Overview




Claims size: 10,600 Ha (30 contiguous claims)

Ownership: 100% owned by Metallis Resources

Acquisition: Metallis purchased the group of claims assembled by Dr. Rodney Kirkham in July 2013.

Geology: The Kirkham property lies within the Stikine Terrane, near the boundary between the Intermontane and Coast Tectonic Belts of the Canadian Cordillera. It is underlain by volcanic and sedimentary rocks of the Upper Triassic Stuhini Group and the Lower to Middle Jurassic Hazelton Group. According to Kyba and Nelson (2016), the contact between these two rock formations is a key geological marker for copper-gold mineralization in the Golden Triangle. Also referred to as the “Red Line”, this marker has been traced over a strike length of 10km (north-south) on the Kirkham Property.

Location & Access



The Kirkham Property is located 65 km northwest of Stewart in northwestern British Columbia and is centred at 56 ̊29’ N latitude and 130 ̊40' W longitude, within the Liard and Skeena Mining Divisions. Situated within the Golden Triangle, the Property is proximate to several mines and advanced exploration projects, including Barrick’s past-producing Eskay Creek Mine (12km southwest), Pretium Resources’ Brucejack deposit (40 km southeast) and Seabridge’s KSM and Iron Cap deposits (30km). The closest road access is at the g Eskay Creek, connected by 60 km of controlled-access gravel road to Highway 37, located a couple of kilometres south of the Bob Quinn Lake airstrip. In recent years, a number of infrastructure improvements have been made in the region, inlcding the paving of Highway 37, the opening of ocean port facilities for export of concentrate at Stewart and the completion of the Northwest Transmission Line, which provides cheap power for mineral production purposes. The Kirkham Property is accessible by helicopter. The nearest helicopter base is at Stewart, although helicopters are commonly stationed from Bob Quinn Lake and nearby exploration projects.

Historical Work



The Unuk River area has attracted prospectors, geologists and entrepreneurs in search of mineral deposits since 1893 (Grove, 1986). The earliest reported work around Kirkham property was in 1929, when “two claims [were] located, carrying free gold on the surface to the amount of $10 to the ton” (17 g/tonne) on Glacier (Fewright) Creek (BCDM Annual Report, 1929, p. C112). Exploration of the area has been concentrated in a few waves including

  1. Initial exploration of accessible areas in the 1920s and 1930s, on foot or float planes out of Stewart.
  2. Helicopter gossan reconnaissance in the 1950s and 1960s.
  3. Porphyry copper exploration in the 1970s.
  4. Gold exploration in the early 1980s and opening of Snip and Eskay Creek mines in the early 1990s.

Significant Exploration Work and Results

  • Airborne magnetic survey in 1959 led to delineation of the Max iron (-copper-cobalt) deposit with an historic, non-compliant resource of 11.2 million tonnes grading 45% Fe (Minfile, 2013)
  • Great Plains Development Company in 1975 and 1976, collected soil and rock chip samples between King and Fewright Creeks. The sampling defined a semi-continuous 200-300 m wide Cu-Mo soil anomaly (>180 ppm Cu, >7 ppm Mo) and 2 rock chip samples yielded 0.60% Cu and 1.28 g/t Au. The reconnaissance silt and soil samples were followed up with a soil/VLF/magnetics grid over the Cole prospect on the ridge-top between King and Terwilligen Creeks.
  • Du Pont’s geochemical sampling 1981 showed a 100 x 600 m north-south Cu-Au soil anomaly (>250 ppm Cu, >100 ppb Au) which was then extended further 700 m to the south and remained open to the north and south. Although a massive pyrite boulder was discovered in the Gossan Creek, which returned 7.1 g/t Au, but no significant mineralization reported in the outcrops (Korenic, 1982).
  • Placer/Skyline’s in 1983 work on the Cole prospect revealed elevated Au, Ag, As, Zn in isolated soils 500 m west of Cole Lake (Gareau, 1983).
  • Cominco in 1988 reported massive pyrite lenses along the gossan creek (Adam Fault) that returned up to 9.5 g/t Au and veinlets within argillaceous siltstone in the vicinity of the fault (Westcott, 1988). Winslow Gold Corp., in late 1988 commissioned an airborne geophysical survey which extended north as far as King Creek and covered the Mt. Dunn prospect (Dvorak, 1989b). Mapping, prospecting and geochemical sampling in following year identified altered and mineralized “quartz diorite” (monzonite) south almost to Fewright Creek (Aussant and Dupre, 1989c).
  • Corptech Industries Inc. in 1989 carried out a helicopter-borne VLF/magnetic survey over King and Consoat claims. They confirmed the Great Plains’ Cu-Mo soil geochemical anomaly and revealed a coincident, but slightly narrower, >100 ppb Au soil anomaly. Limited IP lines across the Evan and Cole prospects indicated two zones of high chargeability (>20 ms) near the eastern and western limits of the lines. Corptech drilled three test holes (364 m) and intersected pyritic and silicified monzonite carrying average 604 ppb Au over 14.5 m (Chapman and Dewonck, 1989; Chapman et al., 1989; Chapman et al., 1990).
  • The exploration work from 1991-1991 by Canadian Industrial Minerals Corp. in the Achilles area (King East) identified four gold-in-soil anomalies with up to 3.3 g/t Au (Wesa,1990a). The trench samples to the north of King Creek returned 0.40 m @ 17.1 g/t Au and 6.0 m @ 2.0 g/t Au (source unknown) whereas soil sampling south of King Creek identified a new 5.9 g/t Au soil anomaly (Howson, 1991a).
  • Rimfire Minerals in 2002 and carried out limited fieldwork on the Mt. Dunn and Cole prospects (Awmack, 2003).
  • In 2006, Paget Minerals Corp. carried out extensive rock sampling (Marsden, 2007) and drilled five holes (1,587m) with their best intersection of 332 m @ 0.13% Cu and 0.18 g/t Au (Bradford, 2009).
  • Metallis Resources Inc. in 2013 acquired the Mt.Dunn, Achilles and other claims and consolidated the land package and named as Kirkham Property. Based on the technical appraisal of the exploration targets, Metallis conducted an extensive airborne VTEM survey covering the eastern Kirkham (Awmack 2013) and western Kirkham property (Dupre D., 2016).

Periodic exploration work from 1960 to 2018, by various operators is summarized in the following table.

Summary of Historic Exploration on the Kirkham Property

Recent Work (2013 - 2018)



2013

Metallis Resources acquired the Kirkham property originally assembled by Dr. Rodney Kirkham (a world-renowned copper-gold expert). A 50 km2 airborne EM/Mag/Radiometric survey outlined a number of potential targets in the eastern claims. Metallis Resources expanded the property by the acquisition of all other claims situated inside Kirkham Property.

2014

Metallis expanded the Kirkham property with the acquisition of Achilles and King Creek claims where a heavy mineral sample returned 3.8g/t Au. In August 2014, Metallis commenced an exploration program focused on the “King Anomaly” and carried out regional mapping, sampling and trenching.

2015

Metallis conducted geological mapping and sampling over the southernmost part of Hawilson Monzonite in the Stikine Terrane. This intrusion belongs to the Texas Creek plutonic suite responsible for most porphyry copper-gold deposits in the Golden Triangle including the KSM cluster with an endowment of >100 million ounces of gold; located ~20km to the east of Kirkham property. Evaluation of the Homer prospect and soil geochemistry program produced elevated Au including two samples returned 0.2 and 0.4 g/t Au respectively. A gossanous outcrop of chloritized and pyritic andesite returned 1.48 g/t Au and 3.1 ppm Ag.

2016

Metallis Resources engaged Geotech Ltd to conduct a VTEM/magnetic/radiometric survey over a 6000 hectare portion of the property, which was not surveyed in 2013. The results were interpreted to identify conductors related to veins and massive sulphide lenses (0-400m) as well as delineate structures and potassically altered and mineralized intrusions using magnetic and radiometric signals extended down to depth of hundreds of meters below the surface.

  • Fewright Creek represents an arcuate resistivity and magnetic anomaly surrounding a mag-low that coincides with phyllic alteration, gossan, and a small felsic plug reflecting a porphyry Cu-Au system.
  • King East target comprises large coincident magnetic and resistivity anomalies. Numerous gold-bearing veins and several small felsic stocks have been mapped on the southern part of this target.
  • North and South Terwilligen represent coincident magnetic and resistivity anomalies. The propylitic alteration minerals supported by geophysical modelling indicated a high level porphyry system.
  • King Target is represented by a linear, very strong coincident resistivity and magnetic anomaly, outboard from the mineralized Hawilson Porphyry. This feature is similar to the geological setting of the Snip Mine, located 40-km to the northwest. The presence of a pyroclastic dome, limestone units and mineralized chert layers also could be indicative of an Eskay Creek – type VMS deposit.

2017

Metallis Resources Inc. in 2017 carried out a comprehensive exploration program focused on mineral deposit models and drilled 5 holes totaling 1648m. This program confirmed a 3-km long, north-south trending corridor of porphyry copper-gold mineralization along the southern half of the 6-km long Hawilson monzonite overprinted by a gold-rich zones of up to 3.36 g/t (KH17-08) Metallis’ technical team reviewed several other targets and identified the potential of (1) Porphyry Cu-Au systems at Camp, Cole, King E and Terwilligen prospects, (2) Magmatic Ni-Cu mineralization at Thunder North and South and (3) VMS/Shear vein Au showings at the Natt, King and Etta prospects (Razique and Weatherup 2017).

2018

Based on the results from 2017 exploration and drilling program, Metallis Resources in 2018 conducted a high resolution VTEM survey to identify conductors associated with porphyry Cu-Au, VMS-Shear vein Au and magmatic Ni-Cu mineralization throughout Kirkham Property.

CLIFF TARGET



Porphyry-Copper-Gold

The Cliff Porphyry system extended for 0.5 x 2 kms is represented by multi-phase intrusions and breccias associated with the 6-km-long Hawilson Monzonite porphyry complex. The geological setting is strikingly similar to Seabridge’s KSM deposits, located 20 km to the east of the Kirkham Property. The KSM deposits contain a proven and probable Mineral Resources of 2.2 Bt grading 0.55 g/t gold and 0.21% copper and 2.6 g/t silver.

The Hawilson Monzonite was tested in 2009 with five shallow drill holes showing an increase in copper-gold grades with depth. The drill hole MD-09-01 deeply penetrated the Monzonite porphyry and intersected 92.67m @ 0.217% Cu and 0.277 g/t Au at the bottom. Rock samples also show improving grades down section. At the lowest exposure, 22 rock samples from monzonite returned average 0.7 g/t gold and 0.35% copper. The extensive QSP alteration footprint at surface and patches of potassic alteration and veining in the drill core suggest a deeper, high-grade potassic core to be tested by Metallis’ exploration and drilling programs.

2017 Exploration and Drilling Program

  • Focused on geological and alteration mapping of the Hawilson Monzonite south of drill hole MD09-01 (92.67 m @ 0.22% Cu and 0.28g/t Au) to Fewright Creek.
  • Phase 1 confirmed that the mineralized monzonite body from hole MD09-01 to Fewright Creek, is up to 300m wide and extends ~1.5 km along strike and traced down to 500m in the drill holes and along the slopes. Historical grab samples at lower elevation have returned geochemical grades up to 1.8% Cu and 4.3 g/t Au.
  • Furthermore, the intensity of QSP alteration (Phyllic) and copper mineralization (chalcopyrite + malachite ± bornite) within the monzonite is stronger south of the drill hole MD-09-01 and is continuous to the Cliff Zone.
  • Resistivity data from the 2016 VTEM survey by Metallis outline a strong conductivity anomaly (Fewright Creek) coincides with the strongest phyllic alteration and Cu/Au mineralization from hole MD09-01 to the Cliff Zone. 

Highlights

  • Drilling at the Cliff target confirmed the continuity of Copper-Gold mineralization in the Hawilson Monzonite for at least 1.5 km along strike.
  • The first two drill holes at Cliff porphyry system intersected extension of the gold-rich zones to the south and increasing copper-gold grades with depth as highlighted below the historic drill hole MD-09-01
  • Drill core in KH-17-07 and KH-17-08 intersected mineralized and altered monzonite showing improving copper-gold grades with depth correlated with the intensity of potassic alteration.

THUNDER NORTH TARGET



Magmatic Nickel-Copper

Thunder North prospect is located immediately south of Garibaldi’s E&L (Nickel Mountain) Project on the western flank of the Eskay Rift. The project area is underlain by extensive mafic volcanic and sedimentary rocks of the Hazelton Formation that host the nickel sulphide mineralization at E&L. Following the discovery of massive Ni-Cu sulphides at E&L, Metallis Resources carried out a rapid exploration program and discovered a 100 x 150m wide diorite intrusive complex with narrow mafic intrusions (Gabbros) favourable for magmatic Ni-Cu sulphide mineralization. These intrusions appeared to be slightly differentiated with up to 7.5wt% MgO. The initial drill hole (KH17-09) collared adjacent to the gabbro tested a pyritic gossan at the margin of the gabbro hosted by andesitic volcanic and diorite rocks.

Exploration Potential

Mineral exploration in the Eskay camp demonstrates the presence of mafic intrusive magmatism in the Hazelton stratigraphy along the southern extension of the western margin of the Eskay Rift. This segment of the rift has seen no historic exploration for nickel sulphide mineralization, so the discovery of mafic intrusions is critical in future exploration programs. The flanking structures of the western margin of the Eskay Rift were likely a key control on the emplacement of small open system intrusions like the one at Nickel Mountain.

The differentiated mafic intrusions with chaotic textures and/or breccias are recognized as an important feature of nickel sulphide ore deposits. A thorough search for these types of rocks or their manifestations on geochemical and/or geophysical surveys is a critical next step in the exploration of the Kirkham Property.  The 2018 summer program consist of

  • High-Resolution VTEM survey with 83.3m line-spacing designed to test the property for conductive targets on the scale of E&L.
  • Geological mapping, rock chip, and stream-sediment sampling, structural mapping, and follow-up of conductive and/or magnetic features from the VTEM survey.
  • Discover the chaotic textured / brecciated olivine gabbros coincident with conductive VTEM anomalies leading to generate drill targets.

THUNDER SOUTH TARGET



Magmatic Nickel-Copper

Thunder South prospect is located southeast of Garibaldi’s E&L (Nickel Mountain) Project on the western flank of the Eskay Rift. The project area is underlain by extensive volcanic and sedimentary rocks of the Hazelton Formation that host the nickel sulphide mineralization at E&L. Following the discovery of massive Ni-Cu sulphides at E&L, Metallis Resources carried out a rapid exploration program and identified a linear, 300m-long, 2-10m-wide NE-trending mafic dike reflecting the potential for magmatic Ni-Cu sulphide mineralization in the area.

  • Discover the chaotic textured / brecciated olivine gabbros coincident with conductive VTEM anomalies leading to generate drill targets.

KING TARGET



Print

The King geophysical target is a planar, very strong, coincident low-resistivity and magnetic anomaly. It is situated within the Jurassic Hazelton rocks along the Red-line of Kyba (2014); the Hazelton-Stuhini contact spatially coincident with several prolific deposits including Eskay Creek, Brucejack, KSM, Red Chris, Snip and others throughout Northwest BC.

The initial drill hole KH-17-10 from 2017 drilling campaign 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 reflect that the conductive anomaly is attributed to graphitic shale with 5-8mm wide pyrrhotite bands near the volcanic/sediment contact. The stratabound sulphides and several intervals of anomalous pathfinder elements including lead, zinc, silver, antimony, arsenic and mercury are interpreted to be a distal expression of a VMS system.

Exploration Follow Up



Metallis Resources plans to carry out a vigorous program of geological mapping and geochemical sampling supported by the recent high resolution VTEM survey and plate modelling. The geometry of sulphide conductors, litho-stratigraphic units and associated geochemical anomalies are critical in the discovery of VMS and/or shear vein gold mineralization in this area.

 

KING EAST TARGET



The King East target is defined by coincident magnetic and resistivity anomalies. Previous work highlighted numerous narrow gold-bearing veins, small intrusive stocks and anomalous Au-Cu values in soil from sub-crop exposed by trenches in the southern target area. The combined geology, geophysical and geochemical signature patterns identify this area as a copper-gold porphyry target similar to one of the KSM deposits. Results from the 2018 VTEM survey will assist to refine the deposit model and identify potential drill targets.

COLE PROSPECT



Porphyry Copper-Gold

The Cole prospect is located at the northern extent of the 6-km long Hawilson monzonite. Metallis technical team during 2017 exploration program outlined a 400m x 200m wide area of gossanous, quartz-sericite-pyrite (“QSP”) alteration. This alteration is associated with the NNE-trending (015o) linear dikes of the Hawilson Monzonite hosted by Stuhini andesitic volcanics and unconformably overlaid by Hazelton siliciclastic rocks.

Alteration mapping indicates a zonation of quartz-sericite-pyrite (“QSP”) surrounded by propylitic, chlorite-epidote-carbonate alteration. The gossan within the QSP alteration are characterized by pervasive and locally boxwork hematite-Jarosite-limonite ± Mn-oxides.  The surface rock chip samples returned values between 0.2-0.9% Cu while soil values returned 300 to >600 ppm Cu and 100-500 ppb Au.

Exploration Potential

The Cole prospect is identified as the northern continuation of the 6-km long fertile Hawilson monazite with porphyry copper-gold mineralization analogous to the Kerr deposit at KSM. The Kerr porphyry deposit is hosted by similar north-south trending intrusive dikes and narrow stocks and contain a Measured + Indicated Resource of 378.4 Mt averaging 0.41% Cu, 0.22 g/t Au (source: Seabridge Gold Resource estimate Feb 2018, http://seabridgegold.net/resources.php). The 2018 exploration work program at Cole prospect is focused on

  • VTEM survey (83.3m line-spacing) to detect high-resolution magnetic and conductive anomalies associated with porphyry system.
  • Geological mapping and rock chip sampling of the porphyry and alteration zones.
  • Structural mapping of the “Adam fault-system” in line with geochemistry and VTEM results
  • Generating drilling targets based on field mapping, VTEM and geochemical anomalies.

 

NATT SHOWING



The Natt showing is located ~500m south of the King Target (outside the 2018 VTEM Central Kirkham block) and is hosted in a succession of volcanic flows, coarse pyroclastic rocks, mudstones, minor limestone and chert beds favorable for VMS style mineralization.

The host lithology and anomalous gold values in soil and rock samples of both the Etta and Natt prospects are being interpreted and tested as a vent proximal facies with a siliceous, shallow marine exhalative unit, comparable to the Eskay Creek host stratigraphy. Work during 2018 will integrate VTEM conductors to refine the targets and prospect model.

ETTA SHOWING



The Etta showing is located ~600m north of the King Target. The showing is hosted in a sequence of sedimentary rocks including a 20m thick argillite-siltstone unit with an underlying 2-5m thick argillaceous chert unit. A 300m long, south trending soil anomaly (Au, Ag, As and Zn) extends from the outcropping chert. Historic grab samples included a pyritic argillaceous chert which returned 0.29 g/t Au, and gossanous boxworks which returned 1.37 g/t Au.

The host lithology and anomalous gold values in soil and rock samples of both the Etta and Natt prospects are being interpreted and tested as a vent proximal facies with a siliceous, shallow marine exhalative unit, comparable to the Eskay Creek host stratigraphy. Work during 2018 will integrate VTEM conductors to refine the targets and prospect model.
