The Peach 5 (or NK) copper showing is located 2 kilometres south of Peach Lake, approximately 20 kilometres northeast of Lac La Hache and is readily accessible from Highway 97 via a network of logging roads. Other names for the claims and showings have been the Ann, Peach and the Ophir. The Peach #5 showing is one of several copper showings on the current Ann 1 and 2 claims (see also 092P001, 002, 034, 035 and 153). All of these occurences are part of the Spout Lake copper-gold district, a group of porphyry and skarn deposits associated with Late Triassic to Early Jurassic alkaline intrusive rocks of the Spout Lake intrusive suite.

The Ann 1 and 2 claims are underlain by andesites, basalts, calcareous tuffs and argillites of the Late Triassic Nicola Group (Assessment Report 23976). Nicola Group rocks are intruded by the Upper Triassic to Early Jurassic Spout Lake Intrusive complex, an alkalic intrusive suite ranging in composition from pyroxenite through monzonite to syenite, and from batholithic size to small intrusive plugs, dykes and breccia bodies. Granodioritic rocks of the Triassic to Jurassic Takomkane Batholith intrude Nicola rocks east of the property. Outliers of alkaline plateau basalts of the Miocene to Pleistocene Chilcotin Group are present in the general area.

No good description of the Peach 5 deposit is available, however Assessment Report 3815, states that "chalcopyrite mainly occurs in veined syenodiorite (monzonite) at the contacts of monzonite porphyry. Also minor disseminated chalcopyrite occurs in monzonite and minor malachite" is present. K-feldspar and epidote are noted as alteration minerals. A drill hole intersected 89.3 metres of mineralisation grading 0.19 per cent copper and 0.23 grams per tonne gold (Property File, G.W.R. Resources Incorporated report, March 2001).

Interest in the Spout Lake area was triggered in 1966 when the Geological Survey of Canada released the results of a regional airborn magnetic survey which outlined an annular magnetic anomaly 10 kilometres in diameter in the Spout Lake area and which included the area underlying the Peach #1 prospect. Subsequently in 1966 and 1967, Coranex Limited abtained anomalous results in follow-up stream sediment geochemical surveys and soil geochemical surveys in the area south of Peach Lake. Programs of geological, soil geochemical, magnetometer, induced polarization and prospecting surveys were undertaken in 1967 in the area south of Peach Lake, leading to the discovery of the Peach 1 and several other occurences. Asarco Exploration Company of Canada Limited optioned the property in 1969. Amax Potash Limited optioned the property between 1971 and 1973 and completed programs of geological mapping, geophysics and percussion drilling. In 1983 and 1984, the Selco Division of BP Resources Canada Limited completed soil geochemical surveys on the Core group of claims which covered the property. G.W.R. Resources Incorporated acquired the property in 1988 and Asarco re-optioned the property and completed induced polarisation surveys and percussion drilling in 1991. In 1993, G.W.R. Resources formed a joint venture with Regional Resources and have since completed programs of induced polarization and diamond drilling. G.W.R. Resources has conducted additional diamond drill programs in 1999 and 2000.
