The August (August 30) occurrence is located in the southern end of the Toodoggone Gold Camp, between Attycelley and Kemess creeks, approximately 10 kilometres east of the northern end of Duncan Lake and about 188 kilometres north-northwest of the community of Germansen Landing.
The Toodoggone Gold Camp lies within the eastern margin of the Intermontane Belt and is underlain by a northwest trending belt of Paleozoic to Paleogene sediments, volcanics and intrusions. Regionally, the area is situated within a Mesozoic volcanic arc assemblage bounded to the east by the Omineca Belt and to the west and southwest by the Sustut and Bowser basins. Devonian to Permian Asitka Group crystalline limestones are the oldest rocks exposed in the region and are commonly in thrust contact with Upper Triassic Stuhini Group marine sedimentary and volcanic rocks, andesite flows and pyroclastic rocks. These units have been intruded by the granodiorite to quartz monzonite of the Early Jurassic Black Lake Suite and are in turn unconformably overlain by or faulted against dacitic volcanics and volcaniclastics of the Lower Jurassic Toodoggone Formation (Hazelton Group).
The dominant structures in the area are steeply dipping faults that define a prominent regional northwest structural fabric trending 140 to 170 degrees. 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. A major structural zone associated with the Saunders Creek regional fault cuts diagonally through the area, striking northwest.
The geology of the area is separated into four northwest trending, fault-bound panels. The occurrence is underlain by the west-central panel, an up-faulted panel of regionally propylitic altered Toodoggone volcanics in the south portion and Stuhini volcanics in the northern portion. A major north-northwest striking fault separates the hosting panel from structurally higher, zeolitized Toodoggone volcanics to the east. Stuhini Group volcanics are characterized by augite and plagioclase porphyry, basalt and andesite flows and breccias. Several members of the Toodoggone Formation are present. The Adoogacho Member, the lowest stratigraphic division, consists of reddish and mauve, variably welded ash flows and lapilli-ash tuffs with subordinate block-lapilli tuff, epiclastics and rare andesitic lava flows interbedded with ash-flow tuffs (Bulletin 86). These rocks are propylitically altered with argillic overprinting. The Moyez Member consists of grey to maroon conglomerates containing 20 to 30 per cent by volume granite clasts averaging 4 centimetres in diameter.
Locally, north to northwest trending faults and shears in quartz-sericite-calcite altered chloritic basalt and late aplite dikes contain oxidized quartz-carbonate veins, veinlets and breccia with associated pyrite, chalcopyrite, galena, sphalerite and tetrahedrite mineralization. The main zone veins have been exposed over a distance of 6 metres and are open in width and along strike. Similar mineralization is reported approximately 500 metres to the northeast of the main zone.
Another zone of mineralization is located approximately 300 metres to the south-southeast of the August 30 trenches and consists of andesitic volcanics hosting quartz-calcite veins with chalcopyrite and malachite.
In 1986, a float sample (MR-12) of malachite-stained tuff, taken from the ridge to the southwest, assayed 530.0 grams per tonne silver and 0.84 gram per tonne gold (Assessment Report 15184).
In 2003, three grab samples were obtained from the poorly exposed vein over a distance of 6 metres, with one of the samples yielding 25.48 grams per tonne gold and 29.3 grams per tonne silver from a grab of quartz-carbonate vein material (Assessment Report 27429). Approximately 200 metres northwest of the veined zone, a grab sample (133384) of talus containing pyritic quartz float and yielded 1.71 grams per tonne gold (Assessment Report 27429).
In 2004, a channel sample assayed 13.58 grams per tonne gold over 2.4 metres, whereas a rock sample (185693) of vein material yielded 0.15 per cent copper, 0.066 per cent tungsten, 636 grams per tonne silver, 8.80 grams per tonne gold and greater than 1.0 per cent each of lead and zinc (Assessment Report 27636).
In 2006, two chip samples (DK-GO6520 and DK-GO6518) from the eastern trench, which was dug across the August 30 veins, yielded values of 30 and 4.49 grams per tonne gold over 0.3 and 1.0 metre, respectively, whereas two other samples (DK-GO6520 and DK-GO6518) assayed 36.9 and 50.4 grams per tonne silver, respectively (Assessment Report 28649). Also at this time, a chip sample (GO6350) from the south-southeast zone assayed 2.56 per cent copper and 17.6 grams per tonne silver over 1.0 metre, whereas two chip samples from the northeast zone yielded from 0.36 to 0.39 per cent copper, 0.23 to 0.25 per cent lead, and 6.2 to 6.8 grams per tonne silver over 1.0 metre each, respectively (Assessment Report 28649).
In 2014, a rock sample (2691915) from the main zone assayed 0.19 gram per tonne gold, whereas samples (2691914 and 2691918) from the south-southeast and northeast zones yielded 0.402 and 0.611 per cent copper, trace and 0.423 per cent lead, and trace and 0.264 per cent zinc with 4.9 and 7.0 grams per tonne silver, respectively (Assessment Report 34942).
The area has been explored in conjunction with the nearby Mess showing (094E 070) located 2 kilometres southwest, since the early 1980s.
In 1980 and 1981, Serem Ltd. completed program of geological mapping and rock, soil and silt sampling on the area as the Mess 1-4 claims. In 1986, Western Premium Resource Corp. completed a program of geochemical (heavy mineral, rock, silt and soil) sampling and an airborne geophysical survey on the area.
During 2003 through 2006, Stealth Minerals Ltd. completed programs of prospecting, geochemical (rock, silt and soil) sampling and geological mapping in the area as the Fog-Mess property.
During 2014 through 2017, Serengeti Resources Inc. completed programs of prospecting, rock, silt and soil sampling and a 9.0 line kilometre induced polarization survey on the area as the UDS property.
