The Happy John 4 showing is located on the southern slopes of Hecate Mountain, approximately 1 kilometre north west of the creek mouth of Handy Creek.

The area is underlain by rocks of the Upper Triassic Vancouver Group, comprising Karmutsen Formation volcanics and Quatsino Formation sediments, and by Lower Jurassic Bonanza Group volcanics. At the showings, these sheared and fractured rocks comprise limestone, argillite, andesite and a hornblende- granodiorite plug.

There are several mineral occurrences in the area; these occur in skarns, in areas of shearing and in areas of silicification. The geology and mineralization is very similar to that of the Monitor mine and may actually be the extension of the Monitor zones. One zone on this property, if extended along strike, would intersect near the Hedley orebody and, if projected to the shore of the canal, would terminate near the portal of the main adit on the Leonard orebody.

The Happy John #4 workings consist of a 15 metre long adit and a 5 metre trench near the portal of the adit, exposing limestone and skarn. An outcrop of siliceous volcanics hosting chalcopyrite and pyrite occurs 80 metres northwest of the adit.

In 1986, Chelan Resources completed a program of geochemical sampling, geological mapping and ground geophysical surveys on the area as the Liquid Sunshine project. Samples from the adit and trench assayed up to 5.46 per cent copper and 57.8 grams per tonne silver; while samples from the siliceous volcanic assayed up to 0.66 per cent copper, 13.5 grams per tonne silver and 9.9 grams per tonne gold (Assessment Report 15199).

In 1989, Chelan Resources and Nitro Resources completed a program of prospecting and geochemical sampling of 4 bulk samples. A 7.8 kilogram bulk sample (#201), taken from above the portal and containing partially banded pyrrhotite-marcasite-garnet skarn, assayed 0.12 gram per tonne gold, 6.5 grams per tonne silver and 0.09 per cent copper. The three other bulk samples collected assayed up to 0.265 per cent copper with lower results in gold and silver (Assessment Report 19484).

In 2007 through 2013, Nahminto Resources completed a program of prospecting, geological mapping, geochemical sampling, a ground magnetometer survey and airborne geophysical surveys on the area as the TJM claims, part of the Nahmint property. In 2010, a select grab sample (17238) yielded 8.2 per cent copper and 71.8 grams per tonne silver from a trench near the adit (Assessment Report 31708).
