The Clapper 2 occurrence is located immediately east of the Coquihalla Highway and approximately 1.5 kilometres southeast of Helmer Lake.

The area is underlain by Upper Triassic Nicola Group andesitic rocks in fault contact with granodiorite of the Lower Jurassic Nicola Batholith. A coarse-grained diorite to quartz diorite is also evident and may represent a marginal phase of the batholith. The Nicola Group rocks consist of hornblende porphyritic andesite, andesite tuff and lapilli tuff, agglomerate, volcanic breccias, massive andesite and fine-grained diorite, which is apparently a subvolcanic equivalent of the andesite. Metamorphosed equivalents of the andesites are locally exposed and include greenstone, phyllite and quartz sericite schists. The latter two units appear to be related to localized shear zones. The andesitic volcanic rocks also contain local interbeds of limestone, siltstone and volcaniclastics.

Locally, a 5-centimetre wide zone in hematitic andesite is mineralized with pyrite, sphalerite, galena and malachite.

In 1988, a rock sample (239692) from this zone assayed 4.75 grams per tonne gold, 144.0 grams per tonne silver, 0.516 per cent zinc and greater than 1.00 per cent lead, whereas another sample (102853), taken approximately 900 metres west of the previous sample, yielded 0.63 gram per tonne gold (Assessment Report 18042).

In 2004, a rusty diorite boulder (float) sample (23888), located approximately 1.1 kilometres west-southwest of the occurrence, yielded 4.84 grams per tonne gold, 14.3 grams per tonne silver, 0.202 per cent copper and 0.126 per cent lead (Assessment Report 27476).

Work History

The area has been explored in conjunction with the nearby Clapper (MINFILE 092ISE135) and Clap (MINFILE 092ISE174) occurrences and a completed exploration history of the area can be found there.
