The Man copper prospect is located approximately 1200 metres east of Summers Creek, 2.3 kilometres southeast of the south end of Missezula Lake and 32.5 kilometres north of Princeton.

This region along Summers Creek is underlain by the Eastern volcanic facies of the Upper Triassic Nicola Group, comprising mafic to intermediate, augite and hornblende porphyritic pyroclastics and flows, and associated alkaline intrusions. The intrusions vary in composition from diorite to monzonite and are thought to be comagmatic with the Nicola Group, ranging in age from Upper Triassic to Lower Jurassic. Much of the copper mineralization and associated alteration frequenting this portion of the Nicola Belt can be attributed to the emplacement of such intrusions.

Locally, the area is underlain by Nicola Group plagioclase hornblende porphyritic andesite flows and massive to crudely bedded lahar deposits containing pink syenitic clasts (Eastern Belt, Bulletin 69). This sequence is intruded by a complexly faulted assemblage of hornblende porphyritic syenite, locally grading to monzonite or syenodiorite, and hornblende porphyritic diorite. Various fault blocks of barren, unaltered syenite occur north of similarly faulted, altered and mineralized syenite. The hornblende diorite flanks the syenite to the southwest.

The mineralized syenite exhibits strong argillic and sericitic alteration and weak to moderate chlorite and albite alteration. The surrounding mineralized andesites contain weak to moderate, patchy orthoclase; lesser chlorite, silica, sericite and clay; and traces of secondary biotite. The intrusive and volcanics are commonly veined with gypsum and calcite, lesser quartz and minor zeolite. Some orthoclase flooding is developed along the quartz and gypsum veins.

The intrusion contains up to 3 per cent pyrite and up to 2 per cent chalcopyrite as disseminations, blebs and fracture fillings. Traces of bornite and chalcocite are also evident. Surface exposures contain abundant malachite along fractures in the syenite, and some azurite confined to narrow fault-bounded zones 1 to 3 metres wide. Neotocite occurs as small black masses through the altered syenite. Chalcopyrite is occasionally found in siliceous zones and quartz veins in the andesite, and along gypsum veins and chloritic fractures.

In 1979, sampling of trenches yielded up to 0.583 per cent copper, 4.1 grams per tonne silver and 1.4 grams per tonne gold (Sample 6798; Assessment Report 7584).

By 1981, diamond drilling and trenching had intersected significant copper and gold mineralization over an area of 260 by 300 metres. The bulk of the copper mineralization occurs in one prominent north-trending zone, 200 to 225 metres long and 10 to 30 metres wide, averaging 0.3 to 0.4 per cent copper and 0.31 gram per tonne gold with up to 6.8 grams per tonne gold over 3 metres in hole 80-1 (Assessment Report 13231 and 16985; Property File - D.C. Miller, 1988, page 6). The zone dips 75 degrees to near vertically east and has been tested to a depth of 230 metres. Drilling suggests that gold mineralization occurs in fault zones separating mineralized rock from fresh unaltered rock, and in narrow steeply dipping zones paralleling the main zone of copper mineralization.

Other specific drilling intercepts included 0.31 per cent copper and 0.4 gram per tonne gold over 6 metres (197.0 to 203.0 metres down hole) and 0.23 per cent copper with 1.4 grams per tonne gold over the final 3 metres (230.4 to 233.4 metres down hole) of hole 81-1, and 0.16 per cent copper over the final 9 metres (230.0 to 239.0 metres down hole) of hole 81-2 (Assessment Report 9367). These holes were located approximately 120 metres south of the previously trenched zone. Also at this time, sampling of trenches yielded significant gold values, including 8.6 grams per tonne over 5 metres and 3.57 grams per tonne over 14 metres (Assessment Report 16985 and 17077).

Additional drilling in 1988 and 1989 intersected mineralization over a 200- by 200-metre area to depths of up to 158 metres. An angled drillhole (321-1) yielded 0.29 per cent copper and 0.27 gram per tonne gold over 193.85 metres (15.54 to 209.39 metres down hole), including 1.52 per cent copper and 10.1 grams per tonne gold over 1 metre, whereas two vertical holes (321-8 and 321-7), collared approximately 140 metres southwest and 100 metres northeast of hole 321-8, graded 0.18 and 0.43 per cent copper with 0.10 and 0.21 gram per tonne gold over 68.58 and 11.72 metres (89.00 to 157.58 and 11.28 to 23.00 metres down hole), respectively (Assessment Report 18776).

In 2007, drillholes 694-007, -008, -012 and -013 extended the mineralized zone 150 metres to the southwest and to a depth of approximately 200 metres. Drilling intercepts included 0.35 per cent copper and 1.41 grams per tonne gold over 22.0 metres in hole 694-008, 0.21 per cent copper and 0.39 gram per tonne gold over 92.0 metres in hole 694-012 and 0.26 per cent copper and 0.46 gram per tonne gold over 56.0 metres in hole 694-013 (Assessment Report 31709).

In 2008, two diamond drillholes (858-021 and -022) on the northeastern portion of the mineralized zone yielded intercepts including 0.22 and 0.22 per cent copper with 0.61 and nil gram per tonne gold over 14.0 and 24.0 metres, respectively, whereas another hole (858-025), located near the centre of the mineralized zone, yielded 0.13 per cent copper over 44.0 metres (Assessment Report 31709).

In 2007 or 2008, sampling of a roadcut exposing copper mineralization yielded 0.109 per cent copper and 0.21 gram per tonne gold over 6.0 metres (Assessment Report 31709).

In 2018, a sample (D3) from a historical trench yielded 0.815 per cent copper and 0.142 gram per tonne gold (Assessment Report 37988).

Another area of chalcocite and malachite mineralization is reported approximately 400 metres southwest of the main mineralized zone, whereas two other outcrops, located approximately 800 and 1000 metres south-southwest of the main zone, host chalcopyrite mineralization.
