Geology: The Kirkham property lies within the Stikine Terrane, near the boundary between the Intermontane and Coast Tectonic Belts of the Canadian Cordillera. Locally, the Kirkham property lies on the western margin of the Eskay Rift with trans-tensional structures host to several metallic ore deposits in the district. 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 centered 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 kilometers south of the Bob Quinn Lake airstrip. In recent years, several infrastructure improvements have been made in the region, including 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).

Summary of Historic Exploration Work (1960-2009)

Metallis Exploration Work and Results 2013-2018

  • In 2013, Metallis Resources acquired the Kirkham property. A 50 km2 airborne EM/Mag/Radiometric survey outlined severalgeophysical targets in the eastern claims. Metallis expanded the property by the acquisition of all other claims situated inside Kirkham Property.
  • In 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. Metallis commenced an exploration program focused on the “King Anomaly” and carried out regional mapping, sampling and trenching.
  • In 2015, Metallis conducted geological mapping and sampling over the southernmost part of 6.5 km long Hawilson Monzonite. 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. Evaluation of the Homer prospect and soil geochemistry indicated 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.
  • Metallis Resources Inc. in 2016, engaged Geotech Ltd to conduct a VTEM/magnetic/radiometric survey over a 6000 hectare of the property, which was not surveyed in 2013. The results were interpreted for conductors related to massive sulphide lenses as well as delineate structures and potassically altered and mineralized intrusions using magnetic and radiometric signals.
  1. Fewright Creek represents an arcuate resistivity surrounding a mag-low that coincides with phyllic alteration, gossan, and a small felsic plug reflecting a
    porphyry Cu-Au system.
  2. King East represent a large mag-high and resistivity-lowanomaly correlated with gold-bearing veins and felsic dikes mapped in the southern part of this
    target.
  3. North and South Terwilligen represent coincident magnetic and resistivity anomalies, along with propylitic alteration in the area indicate a high-level
    porphyry system.
  4. King Target represent a linear coincident resistivity and magnetic anomalywithin a geological setting similar to the Snip Mine, located 40-km to the
    northwest. The pyroclastic dome, limestone and mineralized chert layers reflect VMS style mineralization as in the Eskay Creek.
  • Metallis Resources Inc. in 2017 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). Meanwhile, Metallis’
    geologists reviewed several other targets including
  1. Porphyry Cu-Au mineralization at Camp, Cole, King E and Terwilligen prospects
  2. Magmatic Ni-Cu mineralization at Thunder North and Thunder South
  3. VMS/Shear vein Au at the Natt, King and Etta prospects (Razique & Weatherup 2017).
  • Based on the results from 2017 exploration and drilling program, Metallis Resources in 2018 conducted multiple high resolution VTEM surveys to identify conductors associated with porphyry Cu-Au, VMS-Shear vein Au and magmatic Ni-Cu mineralization throughout Kirkham Property. Metallis drilled 12 diamond core holes (>5000m) which expanded the Cliff target and discovered 2 gold-rich porphyry centers including Nina and Cole currently ranked as high-priority targets.

CLIFF TARGET



Porphyry-Copper-Gold

 

Geological Framework



Cliff is a large porphyry Cu-Au system extended over an area of 3.0 km x 0.5 km along the southern portion of 7.5 km long Hawilson Monzonite complex. The Cliff porphyry complex is proximate to the Triassic-Jurassic unconformity, referred to as the “Red Line” (Kyba 2014) an important geological horizon for copper-gold mineralization in the Golden Triangle.

Porphyry Cu-Au mineralization in Cliff is associated with ~400 m wide and 3 km long, N-S trending corridor of Jurassic age (191 Ma) monzodiorite porphyry intrusions and igneous-hydrothermal breccias hosted by upper Triassic Stuhini andesitic and clastic sedimentary rocks.  Porphyry intrusions are characterized by variable proportion of plagioclase feldspars and amphiboles as well as hydrothermal biotite, chlorite-sericite and sericite-clay minerals and a microcrystalline groundmass. The igneous breccia with porphyritic clasts and matrix are linked to the monzodiorite and diorite porphyry intrusion. These porphyry intrusions and breccias exhibit potassic and sericitic alteration, quartz-carbonate veins and sulfides, subsequently cut by narrow feldspar porphyry and barren microdiorite dykes.

The structural setting and the interplay between porphyry intrusions, breccias and episodic hydrothermal events are responsible for the gold-rich mineralization at the Cliff target which remains open in all directions”. These geological characteristics, metallogeny and copper-gold grades at Cliff porphyry system are similar to the Kerr Deposit of Seabridge Gold’s KSM project, which has an inferred resource of 1.92 billion tonnes grading 0.41% copper and 0.31 g/t gold, containing 19.0 million ounces of gold and 17.3 billion pounds of copper (Seabridge New Release Feb 16, 2017).

2018 Exploration and Drilling Program



The 2018 exploration program at the Cliff target comprised 6 deep diamond drill holes totaling 3,062 meters, yielding intervals of significant gold-rich mineralization. The drilling assays confirmed the continuity of copper-gold grades associated with multiple porphyry intrusions and hydrothermal events in the Cliff target, extending over a strike-length of 3 km, at the southern end of the 7.5 km long Hawilson monzonite.  The Cliff target is identified as a unique porphyry system with three distinct styles of copper-gold mineralization given below in chronological order.

  • Extensive gold-copper intervals (ie: 141 meters of 0.4 g/t Au and 0.23% Cu in hole KH18-16) are associated with a swarm of potassically altered Hawilson Monzonite dikes.
  • Broad intercepts of gold-rich mineralization such as 37 meters of 1.54 g/t Au and 0.05% Cu in drill hole KH18-14 are linked to secondary hydrothermal event of intense quartz-carbonate veins and highly silicified hydrothermal breccias along the contacts with the Hawilson Monzonite dikes.
  • Localized 1-3 meter intercepts with gold grades up to 3.0 g/t Au are associated with late-stage quartz-carbonate and massive sulphide veins of pyrite-pyrrhotite-chalcopyrite mineralization.

A summary of the 2017 & 2018 drilling results are tabulated below. All other maps and figures including geological cross section and model is given in the photo galleries.

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.

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.

  • 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.

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 TARGET



Porphyry Copper-Gold

Geological Setting



The Cole Porphyry system defines the northern extent of the 7.5 km long Hawilson Monzonite (‘HM’). The 2017 exploration work outlined a 400m x 200m wide area of gossanous, quartz-sericite-pyrite (‘QSP’) altered diorite and monzodiorite porphyry intrusions. These intrusions are emplaced as NNE-trending (015º) linear dikes hosted by Stuhini andesitic volcanic rocks and unconformably overlaid by Hazelton rocks to the west. The gossan within the QSP alteration are characterized by pervasive and boxwork hematite-jarosite-limonite ± Mn and Cu oxides.  The historic surface rock samples with 0.2-0.9% Cu and soil with 300 to >600 ppm Cu and 100-500 ppb Au well correlate with the QSP alteration.

2018 Drilling and Exploration Program



The 2018 geological mapping program identified Cole as a typical sub-alkalic porphyry copper-gold target with the alteration footprint extended for 1000 x 800 meters that has never being drilled. The mapping indicated a zonation pattern of QSP alteration surrounded by propylitic (chlorite-epidote-carbonate) alteration. The Cole porphyry intrusions including diorite and monzodiorite transition outward into massive sulphide and epithermal style sheeted quartz veins.

Metallis’ 1st ever drilling campaign in Cole target this year consisting 3 drill holes totalling 1302 meters discovered a series of NS-trending mineralized porphyry dikes, hydrothermal breccias and massive sulphide veins cutting across the volcano-sedimentary rocks of Stuhini formation. The cm-scale massive sulphide veins in both KH18-18 and KH18-19 drill holes appear similar to the gold-bearing veins found in Snip mine, which produced 1.1 million ounces of gold at an average grade of 27.5 g/t from 1991 to 1999 (MINFILE, 2015: Snip, 104B 250; BC Ministry of Energy and Mines).

The drilling assays at the Cole target indicated a high-grade gold zone containing 11.18 g/t Au over 7.7m including 137 g/t Au over 0.6m. Some of the significant assay results and control of mineralization is given below.

Drilling Highlights



KH18-18 intersected porphyry style mineralization in shallow quartz stock work zones and sulphides carrying 0.94 g/t Au over 9m and 0.42 g/t Au over 10m. Alteration patterns in the core, geology and geophysics all vector towards a mineralized system to the southeast.

 KH18-19 discovered a high-grade zone of 11.18 g/t Au over 7.7m including 137 g/t Au over 0.6m associated with shallow, intrusion-related massive sulphide veins. These veins transition outward into epithermal sheeted veins located at the Etta target to the west. (MTS New Release – Nov 20, 2018). 

KH18-20 was drilled along and across the Adam fault cutting through a series of 4-9m gold intercepts ranging from 0.40 to 0.74 g/t AuEq, associated with similar centimeter-scale massive sulphide veins as in KH18-19.

A summary of the 2018 assays are tabulated below. Additional information including geological maps, cross section and field photographs can be found in the galleries.

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 TARGET



On November 20, 2018 Metallis announced results of the 2018 Field Mapping Program which resulted in a new gold/silver discovery at the Etta Target.  The Etta vein discovery occurs at the northern end of the 7.5km long mineralized Hawilson Monzonite Porphyry Complex, west of the Cole target. 

Highlights:

  • A rock chip sample (Y060741) from a newly discovered vein assayed 13.2 g/t Au, 795 g/t Ag, 0.5% Cu and 1.3% Zn while a wall-rock chip sample half a meter away returned 1.14 g/t Au, 1.18% Cu and 67 g/t Ag, see photo of sample below;
  • Gold mineralization at Etta is hosted by several parallel, tabular north-south trending veins of bull-quartz-carbonate with native gold, electrum a chalcopyrite. These veins are emplaced in a phyllic alteration zone around the periphery of the Hawilson Monzonite;
  • A historic copper-gold and silver-lead-zinc soil geochemical anomaly extends over an area of 700 meters by 300 meters and is open for expansion; and
  • The rocks at Etta are characterized by sheeted drusy quartz veins exhibiting typical gold pathfinder mineralogy associated with epithermal systems.

During the 2018 field mapping program, a steeply dipping epithermal vein with ~10 meters strike length and ~0.5 meter width, was discovered on a north facing cliff at the Etta target. The quartz-calcite vein demonstrates drusy textures and remains open along strike. The discovery has led the geological team to re-interpret the historic geochemical anomaly at Etta as part of an epithermal system proximal to the Hawilson Monzonite porphyry.

Dr. Abdul Razique, Metallis’ Chief Geologist, commented: “Etta represents an exciting new prospect that fits the classic epithermal model that hosts many significant deposits throughout the Cordillera of North and South America.  Such a zone typically forms as the uppermost shell above or distal to a sub-alkaline porphyry deposit. This has us more encouraged than ever about the high-grade gold and large-scale porphyry potential at Kirkham.”
