The Johan occurrence is located approximately 4 kilometres southeast of Goldway Peak and is within 3 kilometres of the Bruce (094D 013) and Goldway (94D 027) occurrences.

The occurrence is hosted within a quartz-carbonate altered zone of the Middle Triassic to Lower Jurassic Takla Group volcanics and sediments. The strata strikes north, dipping predominantly to the east. Locally, sericite and ankerite altered tuffs hosts quartz-calcite veins with gold values. The controlling structure of the veins is a northeast trending fault that parallels an informally named (Mariposite) creek. The veins have been traced for over 80 metres.

At Mariposite Creek an east-west trending sheeted vein set, consisting of 1.0 centimeter to 3.0 metre wide quarlz +/- carbonate veins spaced approximately 1-5 metres apart is exposed over a 125 rnetre width. Mineralization within the veins consists of traces of pyrite along with rare galena-sphalerite-chalcopyrite. Wallrock to the veins is commonly iron-carbonate altered and weakly pyritized. Although previous rock sampling in this area reportedly returned up to 15.5 grams per tonne gold across a 1 metre quartz vein (Assessment Report 24138 (Hemlo Gold)), the two grab samples of quartz vein material taken from this area during the course of the 2013 program returned only 0.535 and 1.43 5 grams per tonne gold (Assessment Report 34436). A single north-south trending soil sample line designed to cross-cut the sheeted vein set shows highly anomalous values of from 0.344 parts per million to 0.394 parts per million gold along the southernmost 65 metres of line, with the anomalous length of the line remaining open to the south (Assessment Report 34436).

In 1985, a sample from a large quartz vein assayed 0.7 grams per tonne gold (Assessment Report 13697).

In 1995, a grab sample (GG0521) from a 1.0 metre quartz pod assayed 15.55 grams per tonne gold and 13.6 grams per tonne silver (Assessment Report 24138).

In 1985, BP Resources completed a program of geological mapping and rock, silt and soil sampling on the area as the Goldway claims. In 1994 and 1995, Hemlo Gold Mines completed programs of rock and soil sampling, geological mapping and a ground magnetic survey on the area as the Dort 1-4 and Jo 4 claims. In 1996, Catalyst Ventures, on the behalf of Battle Mountain Gold, completed a program of geological mapping and rock sampling. In 2012, J.B. Kreft prospected the area.

In 1994, Hemlo Gold worked on the KPO, GV , Creek and TF zones and Maraposite Creek and Hemlo Drilling collected a total of 717 soils and 195 rocks samplesand and constructed 32.4 line kilometers of grid. 29.05 line kilometers of magnetometer surveying was later completed on the property. This work resulted in the definition of a 3 kilometre long and 500-1000 metre wide zone of quartz veined and fractured ankerite and sericite-altered, pyritized andesite tuffs semi-coincident with a greater than 100 parts per billion gold-in-soil anomaly (Assessment Report 23682).

In 1995, Hemlo Gold Mines Inc. continued work on several of the properties described in 1994. Drilling was completed on the Soup and Granite Basin projects while further geological and geochemicalsurveys were conducted on the Darb and Mariposite projects.

In 1996 Battle Mountain Canada (formerly Hemio Gold Mines lnc.) drilled 461 metres in 2 diamond drill holes on the Mariposite Property (Assessment Report 24778). The program was conducted in order to test amomalous gold in talus line anomalies associated with quark-quartz/calcite stockworking hosted by sericite-ankerite plus/minus biotite -altered andesite volcanics and epiclastics. The drill program incorporated geological and geochemical data collected during the 1994-1995 field seasons. Drill results are discussed in Mariposite (094D 202).

The 2012 field work of Bernard Kreft focused on the area immediately surrounding the Johan minfile occurrence (Mariposite), though the Dort property claims covered most of the historical showings west and south of Johanson Lake. A one day helicopter supported field geochemistry and prospecting program was conducted. Five out of the eight silt samples collected returned gold values of less than 100 parts per billion gold. One rock sample obtained from a quartz vein returned 0.142 gram per tonne gold over 0.70 meters (Assessment 33552) The positive geochemical results continue to delineate the presence of gold mineralization in the area encompassing the Johan MINFILE occurrence. Further work on the DORT claims is warranted to constrain bedrock anomalies, and to provide direction for advancing exploration targets.

In 2013, Bernie Kreft conducted a program of soil and rock sampling in an effort to verify historical results. Results confirmed the presence of widespread highly anomalous gold values at the Mariposite Creek and the TF zones.
