The Happy John 1 showing is located on the western side of Cass Creek, a few hundred metres north of the creek mouth. The Monitor mine (092C 007) adjoins the property. A number of old workings occur on the Happy John #1, #2 and #4 claims.

The area is underlain by rocks of the Upper Triassic Vancouver Group, comprising Karmutsen Formation volcanics and Quatsino Formation sediments, and 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.

There are 4 adits and opencuts on the Happy John #1 claim. These are centered on an area of altered limestone and volcanics containing pyrite and chalcopyrite. A sample from the workings assayed 12 per cent copper, 2.06 grams per tonne gold and 36.67 grams per tonne silver (Minister of Mines Annual Report 1906, page 193).

In 1986, Chelan Resources completed a program of geochemical sampling, geological mapping and ground geophysical surveys on the area as the Liquid Sunshine project. A 1.2 metre chip sample (LSC 21) of mineralized skarn material from the adit 1 portal assayed 10.8 grams per tonne gold. Other samples assayed up to 4.36 per cent copper (Assessment Report 15199).

In 1989, Chelan Resources and Nitro Resources completed a program of prospecting.

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, apart of the Nahmint property. In 2009, a select grab sample (200915) from a trench adjacent to the adit assayed 8.1 per cent copper and 35.1 grams per tonne silver (Assessment Report 31248). In 2010, a select grab sample (17305) from the fourth adit, located at 88 metres elevation, assayed 8.98 per cent copper, 0.126 per cent zinc and 19.5 grams per tonne silver (Assessment Report 31708).
