The STEVE'S occurrence is located 5.6 kilometres southeast of the summit of Alberts Hump, south of Abesti Creek and 3.6 kilometres southeast of the BV (094E 099), approximately 300 kilometres north of Smithers. It lies within the Omineca-Cassiar Mountains in the west-central portion of the Toodoggone Gold Camp.

The Steve's prospect 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. Takla volcanics have been intruded by the granodiorite to quartz monzonite Black Lake Suite of Early Jurassic age 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.

The Adoogacho and Metsantan members of the Toodoggone Formation underlie the AL property. The Adoogacho Member consists of trachydacite ash-flow tuff with lenses of lapilli tuff, rare marlstone and conglomerate near the base. The Metsantan Member is composed mainly of trachyandesite (latite) flows with lenses of lapilli tuff, and lahar; minor volcanic sandstone and conglomerate (Bulletin 86). The Metsantan Member, in part, directly overlies the basal Adoogacho Member and is also in fault contact with it. For a more detailed account of the local geology and alteration refer to the Bonanza occurrence (094E 079).

The Steve's prospect consists of a large (400 metres long by 300 metres wide) alteration system, roughly ovoid in shape. The zone has a silicified core with a large envelope of advanced argillic alteration, similar to the Patti prospect (094E 101) located 1.1 kilometres southwest. The silicified core comprises three (possibly four) separate siliceous outcrops with different fracture patterns, textures, and mineralogy. They are separated by zones of argillic or argillic-silicic alteration. Accessory minerals in the silicified core include limonite, barite and rare hematite, sericite, and clays. Barite is common in the southeastern section of the core zone where it occurs as breccia matrix and as massive veins up to 15 centimetres wide.

In 1983, sample G-126, a 1.0-metre chip sample from a barite-rich breccia zone near the southeast corner of the prospect assayed 2.08 grams per tonne gold (Assessment Report 14460).

In 1985, Energex Minerals Ltd. carried out geological mapping and rock geochemical sampling on the Steve’s showing.

In 2007, Christopher James Gold Corp. completed a helicopter-borne magnetic gradiometer survey consisting of 2229 line-kilometres over all historic gold deposits and MINFILE occurrences on the property, including the Steve's area. Maps completed include coloured Total Magnetic Intensity, Measured 3-D Analytic Signal, Measured Vertical Magnetic Gradient, and colour-shaded Tilt Derivative of the Total Magnetic Intensity.

From 2020 through 2023, Thesis Gold Inc. completed programs of prospecting, mapping, geochemical (rock and soil) sampling, ground and airborne geophysical surveys, re-logging/re-sampling of historical drill core, and extensive digitization and compilation of existing exploration data on their Ranch property. From 2021 to 2023, 368 diamond drill holes, totaling 68,481.6 metres were completed on the Ranch property, with the majority of the drilling targeting the major prospects of Bonanza, Ridge, Bingo, Thesis II, Thesis III, BV, JK and Eric. Metallurgical testing and environmental monitoring/baseline and geotechnical studies and infrastructure upgrading were also initiated during this period, along with First Nations consultations. Drilling at the major prospects on the Ranch property expanded the known mineralized zones along strike and at depth.

A large northwest-trending alteration body at the Steve's occurrence was more accurately defined by field mapping in 2021. In 2022 and 2023, 8 diamond drill holes were completed for a total of 2,529 metres. 2022 drilling at Steve's encountered good alteration and gold grades, including a 119.2 metre intercept grading 0.97 gram per tonne gold and 1.06 grams per tonne silver from 356.8 to 476 metres downhole in drill hole 22STVDD001. There are multiple higher-grade sections within this deeper mineralized intercept. For example the 1 metre interval from 460 to 461 metres graded 10.35 grams per tonne gold and 1.82 grams per tonne silver.

Drilling in 2023 extended the mineralization zone at Steve's to a 330 metre strike length and demonstrated continuity at depth. Highlights from the 2023 drilling program include drill hole 23STVDD003, which intersected near surface mineralization assaying 1.96 grams per tonne gold and 5.26 grams per tonne silver over 16.35 metres, including 7.06 grams per tonne gold and 19.39 grams per tonne silver over 3 metres (Assessment Report 41940).

In August 2023, Benchmark Metals Inc. merged with Thesis Gold Inc., joining the Lawyer Project, located in similar Toodoggone Formation rocks to the southeast, with Thesis Gold's Ranch Project.

A NI 43-101 & 43-101F1 Technical Report and Updated Mineral Reserve Estimate of the Lawyer-Ranch Gold-Silver Project was prepared for Thesis Gold Inc. by P & E Mining Consultants Inc. in May 2024 and an updated Preliminary Economic Assessment (PEA) was completed for the Lawyers-Ranch Project by JDS Energy & Mining Inc. effective August 30, 2024.

In 2024, drilling at the Ranch property was designed to advance engineering and environmental baseline studies in preparation for a Prefeasibility Study led by Ausenco Engineering Canada ULC and Mining Plus Canada Consulting Ltd. with 2,226 metres of drilling focused on geotechnical and hydrogeological studies (Thesis Gold Inc. Press Release Feb. 18, 2025).

See Bonanza (094E 079) for details of the Ranch (Al) property which presently (2025) contains the Steve's occurrence, as well as other prospects.
