The Kem 6 occurrence is located on an east-facing slope at the southern end of the Toodoggone Gold Camp, approximately 1.5 kilometres south of Attycelley Creek and 3.5 kilometres east of the north end of Duncan Lake, about 250 kilometres north of the community of Smithers.
The Toodoggone district 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 covering an area of 90 by 25 kilometres. The basement rocks are Proterozoic metasedimentary equivalents of the Hadrynian Ingenika Group. These rocks are unconformably overlain by volcanic and sedimentary units of the Devonian to Permian Asitka Group, which are in turn overlain by Upper Triassic basaltic to andesitic flows, volcaniclastics and minor limestone of the Stuhini Group. Volcaniclastic rocks of the Lower Jurassic Hazelton Group and rhyolitic to dacitic flows, intrusions and volcaniclastics of the Lower Jurassic Toodoggone Formation (Hazelton Group) overlie the Stuhini Group. Further to the west, nonmarine sediments of the Cretaceous Sustut Group overlie the volcanic strata and form the western margin of the district.
The Early Jurassic Black Lake Suite, of quartz monzonitic to granodioritic composition, has intruded the older strata in the central and eastern parts of the region and forms the eastern margin of the Toodoggone district. Within the district, syenomonzonitic and quartz feldspar porphyritic dikes may be feeders to the Toodoggone Formation.
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.
Locally, the area is underlain by augite porphyry basalt, dacite and andesite crystal and lapilli tuffs and flows, and augite crystal tuffs and ash tuffs of the Stuhini Group. To the northeast and east lie dacite lapilli and crystal tuffs and breccias, and andesite crystal tuffs of the Toodoggone Formation, which are interbedded with conglomerate, sandstone and siltstone. The Early Jurassic Kemess pluton, a monzonite intrusive body that is part of the Black Lake Suite, outcrops to the south.
The main zone of mineralization is hosted by east- to southeast-trending, south dipping fractures and occurs as two sharply defined, podiform or lensoid quartz-carbonate veins: vein A and vein B. These veins exhibit displacement up to 25 metres along later northwest-striking faults.
Vein A can be traced for approximately 150 metres along surface along its controlling structures in augite porphyry basalt and volcaniclastic tuffs of the Stuhini Group. The vein strikes 110 degrees, dips 50 to 70 degrees east and ranges from 0.2 to 4 metres wide with an average width of 1 metre. The northern end of the vein is terminated by a younger fault. Quartz, calcite, hematite, magnetite, pyrite and chalcopyrite comprise the mineralogy. Wallrocks are slightly propylitized. Stringers of quartz, hematite, magnetite, chalcopyrite and pyrite occur in patches along the contacts of the vein.
Vein B occurs 100 metres east of vein A. The vein ranges in width from 1.5 to 4 metres, strikes 085 to 090 degrees and dips approximately 60 degrees south. The vein occupies an earlier fracture in host dacite and andesite crystal and lapilli tuffs and flows of the Stuhini Group. It is composed of quartz with 5 to 25 per cent pyrite, 5 per cent hematite and trace chalcopyrite. Contact with chloritic wallrocks is sharp. Minor stringers of quartz, carbonate and sulphides are locally present in the host wallrock. The vein is crosscut by later faults and shear zones up to 0.1 metre wide.
Other zones of mineralization include silicified gossanous zones and quartz veins with associated galena, sphalerite, chalcopyrite and pyrite, and are located approximately 350 metres northwest, 400 metres north-northeast, and 400 metres southeast of the main vein zone (A and B veins).
In 1981, sampling of the main veined zone (A and B veins) yielded up to 4.90 per cent copper, 846.9 grams per tonne silver and 28.46 grams per tonne gold (samples 56252 and 70570; Assessment Report 10113). Also at this time, sampling of the other mineralized zones yielded up to 9.9 per cent copper, 0.27 per cent zinc, 240.0 grams per tonne silver and 1.21 grams per tonne gold from the northwest zone (samples 56340 and 56343), whereas samples (61300 and 56266) from the northeast and southeast zones yielded 0.24 and 0.47 gram per tonne gold with 122.4 and 36.0 grams per tonne silver, respectively (Assessment Report 10113).
In 1982, three trenches were dug across vein A. Sampling was conducted over standard panel areas of the trenches. Assay results from panel 211, trench 1, were 4.24 per cent copper, 29.95 grams per tonne silver, 0.80 per cent lead, 0.20 per cent zinc and 0.442 gram per tonne gold, whereas grab samples yielded up to 3.60 grams per tonne gold, 620.0 grams per tonne silver, 1.90 per cent copper, 0.12 per cent lead and 1.23 per cent zinc (Assessment Report 10742). Sampling of vein B yielded up to 30.0 grams per tonne silver and 0.43 per cent copper (Assessment Report 10742).
In 1998, two rock samples (AJB-6 and -8), taken approximately 400 metres to the southeast of vein A , yielded up to 1.00 per cent copper, 100.0 grams per tonne silver and 5.93 grams per tonne gold (Assessment Report 25722).
In 2000, a rock sample (JJA-8) from a 1-metre-wide shear with an oxidized massive sulphide vein assayed 0.32 gram per tonne gold and 12.8 grams per tonne silver, whereas a nearby float sample (JJA-7) yielded 15.60 grams per tonne gold, greater than 100 grams per tonne silver and 0.659 per cent copper (Assessment Report 26360). Also at this time, a rock sample (JJA-5) taken approximately 400 metres to the southeast assayed 4.60 grams per tonne gold, 10.2 grams per tonne silver and 0.271 per cent copper, whereas three samples (ATTY-RB00-13 to -15), taken up slope to the east, yielded up to 0.56 gram per tonne gold, 33.6 grams per tonne silver, 0.242 per cent copper, 0.190 per cent lead and greater than 1.00 per cent zinc (Assessment Report 26360).
The area was originally staked by D.W. Chisholm in 1929 as the Fokker mineral claim.
During 1969 through 1973, Kennco Explorations Ltd. completed programs of prospecting and soil sampling on the area as the Attycelley 1-6 claims. In 1977, Bishop Mines Ltd. completed a program of rock and soil sampling and a 2.0 line kilometre ground magnetic and electromagnetic survey on the area as the Audrey property.
In 1980, ABM Mining Corp. completed a 69.8 line kilometre airborne magnetic and electromagnetic survey on the area as the Audrey 1, 2, East and West claims and Kem 1-9 claims. Also at this time, Inca Resources Inc. completed a program of soil sampling and a ground electromagnetic survey on the claims. In 1981, Texasgulf Inc. completed a program of geological mapping and rock sampling on the Audrey and Kem claims on behalf of Inca Resources. In 1982, Kidd Creek Mines Ltd. completed a program of geological mapping, trenching and rock sampling.
During 1990 through 1999, Electrum Resource Corp. conducted programs of prospecting, geochemical (rock, silt and soil) sampling, geological mapping and a 4.7 line kilometre ground magnetic and electromagnetic (VLF) survey on the area as the At 1-2 and Atty 3-7 claims.

During 2013 through 2016, Finlay Minerals conducted further programs of prospecting, geochemical (rock and soil) sampling and a LiDAR survey on the Atty property. In March of 2018, Serengeti Resources Inc. signed an option agreement to acquire a 100% interest in the Atty and ATG properties from Finlay Minerals Ltd. and Electrum Resource Corp., respectively. In 2018, Serengeti Resources Inc. conducted a program of rock sampling, core re-logging and sampling, geological mapping and a 20.0 line kilometre ground induced polarization survey on the area as the ATTY-ATG property. The property covers eight occurrences: Attycelley (094E 022), Awesome (094E 081), Fog 1 (094E 115), Fog 2 (094E 116), Fog 3 (094E 117), Kem 6 (094E 119), New Mess 1 (094E 120), and Wrich 1 (094E 122). During the months of June, July and August 2019, Serengeti conducted a broad exploration program on the ATTY property in order to follow up on drill core re-logging and sampling, mapping and geophysics completed in 2018. The 2019 program included 30.8 line kilometres of ground-based IP surveys in two phases and a diamond drilling program of 2318 metres in six drillholes.
