Blunt Mountain (Hazelton)


Blunt Mountain AOI is one of four areas of interest hosted on Jaxon’s Hazelton property, located 45 km north of Smithers in British Columbia. Situated on the northeast corner (Figure 1) and spanning 70.62 km2, Blunt Mountain is a newly consolidated project area comprising ten previously held claims, one newly acquired claim (#10646260) and one split claim (#1073848).

After reviewing historical prospecting, staking, geological, geophysical and geochemical exploration data and completing a small scale surficial sampling program in 2017 and 2018, the Company remodeled a selection of historical results and identified the outlines of a potentially large and deep-seated Cu-Mo porphyry system indicated by a significant magnetic anomaly. Based on those modeling results, the project area was expanded, consolidated and defined as its own AOI. Blunt Mountain is located at the centre of the Skeena Arch Bulkley intrusions. The Company is studying the extent of any impacts from Laramide events on porphyry generation in the area (Figure 2).

Exploration History

A 1984 government geochemical survey indicated a stream sediment sample from Skilokis Creek with anomalous silver, lead, arsenic and antimony values of Ag 3.6 ppm, Pb 85 ppm, As 225 ppm and Sb 7ppm. The general source area was staked by Atna Resources Ltd. (Atna) and Noranda Exploration (Noranda) in 1984 and 1985. In 1985, both companies located mineralization in a tributary (Clay Creek) of Skilokis Creek and in a cirque to the northwest, the headwaters of Ferri Creek.

In late 1985, a 50-50 joint venture agreement between Atna and Noranda was signed and limited exploration carried out. Work included 105 soil samples, 55 rock samples, 20 silt samples and two stream sediments. The results involved discoveries of five sulfide mineralized zones: Pat, H, B, C and D, with rock samples values as high as 26.5 g/t Au, 13% As and 1400 g/t Ag. The mineralization was found to occur in quartz veins or altered granodiorites (Figure 4).

In 1986, Noranda completed a large program including prospecting, soil, silt and rock geochemistry, geological mapping, ground magnetic and VLF-EM surveys, hand trenching and diamond drilling (three holes totaling 191.7 m).

Highlights and comments from the program:

  • Two narrow mineralization intersected along widely sheeted joints in hole BM86-1: 25.75-26.05m at 2.43 g/t Au, 65.1-65.2m at 1.37 g/t Au. Total of 192 m drilled for three holes. Hole BM86-2 was obviously parallel to the mineralization zone and within the mineralization barren zone. Hole BM86-3 was too shallow to reach the mineralization zone (Figure 5).
  • Abundant mineralized float found on surface, the best float sample 86820 returned 2.33 g/t Au and 585 g/t Ag.
  • Two rock types encountered in the drill hole: 1) feldspar porphyry and 2) monzonite, diorite.
  • The gold mineralization zones in BM86-1 may represent a distal sulfide vein type gold mineralization within the magnetic low area based on the preliminary magnetic and soil sampling program (Figure 6). The future drill program should target the transition area between the magnetic high and magnetic low areas.

The Blunt Mountain AOI is underlain by clastic sediments of the Jurassic Bowser Lake Group which are intruded and hornfelsed by a monzonitic to dioritic pluton of the Late Cretaceous Bulkley intrusive which is cut by granite of unknown age and by intermediate, feldspar porphyry dikes. Several types of alteration and mineralization have been discovered on the property. The most important type is Ag-Au-Fe-Pb-As-Sb-Zn mineralized quartz veins.

(1986 Assessment Report)

In 1987, work included grid extensions and additional geochemical sampling, 31 hand-dug trenches and three diamond drill holes totaling 186 m (Figure 5).

BM87-1 and BM87-2 with drilled depths of 59.1 m and 82.3 m, respectively, had almost no mineralization at the Mound Vein showing. BM87-1 intersected two clay altered zones at 35.7 m to 43.6 m and 53.3 m to 54.9m, respectively, with low grade silver (< 6g/t) and negligible Au grade (<0.07 ppm). Hole BM87-2 intersected two clay alterations at 50.2 m to 51.2 m and 70.1 m to 80.8 m. No significant mineralization was found with these clay zones. Minor chalcopyrite-pyrrhotite mineralization in quartz-chlorite veinlets occurs above and below the first zone of clay alteration. If an eastward dip is assumed for the Old Mound Vein, then it is possible that hole BM87-2 was not drilled deep enough.

BM87-3 intersected the Ferri Creek Vein about 12.5 m below surface but recovery was so poor that both the width and grade of the intersection were uncertain. A sludge sample graded 0.38 gmt Au and 84.0 gmt Ag over 1.25 m. A very steep dip is indicated for the Ferri Creek Vein.

Three major lithological units have been discovered in the three drill holes:

Hornfels clastic sediments

This is unit 3 of Myers (1987), the oldest unit in the area. Sand to claystones of the Bowser Lake Group are contact metamorphosed to gray coloured, brown weathering, biotite and biotite-garnet bearing hornfels which in these three drill holes are highly fractured. Core recovery averaged around 30% near surface and 75% deeper, below intrusive units.

Intermediate Feldspar Porphyry

This is unit 2 of Myers (1987). It is typically a very fine grain, light greenish gray intrusive rock found as dikes cutting all other units. It may contain white to gray or epidotized feldspar phenocrysts to 3 - 4 mm across. It commonly has dark green chlorite after amphibole grains to 2 mm across or with biotite to 3 mm across. In places this unit can be confused with a fine grain, porphyritic variant of the monzonite or granodiorite unit which was not intersected in these diamond drill holes. Recovery in this unit averaged about 80%.


This is a green and gray mottled rock with fine grain contacts. The diorite in hole BM87-3 has medium grained white feldspar crystals. This is probably a border phase of the Blunt Mountain batholith (unit 1 of Myers, 1987). Recoveries ranged from 45% to 100% in this unit.

It seems there are similar issues for the 1987drill holes. They are either drilled in the wrong dip direction and azimuth or are too shallow. Future drill holes should be moved closer to the intrusive and drilled deeper (Figure 7).

In 1990, a brief site visit was made and nine rock geochemical samples were collected for analyses.

In 2005, G.E. Nicholson made a one day visit to the property to determine the access and logistics, conduct a general view of the geology and to make recommendations for future work.

In 2006, prospectors L. Stephenson, M. Nelson and Richard Simpson spent three days on the property and collected 52 rock samples on six traverses. 36 of the samples were from outcrop and 16 floats. All samples were analyzed by ALS Chemex of Vancouver and six samples were submitted to Vancouver GeoTech Labs for petrological descriptions.

Results in 2006 indicate that the galena vein, known as the Mound Vein, contains a significant quantity of Au and Ag along with Pb, Cu and Zn. Results from analyses of samples collected over the four traverses indicate that precious metals have ranges from 10 ppb to 1,500 ppb Au and from 0.05 ppm to 5,410 ppm Ag. The deposit is a polymetallic, Pb-Cu-Mo-Zn-Au-Ag, vein system that might be related to a porphyry system in the area.

In September 2014, a surficial exploration program was completed on the Mineral Hill Property (Figure 8). The program focused on prospecting and sampling the ridge south of the old camp, prospecting and sampling the cirque around the old camp and limited sampling of core stored at the old camp site.

The 2014 surface program focused on taking rock samples from sites containing visible sulphides, quartz veining and limited sampling of historic diamond drill core. Rock sampling confirmed historic results of anomalous lead and zinc values; these may be indicative of a hidden porphyry system.

Geology of Blunt Mountain AOI

Blunt Mountain lies within the Intermontane Belt of British Columbia. The Skeena Arch, a broad structural high trending north easterly, underlies the area.

Sedimentary rocks of the Middle Jurassic to Late Cretaceous Bowser Lake Group and Kasalka Group underlie the AOI. The Late Cretaceous Bulkley intrusives intrude both these groups. A brief summary of the two groups, taken from Maclntyre et al. (1994) is given below (Figure 9).

Undivided Bowser Lake Group (mJKBo) - interbedded epiclastic feldspathic wacke and volcanic conglomerate, sandstone, siltstone, mudstone, shale and argillite; minor coal and carbonaceous units; minor basalt and andesite flow, breccia and tuff, dacite lava, lapilli tuff (Maclntyre et al., 1994; Geoscience BC, 2010).

Kasalka Group (uKks) unnamed equivalents-hornblende- feldspar porphyritic andesite to basalt flows and related pyroclastics, breccias and epiclastic beds, lesser dacite, rhyodacite, basaltic andesite, quartz porphyry; sandstone, conglomerate (Geoscience BC, 2010).

Bulkley Intrusions (LKg) - biotite-hornblende granodiorite to quartz diorite, diorite, quartz monzonite, rhyolite and quartz-feldspar porphyry, biotite-hornblende feldspar porphyry, biotite-feldspar porphyry, hornblende-feldspar porphyry; minor andesite felsites, aplite, alaskite and intrusive breccia; stocks, plugs sills and dykes; 64 to 84 Ma (Maclntyre et al., 1994; Geoscience BC, 2010).

Figure 9: Simplified Geology Map of Blunt Mountain AOI (Geoscience BC, 2010)

The sedimentary rock adjacent the intrusive contact has been converted to hornfels. North trending feldspar porphyry and quartz feldspar porphyry dykes transect the area. The polymetallic mineral showings occur mostly in the hornfels along a north-easterly trending structure which transects both rock types. The Cu-Mo porphyry mineralization showings exist in the nearby Bulkley intrusives in the project area. Two types of mineralization, copper-molybdenum porphyries and silver-gold-lead-zinc veins, have been discovered at the Blunt Mountain AOI.

Magnetic Features

In 2010, Geoscience BC completed the QUEST-West Project, a 1:500,000 aeromagnetic survey program conducted in central west B.C., which includes Jaxon’s Hazelton property area (Figure 10).

There is a strong positive magnetic anomaly area in the north-west part of the Red Springs AOI and south-east part of Blunt Mt AOI. The historical mineralization showings and workings were focused on the medium and low positive magnetic anomaly area at Blunt Mountain, which is similar to Red Springs, south of Blunt Mountain and Netalzul Mountain AOI in the north-east corner of the Hazelton property.

The Company notes that to date, there have been no historical mineral showings or MINFILEs recorded at the magnetic high area.

(Quest-West Project, Geoscience BC, 2010)

A detailed aeromagnetic survey was conducted in the historical showings area of the Blunt Mountain AOI in 1986 by Noranda and Atna (Figure 11). It generally coincided with large regional magnetic survey results. The historical drilling was focused on the magnetic low area at Blunt Mountain.

Figure 11: Detailed Local and Regional Magnetic Anomalies Map of a portion of Blunt Mountain AOI


Mineralization in the region consists most commonly of copper-molybdenum porphyries and fracture controlled or epithermal sulfide mineralization veins. The veins are silver, gold, lead and zinc bearing and are the distal sulfides mineralization related to the deeper Cu-Mo porphyries in the Bulkley intrusion.

Historical assay results indicate a mineralization corridor along or near the contact zone between the granodiorite intrusive and hornfels sedimentary rock with up to 29.34 g/t Au, 5410 g/t Ag, 4478 ppm Cu, 4000 ppm Mo, 10% Pb, 8.2% Zn and 3.8% Sb (Table 1 and Figure 12).

A total of thirteen showings were identified from previous exploration. The showings are either copper-molybdenum porphyries or Ag-Au-Pb-Zn-Sb veins related to various Late Cretaceous Bulkley intrusive, forming a north-easterly trending mineralization corridor approximately 4 km long and 150 metres wide (Figure 12). Within the corridor, veins are occasionally exposed on surface, forming a continuous line or an en-echelon system. Veins dip steeply and several veins are exposed by historical trenching over tens of metres. The mineralization is associated with concentrations of galena, sphalerite, pyrite, arsenopyrite and stibnite in quartz and tourmaline veins and associated silicification. Adjacent rocks are altered intrusive or hornfels sedimentary rock.

Table 1: Polymetallic element assay results from historical assessment reports

Best chip sample results to date report 4.05 g/t Au over 1.2 m from the Ridge Vein and 5.62 g/t Au over 1.6 m from the Old Post Vein. Gold is found from 0.2 to 9.05 g/t and silver from 2.68 g/t to 1400 g/t in showings over varying thicknesses of 0.3-1.2 m. Six drill holes totalling 378 m tested showings. Due to technical drilling problems, recoveries were generally low.

Figure 12: Outline Map of Geology, Mineralization and Historical Showings at Blunt Mountain AOI

The Company conducted a field prospecting program in the 2017 and 2018 field seasons collecting 19 outcrop chip and grab samples (Figure 12 and Table 2).

The granodiorite intrusive is cut by a well-developed set of sheeted joints at an approximate 40 degree strike and is mineralized with amphibole-quartz-magnetite-apatite-sulfide vein. The veins may be zoned and laterally change to predominantly quartz-arsenopyrite-tourmaline vein.

Assay results from outcrop grab and chip samples taken during the 2017 and 2018 field seasons are up to 1886 g/t Ag, 5.45 g/t Au, 2413 ppm Cu, 217ppm Mo, >1% Pb, >1% Zn and >1% Sb (Table 2). These results confirm the historical assay and existence of a distal Au-Ag-Pb-Zn-Sb sulfide vein mineralization. The historical air magnetic anomalies outline the transition zone between the magnetic high to magnetic low, along the contact zone of Bowser Lake sedimentary rocks and Bulkley Creek intrusive. The developed quartz vein type polymetallic mineralization is overprinted near the contact intrusive and sedimentary rocks, interpreted as potential to host a hidden porphyry type Cu-Mo-Au-Ag mineralization along the magnetic transition belt at the Blunt Mt. AOI.

Conclusions and Work Plan

The surface program focused on collecting rock samples from sites containing visible sulphides and quartz veining. This sampling confirmed the historically observed anomalous lead and zinc values. Surface and remote geophysics revealed significant regional and local magnetic anomalies, features of the Bulkley intrusive. The results are signatures of one or more deep, hidden porphyry systems at Blunt Mountain.

The 4 km long and up to 150 m wide vein system is believed to represent a surface expression generated by a large porphyry intrusive system. Numerous feldspar porphyry dykes were discovered in close proximity to the sulfidation vein mineralization and to the distal large propylitic alteration halo in the east part of the area (Figure 13), extending to the east section of the Red Springs porphyry system. The porphyries at Blunt Mountain could potentially be part of the same system and may be related to the same ore-forming processes. This possibility will be examined in the course of future exploration.

Future Exploration Work

  • Conduct comprehensive geological mapping and a rock sampling exercise using the locations of the known showings and collars from the historic diamond drill holes. Expand the mapping to cover the unexplored top part of Blunt Mountain where the Bulkley intrusive is prevalent. Geological mapping and rock sampling programs will follow the known veins and structures, identify new veins and define new areas for additional exploration (Figure 13)
  • The Creek showing (MINFILE 093M140), approximately 2 km south-east of the main showing, is a molybdenite occurrence hosted in a contact zone between Bulkley intrusion and Late Cretaceous hornfels on the west side of Blunt Mountain. Geological mapping and rock sampling are planned for this area (Figure 13)
  • Exploration and comparison of mineralization between Blunt Mountain AOI and Red Springs AOI; comparison with the propylitic alteration zone from Red Springs to Blunt Mountain (Figure 14)
  • 50:50 m grid soil sampling program in the proposed working area
  • Drone based aero-borne magnetic survey in the proposed working area
  • 1000-2000 m drilling program in the selected porphyry and polymetallic mineralization targets to follow field work
