The J grid was located on the north flank of Johns Peaks on the Coul 4 and Unuk 1 claims. Interest in the area was based on soils containing up to 120 parts per billion gold and rocks containing up to 0.40 gram per tonne gold collected in 1988 by Hi-Tec personnel (as reported in Assessment Report 19675). A portion of the grid was mapped and sampled but the soil sample results did not substantiate the anomalies outlined in 1988 by Hi-Tec. The area is underlain by Middle to Lower Jurassic Hazelton Group andesite, conglomerates, greywacke sandstones and siltstones. Granges Inc. who worked on the claim group from 1989 to 1994 assumed that gold-anomalous soils were being derived from northeast-trending structures interpreted from airphotos.

At the north end of the Triassic-Jurassic John Peaks diorite intrusions and in surrounding hornfelsed rocks of the Unuk Formation are abundant veins dominated by quartz and epidote. The abundance of sulphide-bearing boulders nearby suggests that a contact metamorphic zone exists around the intrusion (Assessment Report 22113). Sulphides are dominated by pyrite and pyrrhotite, with locally abundant sphalerite, galena and chalcopyrite.
