The June (Bug) showing is located just south of the Thompson River on Gladwin Creek, approximately 6.5 kilometres east-northeast of Lytton, and at an elevation of approximately 300 metres.

Regionally, The Mount Lytton Complex varies in age from Permian to Triassic. It is contained by Cretaceous formations of the Spences Bridge and Jackass groups.

The area is underlain by Triassic Mount Lytton Complex intrusives comprising dioritic and layered quartz-feldspathic rocks, mylonite and amphibolite.

Locally, gold is reported to have been found in an 80 metre adit tunnelled into white, glassy quartz in an altered volcanic formation close to a granitic contact and intersected by a series of quartz felsite dikes (Bulletin 1 (1932), pp. 70, 71). Faulting and fracturing is common in the area, with extensive quartz and disseminated pyrite.

A report on the area from the early 1930s indicated the presence of gold in the aforementioned adit. Early follow-up investigations proved unsuccessful in locating the entrance to the old adit, until it was found upon scaling an adjacent mountain slope. This site was deemed dangerous to traverse and cannot be accessed without climbing gear. Prospecting in the area in 2008 resulted in the recovery of small, well-rounded, gold nuggets weighing 3.24 grams in total (Assessment Report 31069). In August 2010, reconnaissance prospecting was carried out over two corresponding traverses, with no significant rock exposures found. Further prospecting in 2011 resulted in the collection of several rock samples, which were found to contain visible pyrite within the quartz host rock. One of these samples showed specular particles of gold distributed within and bordering the sulphide when examined in thin section (Assessment Report 33204).
