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. Several intrusions believed to belong to the Early Jurassic Texas Creek Plutonic Suite or the slightly younger Eskay Porphyry have been mapped across the property.

Location & Access



The Kirkham property is located approximately 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.

Sitting within the golden triangle Kirkham is 20 km southwest of Barrick’s Gold Corp’s past-producing Eskay Creek Mine and 40 km southeast from their past producing Snip Mine; 40 km from Pretium Resources’ Brucejack deposit and 30 km from Seabridge’s KSM deposits.

The closest road access is at the past-producing Eskay Creek gold-silver mine located 20 km northeast of the property up the Unuk River. Eskay Creek is connected by 60 km of controlled-access gravel road to Highway 37 a few kilometres south of the Bob Quinn Lake airstrip.

Currently, the 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 in the immediate vicinity of the 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:

(1) initial exploration of readily accessible areas in the 1920s and 1930s, on foot or using float planes out of Stewart;
(2) helicopter gossan reconnaissance in the 1950s and 1960s;
(3) porphyry copper exploration in the 1970s;
(4) intense exploration for gold starting in the early 1980s and culminating in the opening of the Snip and Eskay Creek mines in the early 1990s.
Immediately east of the southeastern corner of the Kirkham property, an 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) within a magnetite skarn adjacent to a diorite stock. Exploration for skarn and gold mineralization extended westward onto the current Kirkham property with extensive geological mapping, geochemical sampling and airborne geophysical surveys between 1987 and 1990 (Aussant and Dupre, 1989c, d, f; Cremonese, 1992; Cremonese, 1995; Dvorak, 1989b; Hawkins et al., 1987; Howson, 1991b; Wesa, 1990b, 1991). This work revealed sporadic gold-bearing silt and soil samples south of the Unuk River but no significant bedrock mineralization. Minimal work has been reported in this area since then (Harris, 2009; Kruchkowski, 1997).
Northerly-elongated claims in the central part of the property (Figure 2) comprise the Mt. Dunn property. In the late 1960’s, prospectors optioned the Mt. Dunn prospect to Skyline Resources Ltd. but no physical work was recorded for assessment and the claims lapsed in 1973. In 1974, Great Plains Development Company staked the Mt. Dunn prospect to the south of King Creek and in 1975 and 1976, collected soil samples on a 120 x 120 metre grid over the broad ridge-top between King and Fewright Creeks. The sampling defined a semi-continuous 200-300 m wide Cu-Mo soil geochemical anomaly (>180 ppm Cu, >7 ppm Mo), overlying a north-trending monzonite dyke (“Evan Dyke”), that is at least 2 km long and remains open to the south (Winter and McInnes, 1975). In 1976, Great Plains carried out mapping and several geophysical surveys (induced polarization, gamma ray spectrometry and magnetics). The IP survey indicated “an encouraging trend towards higher total sulphide, greater width and greater depth of mineralization in the southern part” of the grid (Mawer et al., 1977; Walcott, 1976). Great Plains chip sampled two outcrops and reported 0.60% Cu and 1.28 g/t Au across 18.9 m from one. Great Plains also staked the Cole prospect, (north of King Creek on the current Mt. Dunn property), and carried out a single day of work on it; highlighted by a soil sample that returned 2120 ppm Cu. Great Plains recorded no further work and allowed their claims over Mt. Dunn to lapse in early 1980.
In 1980, Du Pont of Canada Exploration Limited staked the Cole prospect on the basis of anomalous heavy mineral results from a regional stream sediment survey. The following year, they collected reconnaissance silt and soil samples and 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 showed a 100 x 600 m north-south Cu-Au soil anomaly (>250 ppm Cu, >100 ppb Au) over the ridge-top. A line of soil samples beside Gossan Creek extended this anomaly a further 700 m to the south but the anomaly remained open to the north and south. Du Pont discovered a massive pyrite boulder in Gossan Creek that returned 7.1 g/t Au, but did not find significant mineralization in outcrop (Korenic, 1982).
Placer Development Limited and Skyline Exploration Limited optioned Du Pont’s Cole claim in 1983 and carried out limited geochemical sampling that summer. Placer/Skyline’s work fleshed out Du Pont’s CuAu soil anomaly on the Cole prospect and revealed elevated Au, Ag, As, Zn in isolated soils 500 m west of Cole Lake (Gareau, 1983). In 1986 and 1987, Crest Resources Ltd. re-staked the Mt. Dunn (King claims) and Cole (Consoat claim) prospects and carried out limited prospecting and geochemical sampling of the lower Gossan Creek area from a camp on King Creek (Adamson, 1987).
In 1988, Cominco carried out 35 man days of mapping and geochemical sampling on the King and Consoat claims, focusing at lower elevations in the King Creek valley. Their mapping showed a major northsouth fault referred to as Gossan Creek Fault. Soil samples taken within 50 m of the fault were usually anomalous in all elements analyzed for (Au, Cu, Pb, Zn, Ag, As) and those taken greater than 200 m from the fault consistently yield values below the threshold of detection or have background to marginally anomalous values. Cominco reported massive pyrite lenses that returned up to 9.5 g/t Au and veinlets within argillaceous siltstone in the vicinity of the fault (Westcott, 1988).
In December 1988, Winslow Gold Corp., who had staked their Priam claims southwest of Crest’s King claims, commissioned an airborne geophysical survey which extended north as far as King Creek and covered the Mt. Dunn prospect (Dvorak, 1989b). In 1989, Winslow conducted prospecting and geochemical sampling over their claims, with the most promising results from the Priam Creek area. They identified altered and mineralized “quartz diorite” (monzonite) south almost to Fewright Creek, extending the probable extent of the Evan Dyke and prospect 1,000 m to the south (Aussant and Dupre, 1989c).
In 1989, Corptech Industries Inc. optioned the King and Consoat claims from Crest Resources and carried out a helicopter-borne VLF/magnetic survey over them. They established a new soil grid over the Mt. Dunn prospect, which confirmed Great Plains’ Cu-Mo soil geochemical anomaly and revealed a coincident, but slightly narrower, >100 ppb Au soil anomaly. They surveyed three reconnaissance IP lines across the Evan prospect and another over the Cole prospect. Although ground contact was difficult in the Evan zone due to sandy talus, the survey indicated two zones of high chargeability (>20 ms) near the eastern and western limits of the lines. Corptech drilled three holes (364 m) to test the western contact of the monzonite in an area of gold-bearing rock and soil samples and the western IP anomaly. The three holes cut pyritic, 12 silicified monzonite with the best reported intersection averaging 604 ppb Au over 14.5 m (Chapman and Dewonck, 1989; Chapman et al., 1989; Chapman et al., 1990).
Rimfire Minerals re-staked the Mt. Dunn property in 2002 and carried out limited fieldwork on the Mt. Dunn and Cole prospects that summer (Awmack, 2003). Paget Minerals Corporation purchased the Mt. Dunn property from Rimfire, carried out a rock sampling program in 2007 (Marsden, 2007) and drilled five holes (1,587 m) on the Mt. Dunn prospect in 2009, with their best intersection grading 0.13% Cu and 0.18 g/t Au over 332 m (Bradford, 2009). In November, 2013 Metallis Resources purchased the Mr. Dunn claims from Paget.
Achilles area
The Achilles prospect lies on two small claims (tenures 101637 and 101638) forming part of the Kirkham property east of the Mt. Dunn property. In 1989, this area was covered by an extensive airborne geophysical survey (Dvorak, 1989b). Between 1990 and 1991, Canadian Industrial Minerals Corp. completed geological mapping, trenching, rock and soil sampling in the area, concentrating on evaluating previously identified anomalies on both sides of King Creek. Four gold-in-soil anomalies (up to 3.3 g/t Au) were identified in 1990 (Wesa, 1990a). Samples from hand trenches returned 0.40 m @ 17.1 g/t Au and 6.0 m @ 2.0 g/t Au in two of these anomalies. Soil sampling south of King Creek identified a new 5.9 g/t Au soil anomaly but trenching did not uncover its source (Howson, 1991a). Prime Resources Group Inc. optioned the Achilles prospect in June, 1995 and carried out fieldwork that summer designed to evaluate the anomalies and mineralization found by Canadian Industrial. They confirmed the anomalies but believed that they were adequately explained by a small, weakly mineralized intrusion and let the option lapse (Kaip et al., 1995).
Eastern and Western Parts of Kirkham Property
In the late 1980s and early 1990s, several reconnaissance mineral exploration programs were carried out east of the Achilles prospect (Aussant and Dupre, 1989b, e; Dvorak, 1989b; Hawkins et al., 1987) and west of the Mt. Dunn property (Aussant and Dupre, 1989a; Nelles, 1990) with little success. Aerodat Limited carried out an airborne geophysical survey for Prime Explorations Limited in 1989 over much of the western part of the Kirkham property (Minfile, 2013). This survey comprised a fourfrequency AM system, a cesium vapor magnetometer and a two frequency VLF-EM survey. A total of 1,348 line kilometers were flown on east-west oriented lines at 100 m intervals (D. Dupré, pers comm, 2013).
Northern Part of Kirkham Property
In the late 1980s and early 1990s, reconnaissance mineral exploration programs were carried out over much of the northern part of the current Kirkham property (Brown and Collins, 1990; Dvorak, 1989a; Hawkins et al., 1987; Raven, 1990; Salat, 1989; Ven Huizen, 1991) with little success. It should be noted however, that none of these programs or those in the eastern and western parts of the Kirkham property were at all comprehensive or exhaustive

Recent Work (2013 - 2016)



  • Metallis purchased the group of claims comprising the property in July 2013. The original claim block was assembled by Dr. Rodney Kirkham (a world-renowned copper-gold expert) because of its excellent potential to host a wide variety of precious and base metal deposits.
  • In August 2013, Metallis carried out a 50 km2 airborne EM/Mag/Spec survey over a part of the property. This survey outlined numerous targets worthy of follow up.
  • On November 27, 2013, Metallis Resources expanded the Kirkham Property through the purchase of a group of mineral claims, the purchase was strategic in nature, as it was situated inside the Company’s existing Kirkham Property.
  • In June 2014, Metallis further acquired an additional 2 claims known as the Achilles and King Creek claims which were also situated within the existing Kirkham Property. A heavy mineral sample collected at the mouth of a stream that drains the new claims returned a gold assay of 3847 ppb – one of the highest recorded from the Golden Triangle.
  • In August 2014, Metallis commenced an exploration work program on the Company’s Kirkham Property in the Golden Triangle of northern British Columbia, focusing on the “King Anomaly”. The planned program comprises of geochemical sampling, trenching and geological mapping
  • In September 2015, Metallis completed an abbreviated 2015 exploration program on the Kirkham Property comprised rock sampling and geological mapping of the southernmost part (and lowest accessible elevation) of the Hawlison Monzonite, which intrudes rocks of the Stikine Terrane. This intrusion belongs to the Texas Creek Plutonic Suite which hosts most of the copper-gold mineralization in the Golden Triangle that has a mineral endowment exceeding 100 million ounces of gold within 50 km of the Kirkham Property.
  • The program also evaluated the Homer Prospect. A contour soil line was carried out between two soil lines from 1990 and 1991 that yielded anomalous Au values. The 2015 soil geochemistry produced elevated Au values in two neighboring samples, assaying 190 ppb and 450 ppb Au. Prospecting discovered a small gossanous outcrop of chloritized and pyritic andesite which returned 1.48 ppm Au and 3.1 ppm Ag.
  • In 2016, the Company 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 VTEM component of the survey is useful for delineating conductors (veins, massive sulphide lenses) down to ~400m below surface. Magnetics are useful for delineating structures and intrusions which are associated with porphyry copper-gold deposits of the Golden Triangle. Radiometrics may show potassic alteration which is associated with some mineralized occurrences. The 2016 survey identified four anomalies, which continue several hundred meters below the surface:

Fewright Creek: features an arcuate resistivity and magnetic anomaly surrounding a magnetic low. A small felsic plug has been mapped within this target. A large gossan occurs on the western side of the target. These features are interpreted to represent a classic alkaline porphyry copper-gold system that has experienced magnetite destruction in the center and propyllitic alteration around the rim. The geophysical results indicate that this anomaly increases in size with depth.

King East: 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: Are also characterized by coincident magnetic and resistivity anomalies. The propyllitic alteration minerals suggest that this target is high in the porphyry system. The geophysical modelling indicates the intrusion is quite near the surface.

 

The 2016 survey confirmed a fifth anomaly, a linear, very strong coincident resistivity and magnetic anomaly (King), originally identified by the 2013 survey, which is outboard from the mineralized Hawlison Porphyry. This feature is similar to the geological setting and geophysical response associated with the Snip Mine, located 40 kilometers 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.

All four of the coincident magnetic and resistivity anomalies fit Metallis’ model of the geophysical response from porphyry copper/gold deposits in the Golden Triangle. King East and Fewright Creek also have strong potassium anomalies. These anomalies are at least 2 kilometers in diameter, are near the surface and display proximal features such as small diorite stocks, propyllitic alteration and local mineralized veins.

CLIFF TARGET



Porphyry-Copper-Gold
  • The Cliff Target is characterized by an altered and mineralized Porphyry that is, about 6 kilometers long. The geological setting is strikingly similar to several of the KSM deposits, located 20 kilometers to the east of the Kirkham Property. Seabridge’s 2016 PFS incorporates KSM’s Proven and Probable Mineral Resources of 2.2 billion tonnes grading 0.55 grams per tonne gold, 0.21% copper and 2.6 grams per tonne silver.
  • The Hawlison Monzonite Porphyry was tested in 2009 with five shallow drill holes. These holes show that the copper and gold grades increase with depth. Drill hole MD-09-01, which most deeply penetrated the monzonite reported 92.67m @ 0.217% Cu and 0.277 g/t Au at the bottom. Rock samples show improving grades down section. At the lowest exposure, twenty-two rock samples (Cliff Showing – see Target #1 figure below) from the mineralized monzonite average 0.7 g/t gold and 0.35% copper. The magnetite, potassium feldspars, quartz veins, biotite alteration and mineralization distribution indicate that the lower part of the exposed Monzonite is proximal to the high-grade potassic core. Metallis plans to drill test the mineralized monzonite below the previous drilling intercepts.

KING TARGET



Shear-Vein 

  • The 2016 geophysical survey confirmed a planar, very strong, coincident resistivity and magnetic anomaly (King Target) that is outboard from the mineralized Hawlison Porphyry. The probable generator of this anomaly is a mineralized shear/vein system belonging to the “INTRUSION-RELATED Au PYRRHOTITE VEINS” type categorized by the BC Geological Survey.
  • A heavy mineral sample collected several hundred meters downstream from this target returned a very anomalous assay of 3847 ppb gold. Modelling of the geophysical responses indicate that they are related to a plate-like conductor that is approximately 400 m long, 15m thick and at least 220 m down-dip. This plate is 3 times the size of the Snip deposit, located 40 kilometers to the northwest of the Property. (See Geophysical Model of King Target below)
  • The Snip Mine is the best example of this class of mineralized deposits. From 1991 to 1999, the Snip Mine produced over 1.1 million ounces of gold, 429,000 ounces of silver and over 550,000 pounds of copper from 1.2 million tonnes.

OTHER TARGETS



In 2016, the Company 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 2016 Airborne Survey identified 4 new targets:

King East: 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. The Achilles showings and soil geochemical anomalies are situated within this area. This is an attractive target suitable for follow up as our 3 rd target.

Fewright Creek: features an arcuate resistivity and magnetic anomaly surrounding a magnetic low. A small felsic plug has been mapped within this target. A large gossan occurs on the western side of the target. These features are interpreted to represent a classic alkaline porphyry copper-gold system that has experienced magnetite destruction in the center and propyllitic alteration around the rim. The geophysical results indicate that this anomaly increases in size with depth. The resistivity anomaly is coincident with the southern part of the Hawlison Monzonite porphyry.

North and South Terwilligen: are also characterized by coincident magnetic and resistivity anomalies. The propyllitic alteration minerals suggest that this target is high in the porphyry system. The geophysical modelling indicates the intrusion is quite near the surface.

All four of the coincident magnetic and resistivity anomalies fit Metallis’ model of the geophysical response from porphyry copper/gold deposits in the Golden Triangle. King East and Fewright Creek also have strong potassium anomalies. These anomalies are at least 2 kilometers in diameter, are near the surface and display proximal features such as small diorite stocks, propyllitic alteration and local mineralized veins. Historically, very limited programs have been done in the areas around these targets which weren’t comprehensive nor exhaustive. These are attractive targets which are suitable for follow-up.
