The Hop showing outcrops in the headwaters of the southern tributary of Blakeburn Creek, 2.1 kilometres east-southeast of the summit of Lodestone Mountain and 21.5 kilometres due west of Princeton.

The showing is hosted in syenite and syenogabbro of the Early Jurassic Tulameen Ultramafic Complex, near the eastern contact with metavolcanics of the Upper Triassic Nicola Group. These rocks exhibit extensive epidote alteration of feldspar and minor chloritization of hornblende.

Sporadic copper mineralization is exposed in outcrop over a length of 35 metres. The strongest mineralization occurs in the northern part of the showing, where a set of conjugate fractures, striking 128 and 210 degrees, cuts altered syenite. The fractures are filled with chalcopyrite and bornite, with or without quartz, over widths of up to 5 millimetres. Disseminated pyrite is scattered throughout the showing. A sample of a high-grade chalcopyrite stringer assayed 23.0 grams per tonne gold, 89.5 grams per tonne silver and 7.49 per cent copper, and a sample of intrusive with chalcopyrite and bornite assayed 1.3 grams per tonne gold, 30.5 grams per tonne silver and 4.00 per cent copper (Assessment Report 15106, page 7, samples 7303, 7307).

Minor copper mineralization also occurs in syenite, about 400 metres northeast of the main showing. A sample of epidote-altered syenite with malachite staining assayed 0.03 gram per tonne gold, 2.7 grams per tonne silver and 0.30 per cent copper (Assessment Report 15106, assay certificate, sample 7309).

Work History

The showing was explored by various operators between 1983 and 1988.

In 2018, GSP Resources Corp. completed a program of soil sampling and a 370 line-kilometre airborne geophysical survey on the area as the Olivine Mountain property. The following year, seven diamond drill holes, totalling 1200 metres, were completed on the Olivine Mountain property.
