Target 

A strong gold geochemical anomaly to the east of King target was discovered by Cominco Ltd. In 1988. Soil contour lines were completed at lower elevations and revealed a 200m-wide gold soil anomaly to the south of King Creek near the Adam fault. The anomalous gold was found to be hosted in decimeter scale pyritic lenses hosted in black shales.

The gold geochemistry is highlighted by a soil sample with 10.9 g/t Au and selective rock samples containing greater than 3 g/t Au including one sample of 9.5 g/t Au. (Westcott, 1988) The geochemical gold signatures (Cominco, 1988) have had minimal follow up by Metallis, an example of the untested potential on the Kirkham Property. The 2019 field program will involve sampling and mapping of the geochemical anomaly to confirm historic results as well as interpret the style of mineralization found at this location.
