Rocks mapped on the Molly Gibson property fall into two main categories: 1) interbedded limestone, siltstone, tuff, and andesitic to latitic volcaniclastic and volcanic rocks (all exhibiting some degree of metamorphism), and 2) intrusions ranging from massive bodies of monzonite to dikes and sills of monzonite and syenite porphyry. The stratified rock occur over most of the property. Dikes, sills, and possibly small plugs or apophyses of the intrusive rocks occur in several areas within the sedimentary formation. In the southeast part of the property, massive porphyritic monzonite. The layered rocks are part of the Carboniferous to Permian Mount Roberts Formation and the intrusions are probably part of the Eocene Coryell Plutonic Suite.

Lithologies within the sedimentary/volcanic package include the following: 1) limestone - thin to thick bedded, light to dark grey in color, varies from fairly massive and clean to laminated and gritty/tuffaceous, recrystallized from fine to medium grained, 2) siltstone - thin to medium bedded, tan, dark brown, light to dark grey (argillaceous) colour, probably tuffaceous, extensively altered to hornfels, 3) tuff - thin to medium bedded, pale grey colour, fine grained, dense and siliceous (hornfels/silicified), 4) volcanics - dull greenish to brown, fine grained, conformable to bedding, some vesicular (probably representing flows although sills are probably also present), some clastic texture with lapilli-size fragments compositionally similar to the matrix, commonly biotitic. Intrusive lithologies include fine to coarse-grained monzonite and syenite. The syenite occurs as porphyritic/aphanitic dikes or sills within the Mount. Roberts Formation. The monzonite includes a massive, medium to coarse grained porphyritic/phaneritic. biotite-rich phase constituting the northern edge of a large pluton of Coryell Syenite that lies mostly south of McRae Creek. Small bodies of medium grained, equigranular to porphyritic/phaneritic monzonite intrude the Mount Roberts Formation. These intrusions may be small plugs or simply large sills/dikes. Additionally, sills of a fine grained biotite porphyry (monzonitic to syenitic composition) are very common within the Mount Roberts Formation.

Stratigraphy of the sedimentary/volcanic package generally strikes northwest and dips east. Local variations are common, especially within thinly bedded carbonate units where very ductile deformation is evidenced by strongly contorted bedding. Fine-grained biotite (macroscopic) is developed in the clastic and volcanic units in the area directly south and west of the old workings. The biotite imparts a distinct schistosity which generally strikes northeast and dips vertically (crosscutting stratigraphy). These schistose zones are only 5-20 metres wide in the area south of the workings, along the ridge crest; they appear to grade into hornfels or volcanic units lacking directional fabric. West of the workings, down the ridgetop, the biotite becomes coarser grained, the schistosity more distinct and some amphibolite occurs.

Alteration on the Molly Gibson property is probably most prominently displayed in the hornfels. The siltstone protolith is altered to a dense, siliceous assemblage that probably includes microcrystalline quartz, biotite, potassium feldspar, and diopside. Original compositional banding is well preserved in the hornfels. Additionally, crosscutting selvages of probable potassium feldspar and diopside replacing biotite hornfels represents a prograde metasomatic alteration assemblage. Small areas of garnet-diopside skarn are found within carbonate beds near intrusive contacts. This skarn was not observed to demonstrate crosscutting relations with any other rock.

Historic production from the Molly Gibson was from massive to stringer zones of pyrite and pyrrhotite that occur along and near a contact between limestone and hornfels (possibly very fine-grained skarn). Porphyritic/aphanitic syenite dikes are present at the collars of several workings: their significance in ore localization is unknown, but seems likely. Sulphides on the dumps occur as stringers and bands of disseminated grains, principally in hornfels. These sulphides include pyrrhotite > pyrite >> chalcopyrite. The pyrrhotite is moderately magnetic. Greyish white vein quartz occurs with some of the sulphides. Disseminated pyrite and pyrrhotite are common in hornfels, tuff, and metavolcanics in other parts of the property, typically in only trace amounts. Volcanic beds host poddy, more massive pyrrhotite zones as well as disseminated sulphide. These more massive zones are only 1-5 square metres in exposure, and are located in the southeastern portion of the property.

The property is located at the 1524-metre elevation on the north side of McRae Creek, 1.6 kilometres west of Coryell. The original claims, the Irish Nellie, Mollie Gibson, Grey Eagle, Manchuria and Mollie Gibson Fraction (Lots 595s-599s, respectively) were located in 1905-06. Additional claims ‘Singer property’ were added in 1933 and 1936. Shipments were made from the property as early as 1908; these were probably from the surface on the site of the inclined shaft. Molly Gibson Burnt Basin Mining Company, Limited, was incorporated in September 1916 by Samuel Irving, J.B. Singer, L. Schwartzenhauer and associates, reportedly to acquire the property from the Paulson Brothers. Exploration and development work continued into 1930. A crosscut, probably the beginning of the Purcell adit, was commenced in 1917, the object being to tap the inclined shaft. By 1919 this had been advanced 81 metres, and from the shaft a short drift had been driven on the ore; by 1922 the shaft was down 26 metres. During all this time some surface exploration was also done. After 1922 little development work appears to have been done until 1933 when a two year lease on the property was given to Oscar Andeson and associates of Rossland. Ore was shipped in 1933 and 1934 from the vicinity of the shaft. Fountain Oils, Limited, of Calgary, acquired the property in 1935; the company name was changed to Molly Gibson Mines Limited in June 1935. Work on the property began in the fall of 1935. In 1936, the Purcell adit comprised 94 metres of drifts and crosscuts. Two short adits, the ‘Twin Tunnels’, 8.5 and 10.4 metres, respectively, in length, were driven from an opencut. A new low level adit, the Singer, was begun in 1936 at a point 47 metres below and 122 metres north of the shaft. During 1937, 59 metres of drifting and 96 metres of crosscutting was done in the Purcell adit. In 1938, a further 14 metres of drifting, 93 metres of crosscuts and 25 metres of raising was carried out; 20 tonnes of ore were shipped during the year. Mr. F. Singer shipped ore in 1940.

Exploration within the past twenty years includes a VLF-EM survey and limited mining organized in 1974 by Herman Hoehn and Stan Ruzika, both prospectors from Grand Forks. In 1983, a short geologic mapping and sampling program was conducted by M. Fox, a geologist from Calgary, Alberta. In 1987 and 1988 an extensive program including soil geochemistry, geologic mapping, VLF-EM, magnetic, and induced polarization surveys was conducted under the supervision of Lawrence Sookochoff, P. Eng., of Vancouver, for Mollie Gibson Mines, Inc. A diamond drilling program was conducted subsequently: no report of this program has been located. Drill collars and core have been located at four sites near the top of the old surface and underground workings. During September and October, 1991, Pan Orvana Resources, Inc. conducted a program of geologic mapping and rock and soil geochemical sampling/analysis. In 1994, an exploration program was conducted by R.E. Miller on behalf of Herman Hoehn and consisted of 4 kilometres of road clearing and rehabilitation, adit maintenance, and 1.5 kilometres of chain and compass line along which 30 rock chip samples were collected. Newport Gold Inc. acquired the Burnt Basin property in 2003, primarily as a gold exploration property. A short program of prospecting, geological mapping and rock sampling was completed on the property during June 2004.

In 2006, samples of mineralized quartz vein material from the Purcell adit and Inclined shaft yielded values of up to 13.7 grams per tonne gold, while samples from the Upper adit and the Twin tunnels, located approximately 200 and 300 metres to the south, respectively, assayed 16.0 and 29.5 grams per tonne gold, respectively (MacIntyre, D. (2018-11-26): Technical Report - Molly Gibson Lode Property). Also at this time, samples from the Lime and Magnetic open-cuts, located approximately 50 metres north of the Twin tunnels, yielded 26.1 and 17.8 grams per tonne gold, respectively (MacIntyre, D. (2018-11-26): Technical Report - Molly Gibson Lode Property).

In 2007, Newport Gold Inc. conducted a work program on the Burnt Basin property. Three significant new discoveries in outcrop included the Gold Knoll, Unexpected and Ajax showings. At the Gold Knoll showing, results of 43.07 and 42.78 grams per tonne gold were returned from narrow quartz veins. Several areas of mineralization were discovered at the Unexpected showing, with results of 33.99 grams per tonne gold from narrow quartz veins and 51.5 per cent lead from massive galena. At the Ajax showing, values of 15.4 and 5.31 per cent zinc were returned from grab samples of massive sphalerite-magnetite in outcrop (Assessment Report 29724).

In 2011, Newport conducted geological reconnaissance at the Molly Gibson mine, including the collection of 68 rock samples. Highlights included samples 11CAP030 and 11CAP031, which returned 20.4 and 8.67 grams per tonne gold, respectively (N MINER, May 25, 2012).

In 2018, Rich River Resources, on the behalf of Golden Lake Exploration Inc., completed a program of prospecting and geochemical (rock, soil and silt) sampling on the area as the Molly Gibson-Golden Lode property. Five samples (32164 to 32168) from the Molly Gibson workings area yielded values from 7.08 to 59.80 grams per tonne gold (MacIntyre, D. (2018-11-26): Technical Report - Molly Gibson Lode Property).
