The Worldstock porphyry showing is located in the southeast portion of the Little Fort/Silver Lake property, approximately 22 kilometres northwest of the town of Little Fort.
The property lies within the Quesnel Terrane and covers Upper Triassic Nicola Group volcanic and sedimentary with numerous intrusions. The area is strongly faulted with a general northwest strike. Intrusive rocks are predominantly Late Triassic to Early Jurassic diorites, gabbros, microdiorite, local syenites, and intrusion breccias.
The Worldstock showing is an isolated outcrop of iron carbonate-chlorite-pyrite-silica altered rock with traces of chalcopyrite. Drilling showed that the area is underlain by an extensive stockwork of vuggy quartz-carbonate-pyrite veinlets cutting altered Nicola Group mafic volcanics. High copper values and potassium feldspar alteration zones are commonly associated with rare, narrow crowded feldspar dikes. The showing was discovered during an exploration program by Christopher James Gold Corporation in 1997-98, that covered the Deer Lake (092P 010), PGR (092P 137) and the Crater and Woodstock claims (Assessment Reports 25503, 26180). Strongly altered volcanics of the Upper Triassic Nicola Group yielded 0.78 per cent copper from a 4 by 3 metre panel sample (Assessment Report 25503). The showing is located along or near the contact between pyroxene porphyry and breccia of the volcanic member of Nicola Group, and overlying conglomerate of the mixed sedimentary-volcanic unit (uTrNsv; Fieldwork 2000), although the actual protolith to the altered rock is uncertain. Altered dioritic intrusions occur in nearby outcrops (Press Release - Christopher James Gold Corporation, 1998). A pyrite-silica altered rock exposed about 800 metres to the northwest, however, appears to have been derived from a feldspar phyric intrusive rock, consistent with the suggestion that the Worldstock showing may represent part of a porphyry system.
Staking of the Worldstock claim followed the discovery of the showing in 1997 by prospector Paul Watt. Christopher James Gold Corporation conducted a soil geochemical survey in 1999. The B.C. Geological Survey conducted a regional till geochemistry program over NTS mapsheets 092P09W and 08W in 1999 (Open File 2000-17). From 2000 to 2001, Christopher James Gold Corporation carried out additional geochemical and geophysical surveys on the property. Anomalous zones were identified and further geological, prospecting, and detailed soil surveys were performed to define targets within the anomalous area. It was determined that the main copper soil/induced polarization anomaly featured porphyry-style alteration, extensive pyrite and local chalcopyrite mineralization. Seven drillholes, totalling 888.19 metres in depth, were completed between June and July 2001. The drill holes returned several significant copper (silver) intersections, including a 10.4 metre section averaging 0.38 percent copper and 2.6 grams per tonne silver (Assessment Report 26839). Strongly anomalous copper values in the drillcore were associated with pyritic-propylitic, argillic-phyllic and potassic alteration zones. In 2007 and 2008, an airborne magnetic-electromagnetic geophysical survey was conducted over the entire Little Fort property.
In 2011, Jiulian Resources Limited purchased the property from Gunpoint Exploration Limited, formerly Christopher James Gold Corporation. A stream sediment and silt sampling program carried out by Jiulian Resources Limited in 2012 confirmed known anomalies around mineral showings and prospects and identified a broad intensive copper-gold anomaly around the Worldstock showing. An induced polarization geophysical survey was carried out to follow up on the geochemical survey results.
