The Sadim gold prospect is 2.3 kilometres west of Summers Creek and 28.5 kilometres north of Princeton.

The 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 a sequence of intermediate to mafic flows, breccias and tuff, and lesser argillite and limestone of the Nicola Group (Central Belt, Bulletin 69). These beds strike slightly west of north and dip moderately to steeply east. The volcanics and sediments are propylitized with abundant epidote-pyrite-chlorite-carbonate and host erratic copper-pyrite zones.

The volcanic rocks are cut by a major east-dipping shear zone, possibly a thrust fault, which trends north and ranges up to 15 metres in width. The zone occurs along a dark-grey carbonaceous limestone and separates andesitic flows and tuffs to the west from mixed tuffs to the east. The shear has caused intense fracturing and alteration in the adjacent tuffs, especially in the hangingwall. The tuffs are moderately to strongly carbonatized and variably silicified. A sample of an andesitic tuff contained plagioclase crystals and minor quartz in a fine-grained carbonate matrix.

A quartz vein stockwork is developed in the hangingwall tuffs. The stockwork is comprised of quartz veins ranging from less than a millimetre to greater than 1 metre in width. Two prominent sets of veins comprise this stockwork. One set strikes 060 degrees and a second set strikes 120 degrees. All veins dip 50 to 70 degrees south. The quartz veins are erratically mineralized with disseminated sulphides, consisting mostly of pyrite and chalcopyrite, and lesser galena. Petrographic studies also indicate traces of sphalerite and lead and silver tellurides (altaite and hessite). The sulphides commonly occur along vuggy vein margins or in the centre of the veins. The precious metals content of the stockwork is directly related to the intensity of quartz veining, fracturing and sulphide content. Galena is strongly associated with higher gold and silver values. Gold to silver ratios are remarkably constant at approximately 1 to 8 (Assessment Report 16889). The nature of this mineralization and alteration suggests the deposit is of mesothermal origin (Assessment Report 16889).

Diamond drilling and trenching have intersected two zones containing significant gold. The Main zone contains the bulk of the gold-bearing stockwork mineralization. The stockwork and associated alteration are best developed over a north-south distance of approximately 100 metres. To the north, the zone grades into unaltered, barren tuff, whereas to the south, the zone is interpreted to be truncated at surface by a northeast-striking fault. The zone appears to be open downdip to the east. Drilling indicates precious metal content increases from south to north.

A similar zone of shear-controlled alteration (East zone), trends north, parallel to and within 100 metres northeast of the Main zone. The zone contains several large quartz veins approximately 1 metre wide. Another zone of mineralization (North zone) is exposed by trenches approximately 650 metres northwest of the Main zone and comprises a narrow zone of altered tuff containing quartz veins with gold values associated with an irregular northwest-trending shear/alteration zone up to 6 metres wide.

Later work (circa 1994) identified east-west-trending quartz veins several hundred metres north of the original (Main zone) veins and trenches. The veins have been exposed by trenching over a distance of approximately 66 metres.

In 1985, a select sample (2247) of quartz vein material from a trench on the Main zone yielded 6.31 grams per tonne gold and 62.0 grams per tonne silver, whereas chip samples of pyritized wallrock yielded from 0.225 to 0.560 gram per tonne gold (Assessment Report 14044).

In 1987, chip sampling of trenches yielded gold values of 0.050 to 4.35 grams per tonne over 1 metre (Assessment Report 15969, page 9). Later that year, drilling intersected gold mineralization in vein-clusters and stockworks 2 to 24 metres thick. Drillhole 87-6 yielded 3.57 grams per tonne gold and 25.4 grams per tonne silver over 9.3 metres (21.5 to 30.8 metres down hole; Assessment Report 16889, Figure 11a). Also at this time, an east-striking, steeply south-dipping quartz vein from the East zone assayed 151.1 grams per tonne gold and 410.9 grams per tonne silver over 1.0 metre (Assessment Report 16889, page 10).

In 1994, chip sampling of the main mineralized vein exposed in trench 94-2 yielded an average of 37.3 grams per tonne gold over a width of 0.78 metres and a length of 19 metres, including 379 grams per tonne gold and 2900 grams per tonne silver across 0.2 metre, whereas a grab sample of quartz and gouge from trench 94-3, located on the North zone, yielded 16.1 grams per tonne gold and 114 grams per tonne silver (Assessment Report 23775).

In 1995, diamond drilling is reported to have yielded intercepts including 103.96 grams per tonne gold and 200.7 grams per tonne silver over 0.3 metre (19.5 to 19.8 metres down hole) in hole 95-8 and 15.50 grams per tonne gold with 134.9 grams per tonne silver over 1.1 metres (142.0 to 143.1 metres down hole) in hole 95-11 (Assessment Report 26944).

In 2000, a grab sample (KHS1001) from trench 20-1, located 32 metres south of the previous 1994 trench 94-2, yielded 23.99 grams per tonne gold and 196.0 grams per tonne silver, whereas a nearby chip sample (KHS1000) yielded 7.73 grams per tonne gold and 54.6 grams per tonne silver over 0.4 metre (Assessment Report 26421).

In 2002, diamond drilling yielded intercepts of up to 48.06 grams per tonne gold and greater than 99.99 grams per tonne silver over 0.15 metre (80.90 to 81.05 metres down hole) in hole 02-9 (Assessment Report 26944).

In 2009, two chip samples (S-05 and S-06) of quartz vein float and subcrop yielded 48.615 and 5.286 grams per tonne gold, greater than 100 grams per tonne silver and 55.2 grams per tonne silver with 0.300 and 0.012 per cent copper, respectively (Assessment Report 31138). The following year, a grab sample (55143) of quartz vein rubble with traces of pyrite and galena assayed 2.364 grams per tonne gold (Assessment Report 31916).
