The Slide occurrence lies near the northeastern margin of the Duckling Creek Complex, on the north side of Haha Creek, about 59 kilometres northwest of the community of Germansen Landing.

The showing area is underlain predominantly by a mafic K-feldspar megacrystic phase of the Early Jurassic Duckling Creek Complex separated from monzonite and quartz monzonite of the Triassic to Cretaceous Hogem Plutonic Suite to the northwest across a series of steep northwest-trending faults. Along the bounding fault, on the eastern side of the area, an orange K-feldspar syenite phase intrudes both the K-feldspar megacrystic unit as well as Hogem monzonite on either side of the faulted boundary. There are also hints of Upper Triassic Takla Group volcanic rocks in the area of the Slide showings. Rocks here are intensely altered and bounded by the K-feldspar megacrystic unit, but show relict volcanic breccia textures, possibly rafts of strongly altered Takla volcanic rocks within the Duckling Intrusive Complex.

Alteration is more regionally manifested in the Slide area as K-feldspar and quartz veins overprinting selective-pervasive biotite alteration. Towards the faulted boundary with the Hogem rocks, associated with the orange syenite unit, strong pink K-feldspar plus white mica alteration is dominant.

Alteration is most intense in the immediate area of the Slide trenches with fine grained, sugary K-feldspar plus biotite plus magnetite plus chalcopyrite with veins of biotite and K-feldspar to 1 centimetre wide. Later stage pink K-feldspar plus/minus white mica washes over the earlier alteration and also cuts across the early foliation in veins. Northwest trending alteration boundaries are relatively sharp over 2-3 metres from weakly K-feldspar plus biotite-altered rock to intense, sugary grey K-feldspar-altered rock. There is a garnet halo to the intense alteration, prismatic, dark brown garnet occurs within approximately 20 metres of the alteration boundary.

Mineralization at Slide is almost exclusively limited to the intensely altered northwest-trending domains in the area of the Slide trenches. Fine grained disseminated chalcopyrite and bornite occur within a fine grained sugary K-feldspar plus biotite rock. Chalcocite and a distinctive pale blue azurite occur on fractures. Quartz veins containing blebby chalcopyrite occur to the west of the peak at the top of the Slide showing area. The veins are 1-2 centimetres wide and contain mineralization only locally.

In 2006, Teck Cominco conducted induced polarization (IP) geophysical surveys that outlined a 1.5 kilometre long chargeability anomaly that is open to the northwest and southeast. New copper-gold-silver mineralization has been intersected in two drillholes spaced 1000 metres apart testing the extents of surface mineralization and IP chargeability anomalies. Hole JTM06-07 intersected 0.72 per cent copper over a core width of 55.5 metres and hole JTM06-10 intersected 0.64 per cent copper, 0.15 gram per tonne gold and 30.0 grams per tonne silver over a core width of 22.9 metres (Assessment Report 28944). The IP anomaly associated with the Slide mineralization is open to the southeast into the Haha Creek valley with a 1.8 kilometre gap in geophysical coverage between the Slide and Boundary grids. This covered area has seen little previous work and could significantly expand the potential size of the Slide-boundary target.

While developing the Boundary (Tam) prospect (093N 093), UMEX (Union Miniere Explorations and Mining Corporation Limited) also carried out exploration programs in the Slide area documenting mineralization in outcrop in 1973. From 1973-75, UMEX conducted geological mapping, soil geochemical surveys, IP geophysical surveys and drilled three diamond-drill holes totalling 326.2 metres. The best results from this work was 0.43 per cent copper over 3 metres in hole T-17.

In 1990 and 1991, Major General Resources Ltd. and Varitech Resources Ltd. carried out programs of mapping, rock and soil sampling, IP and magnetic geophysical surveys over the Boundary, Midway and Slide showings but did not drill test any targets. A 10 metre random chip sample from the 1970s era Slide hand trench yielded 1.27 per cent copper from malachite stained, fine grained potassium altered gneissic monzonite or greenschist.

L.B. Warren staked claims over the Jan-Tam-Misty area several times since 1995; prospecting was intermittent to 2006 when Warren optioned the property to Teck Cominco Limited. In 2006, the work program included: 40.45 kilometres of line cutting, IP and magnetic geophysical surveys on the Misty (093N 001), Boundary (093N 093), and Slide grids, detailed mapping in the Misty, Boundary and Slide areas, property-wide geological mapping, an airborne radiometric and magnetic survey totalling 323 line kilometres and the drilling of 10 NQ diamond-drill holes totalling 3069.8 metres on the Misty and Slide targets.

Teck Cominco completed an extensive drilling program (about 5000 metres) concentrated on the Jan-Tam-Misty property in 2007. In 2008, the company completed about 1200 metres of drilling on its 2007 targets Boundary and Slide, and on one new target.

In 2012, Tajiri Resource Corp. conducted a helicopter supported property-wide reconnaissance geochemical investigation of their OGK property. A total of 68 rock, 112 stream sediment and 383 soil samples were collected and submitted for assay. A helicopter supported airborne geophysical survey consisting of magnetics, VLF/EM and radiometric surveys over four blocks totalling 505 line-kilometres was also completed. Samples from a 0.55-metre wide quartz vein, located near the western end of the saddle, assayed from 0.092 to 2.992 grams per tonne gold (Westphal, M. (2014-06-26): Technical Report on the OGK Property).

In 2019, the British Columbia Geological Survey conducted a regional bedrock mapping program in northern Hogem batholith and the surrounding areas. A sample was collected 800 metres northeast of the SLIDE occurrence, which yielded assay results of 7010 parts per million copper (Fieldwork 2019 pp. 25-47).
