The AMPLE (Lot 335) prospect is located on the north side of Cayoosh Creek, approximately 1 kilometre northwest of the confluence of Phair Creek. The town of Lillooet, British Columbia, lies 9 kilometres to the northeast.

Regionally, the area is underlain by sedimentary rocks of the Lower Cretaceous Brew Group, part of the Jurassic to Cretaceous Cayoosh Assemblage, and marine sedimentary and volcanic rocks of the Mississippian to Jurassic Bridge River Complex. A shear zone, thought to be related to a regional thrust fault (Cayoosh Creek Thrust Fault), separates argillite and sandstone of the Jurassic to Cretaceous Cayoosh Assemblage from overlying Mississippian to Jurassic Bridge River Complex metasediments and schists. Mineralization along the Cayoosh Creek Fault can be traced for an approximately 3 kilometre length from the Ample-Goldmax prospect westward through the Ample Mine and Wedge showings to the Golden Cache Mine. The Bonanza prospect on the south side of Cayoosh Creek appears to part of the same system.

At the Ample adits, bedrock consists of phyllites, quartz-biotite-hornblende schists and quartzites, with the adits being driven along a zone of faulting in the schistose-phyllitic unit overlain by a more competent quartzite. The zone is 10 metres wide and has been traced for approximately 300 metres. Randomly orientated quartz veins, up to 0.3 metres wide, are hosted in the zone along with rotated and folded schists beds. Mineralization consists of pyrite, arsenopyrite, pyrrhotite and chalcopyrite occurring within the quartz and schistose material. Graphite, calcite, siderite and epsomite are also reported. Another zone of mineralization is reported on the Dave claims (Bonanza prospect), located at a similar elevation on the south side of Cayoosh Creek.

The Ample Mine was worked intermittently from the late 1800s to the 1930s, with approximately 300 metres of underground workings established and a few thousand tonnes of material mined. The Ample (L.335) occurrence was explored by three tunnels and an incline, for approximately 80 metres on the Gem claim (Lot 525 - forfeited February 6, 1991) between 1897 and 1905. The main portals are at an elevation of approximately 1132 metres. The work was done by either the Alpha-Bell Company or the Toronto-Lillooet Gold Reef Company. In 1905, the property was consolidated and one of the tunnels extended to 77 metres. In 1932, the showing was held by Lillooet and Cariboo Gold Fields Syndicate.

In 1974, samples from adits and talus reportedly assayed up to 9.6 grams per tonne gold, whereas select samples of sulphide material assayed greater than 34.2 grams per tonne gold (Property File - G.P.E. White [1975-02-19]: Letters Re: Ample Group).

In 1994 and 1995, a program of prospecting and soil sampling was completed. In 1995, a sample of ore material (mostly arsenopyrite) taken from the old mill site is reported to have yielded 25.03 grams per tonne gold (Assessment Report 23945). In 1996, nine diamond drill holes, totaling approximately 1800 metres, tested a 600 by 100 metre gold-in-soil anomaly. In 1997, Homestake Canada Inc. drilled 14 holes, totaling 2728 metres, on the Cougar zone. Drilling in 1998 brought drilling to 21 holes totaling 4200 metres. Gold-Ore Resources Limited optioned the property in 1998 and completed a nine-hole, 907-metre drill program in 1999. This work was primarily on the Ample-Goldmax zone approximately 1 kilometre to the east of the Ample mine.

In 1999, a 2.7-metre chip sample (141013) from the Ample mine area assayed 16.1 grams per tonne gold, whereas a 1.0-metre chip sample (141045 and 141046) from the no.3 adit assayed 9.2 grams per tonne gold (Property File - Gold-Ore Resources Ltd. [1999-12-23]: Report on the 1998 and 1999 Mineral Exploration Programs - Geology, Soil Geochemistry, Prospecting and Diamond Drilling - Ample/Goldmax Property).

In 2002, Quartz Mountain Resources optioned the Ample-Goldmax property. In 2004, Canadian Resources House acquired the property. In 2007 and 2008, Supreme Resources Ltd. conducted rock sampling and geological reviews on the property and focused drilling efforts on the Ample-Goldmax prospect area (Assessment Reports 29994, 30805). Drill hole AG-08-37 had an intercept of 6.09 metres grading 4.17 grams per tonne gold and drill hole AG-08-39 intersected a near surface 8.53 metres of indicated 5.91 grams per tonne gold.

From 2016 to 2019, owner C. Lynes and American Creek Resources Ltd. ran programs of geological mapping, prospecting and rock and soil sampling in the area, from the Ample mine eastward to the Ample-Goldmax prospect and across the highway to the Bonanza prospect (Assessment Reports 36394, 37718, 39236). In 2022, Stinger Resources Ltd. conducted a program of geological mapping, prospecting and soil sampling along the highway, in the Ample mine area and the Ample-Goldmax and Bonanza prospects (Assessment Report 40590).
