The Round Mountain East occurrence is located approximately 4.7 kilometres northwest of the Lawyers mine (094E 066), about 280 kilometres north of Smithers. It is exposed on the eastern slopes of Round Mountain, about 2 kilometres south of the confluence of Moosehorn Creek and the Toodoggone River. The showing lies within the Omineca-Cassiar Mountains at the southern end of the Toodoggone Gold Camp.

The showing is situated within a Mesozoic volcanic arc assemblage which lies along the eastern margin of the Intermontane Belt, a northwest-trending belt of Paleozoic to Tertiary sediments, volcanics and intrusions bounded to the east by the Omineca Belt and to the west and southwest by the Sustut and Bowser basins. Permian Asitka Group crystalline limestones are the oldest rocks exposed in the region. They are commonly in thrust contact with Upper Triassic Takla Group andesite flows and pyroclastic rocks. These Takla rocks have been intruded by plutons and other bodies of the mainly granodiorite to quartz monzonite Early Jurassic Black Lake Suite and are in turn unconformably overlain by or faulted against Lower Jurassic calcalkaline volcanics of the Toodoggone Formation (Hazelton Group).

The dominant structures in the area are steeply dipping faults which define a prominent regional northwest structural fabric trending 140 to 170 degrees. In turn, high angle northeast-striking faults (approximately 060 degrees) appear to truncate and displace northwest-striking faults. Collectively these faults form a boundary for variably rotated and tilted blocks underlain by monoclinal strata.

Round Mountain is underlain mostly by greenish andesite porphyry and volcanic conglomerate but hostrocks have relict textures of argillic-altered porphyritic trachyandesite flows and tuffs, part of a larger package of Toodoggone Formation volcanics assigned to the Metsantan Member. Other lithologies of the Metsantan Member include mostly latite lava flows with interflow lahar, and mixed epiclastic and pyroclastic rocks (Bulletin 86). These rocks are cut by the Cliff Creek fault, along which the showing lies.

The Round Mountain East showing consists of a zone of argillic alteration and silicification with minor quartz veining and strikes about 335 degrees. The zone is believed to be an extension of the Cliff Creek zone at the nearby Lawyers mine (094E 066). Clays and sericite replacing feldspars and mafic minerals, goethite replacing pyrite veinlets, and limonite staining comprise argillic alteration within this zone. A few areas of silicification, consisting of quartz and clays, occur within this zone of argillic alteration. The zone is about 200 metres long by 150 metres wide. Areas of strong argillic alteration with silicification continue 1800 metres on a bearing of 330 degrees where they crop out above the banks of the Toodoggone River.

Several rock samples were taken from, and adjacent to, this zone with assay results generally yielding only background values. One sample, however, did analyze 2.59 grams per tonne silver and 2.00 grams per tonne gold (Assessment Report 17299).

The Round Mountain showings and the Kodah showing (094E 068) were contained in the Louis property of Stealth Resources in the mid-2000s. Between 2003 and 2006, Stealth Minerals conducted mobile metal ion soil sampling and PIMA spectroscopy analysis on rocks in the Round Mountain East showings area. The mobile metal ion line was run to the immediate west of the Round Mountain West showing (094E 159) in 2006.

By 2014, these occurrences were contained within a claim block held by Phoenix Precious Metals Corp. as part of their Lawyers property (094E 066).

Refer to Moosehorn East (094E 261) for details of earlier work done, primarily by Cyprus Metals Canada on its GWP property.

In 2019 and 2020, Benchmark Metals Inc. completed programs of geochemical (rock and soil) and biogeochemical sampling, ground and airborne geophysical surveys, 242 diamond drill holes, totalling 69 080 metres, and 191 reverse-circulation drill holes, totalling 28 395 metres, on the area as part of the Lawyers property. The majority of the drilling targeted the Cliff Creek, Dukes Ridge, Phoenix and AGB zones of the Lawyers (MINFILE 094E 066) deposit.
