Capsule Geology

A Triassic or younger granodiorite to quartz diorite stock intrudes the Upper Triassic Stuhini Group volcaniclastics and sediments. Triassic diorite of the Stikine or McQuillan Plutonic Suite intrudes the strata.

Skarn-type mineralization including magnetite, chalcopyrite, specularite and pyrite is localized within Triassic interbedded limestones near the contact with the quartz diorite.

In the eastern part of the Har claims, sericite, chlorite and biotite schists are interbedded with limestones and minor black argillite. To the west, hornblende diorite and quartz diorite intrude these sediments. In 1960, a rusty zone within sheared diorite on the south side of the Unuk River was mapped. The diorite was described as being heavily carbonitized with iron-bearing carbonate and hosting disseminated specularite with up to 10 per cent pyrite. In other places, the massive diorites are carbonized and host sporadic malachite staining.

Opposite the mouth of Harrymel Creek, a small north-northwest trending fault cuts the diorite. A magnetite-epidote-garnet skarn has developed along this fault within altered andesitic schists and garnet-bearing schists. The skarn hosts abundant disseminated magnetite, specularite with pyrite and chalcopyrite (Newmont Map, Property File).

Work History

The 1989 exploration program by Winslow Gold Corp on the Iliad 2 and 3 claim (Iliad South) consisted of helicopter-supported reconnaissance prospecting, geological mapping, and geochemical sampling (Assessment Report 19681). A total of 12 rock, 9 stream silt, and 2 heavy mineral samples were collected. The Har showing, reportedly located near the area, was not re-located during the current exploration program. However, a grab sample of rusty weathered quartz diorite located near reported location of the Har yielded 0.11% copper (Assessment Report 19681).

In 1989 a limited amount of assessment work was completed on the Cop, Har 1 and 3 claims for Westmar Resources Ltd (Assessment Report 19813). A total of 15 rock chip samples were collected but no anomalous results were obtained.

In 1990, Kinghorn Energy Corp collected 147 rock samples and 3 pan concentrate samples the Cop, Har 1 and 3 claims (Assessment Report 21463).

In 2006 and 2007, Hathor Exploration Ltd. completed a 7228.7 line-kilometre airborne geophysical survey on the area as the Hawilson claims of the Iskut project. In 2008, Max Minerals Ltd. examined the property.

In 2010 soil sampling in the Max deposit area by Max Minerals Ltd (later known as Standard Exploration) area was focused on further delineating mineralization on the Max (104B 013), Har and Chris (104B 125) grids and to allow for correlation with any anomalies found on the magnetometer surveys (Assessment Report 31747). The overall geochemical 2010 outlook on the area indicated there was a limited extent of precious metal distribution surrounding the Max deposit. Rock geochemistry does not indicate significant Au associated with the Max deposit but mapping indicates Cu associated with the Max deposit is focused along the periphery of and within the iron skarn, much like the geochemistry indicates.

Anomalous gold±silver±cobalt±copper are patchily distributed throughout the Har grid and could be related to small iron skarns, associated with the diorite intrusion that is in contact with Stuhini Group sedimentary rocks for 500 m by 850 metres of the grid. However, there is no visible trend apparent in the distribution of the geochemical anomalies and they do not correlate with the geology. Additionally, the Har showing is not apparent from the geochemistry and represents a small iron skarn.

The Har grid has a weak magnetic high in the vicinity of the historic Har showing. The magnetic high is 300 by 450 metres and trends 210 degrees. Several smaller magnetic highs exist on the grid; however they are limited.

During the 2010 program this area was not re-located, however a small zone of granodiorite hosting a feldspar porphyry with disseminated pyrrhotite and pyrite was encountered.
