The Discovery B prospect is located in the south-central region of the Little Fort property (formerly known as the Silver Lake property), immediately south of Portage Lake in the southern portion of the Discovery 5 claim and several hundred metres north of the Spider showing (092P 181). The Little Fort property lies approximately 20 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 Discovery showings are high-grade quartz-sulphide veins with localized high copper values plus silver and minor gold. Patchy chalcopyrite and pyrite occur in quartz-calcite veins that cut magnetite-, pyrite- and chlorite-altered Nicola Group mafic volcanics. Sulphides are fine- to locally medium-grained and crudely banded with coarser grained chalcopyrite forming fracture veinlets in the surrounding rock (Assessment Report 26457).

The new discoveries, two areas of massive sulphide float located approximately 1 kilometre apart, were first identified by P. Watt while prospecting in 2000. Christopher James Gold Corporation followed up the discovery with a preliminary exploration program of soil geochemistry, geological prospecting and geophysical surveys. Coincident northwest-trending copper soil and very low-frequency electromagnetic (VLF-EM) anomalies were identified between Discovery A and Discovery B. Exploration continued in 2001 with a limited trenching and drilling program and geochemical and geophysical surveys. A high-grade copper (silver±gold) massive sulphide quartz vein zone was discovered downslope of Discovery A. Soil sampling of the vein zone returned anomalous values for copper and silver (Assessment Report 26839B). Trenching revealed a 1-metre-wide zone of massive chalcopyrite, pyrite and patchy quartz at least 25 metres long. Phase one drilling focused on testing the geometry of the anomalous zone west of Discovery A. Six NQ-size diamond drillholes totalling 548.43 metres were completed. Three holes returned good results for copper and silver, including 5.37 metres averaging 1.76 per cent copper and 11.23 grams per tonne silver (Assessment Report 26839B). Analysis of mineralized zones in the core indicated a southeast trend to the mineralization. A second phase eight-hole NQ-size diamond drill program totalling 934.52 metres focused on the northwest-trending anomaly identified in previous geochemical and geophysical surveys and resulted in the discovery of an area of high-grade mineralization identical to Discovery A, located approximately 600 metres west of Discovery A.

No further work was completed until 2007, when Christopher James Gold Corporation conducted an airborne geophysical survey of the entire Little Fort property. In 2008, a property-wide trenching program was undertaken. Five trenches were excavated on the Discovery prospects, but three were abandoned. Results from the two completed trenches failed to prove continuation of the Discovery showings. The property was later acquired by Jiulian Resources Ltd. from Gunpoint Exploration Ltd. (formerly known as Christopher James Gold Corporation).
