The Jupiter molybdenum-copper occurrence is located 15 kilometres south of New Hazelton in the Rocher Deboule Range. In 1982, the occurrence was held as part of the Schemo property by Pharaoh Exploration (see the Sultana occurrence (093M 061) for more information).

The area is underlain by porphyritic granodiorite of the Late Cretaceous Rocher Deboule stock which is part of the Bulkley Plutonic Suite. The stock has been dated at 72 million years from potassium/argon dating of biotite (Geological Survey of Canada Open File 2322).

A molybdenum-copper occurrence is shown on Map 69-1 but no other information is available. It is assumed to be porphyry-style disseminated molybdenite-chalcopyrite mineralization.

In 2008, according to Duncastle Gold, several samples were taken in the Slate Creek (Jupiter area). Float Sample 23178 (about 400 metres west of the MINFILE plotted Jupiter location) assayed 0.27 per cent copper, 0.72 per cent lead, 9.01 per cent zinc and 115 grams per tonne silver; gold was only 0.01 gram per tonne (Assessment Report 30431). Another sample consisting of silicified argillite with 30 per cent fine-grained pyrrhotite, located about 800 metres west of the plotted Jupiter location, assayed 0.06 per cent copper, 0.3 per cent zinc and 1.5 grams per tonne silver (Assessment Report 30431).

Work History

In 2007, Crucible Resources Ltd. completed an option on the Brunswick (093M 066) and Jupiter from D. Warkentin. Two chip samples were taken in the Brunswick area and one float and two stream samples were collected in the Jupiter area (Assessment Report 29082).

In 2008, Duncastle Gold Corp. collected 51 rock and 53 silt samples in the Brunswick, Jupiter, Armagosa (093M 068) and Brian Boru (093M 064) areas (Assessment Report 30431).

In 2010, Dunham Gold Corp. completed a 495 kilometre airborne geophysical survey on its Porphyry Creek property which covered numerous showings including the Jupiter showing area (Assessment Report 31728).

The Porphyry Creek project consists of 13 mineral claims covering an area of 4811 hectares (ca. 2017). The claims overlap a small group of Crown-granted claims that surround the past-producing Red Rose tungsten mine (093M 067) and it is assumed that this area is fully excluded from the property.

The Porphyry Creek property contains eight separate MINFILE occurrences listed as: Armagosa (093M 068), Balsam (093M 059), Big Thing (093M 062), Brian Boru (093M 064), Brunswick (093M 066), Jupiter (093M 065), Sultana (093M 061), and Tina (093M 060). The Brunswick mine had some minor production from two adits driven to 20 and 52 metres, respectively and possibly from open cuts, prior to 1950. Development occurred mainly in the 1920s, and the total amount of ore produced is unknown, but ‘thirty bags’ of handpicked ore are reported from a later operator in 1954. Other occurrences that are reported to have some old development workings include the Armagosa and the Brian Boru, consisting of small open cuts and short adits. The Sultana prospect has had more extensive past exploration, including substantial trenching (essentially small-scale mining) and limited drilling on a high grade silver vein. This prospect was the main focus of an exploration and drilling program in 2010 and 2011 that identified extensive low grade copper and molybdenum mineralization below and to the northwest of the historical workings.

In 2018, Lansdown Holdings completed a minor program of prospecting and soil and rock sampling on the area.
