Capsule Geology

The Golden Arrow area is underlain by a sequence of folded and faulted upper Triassic andesitic volcanic and clastic sedimentary rock units of the Stuhini Group. The sequences of clastic layered rocks consist of volcanic wackes, andesitic flows, and argillite interbeds.

Intrusive bodies include an orthoclase porphyry plug at the junction of Bronson Creek and the Iskut River and a large quartz monzonite to granodiorite intrusion along the east margin of the property.

The volcaniclastic is described as andesitic agglomerate, comprised of unreworked volcanic fragments up to 2 centimetres in length and subrounded to subangular feldspar porphyry clasts. The matrix of this porphyry consists of an aphanitic mass of andesitic to basaltic composition which exhibits pervasive chlorite alteration. The agglomerate has undergone weak regional greenschist facies and is altered by pervasive carbonate, chlorite and to a lesser extent, epidote. The agglomerate also hosts 1 to 3 per cent disseminated magnetite.

Mineralization on the Waratah property may be classified into three catagories: copper-gold veins (refer to Waratah 6, 104B 204) and copper-lead-zinc-silver-gold veins (refer to Gold Bug, 104B 295) both within andesitic agglomerate and native gold-pyrite veins associated with a monzonite intrusion.

The Golden Arrow showing and a second vein to the west, are located in the eastern part of the property. The Golden Arrow showing consists of a relatively unaltered monzonite intrusive body hosting a 10 to 30 centimetre wide quartz-chlorite vein mineralized with pyrite, native gold and an unidentified steely-blue mineral that is associated with the gold deposition. The pyrite exhibits a number of textural styles including fine disseminations, coarse crystalline grains and banding which may indicate more than a single phase of deposition.

Wallrock alteration consists mainly of chlorite and pyrite which is restricted to only a few centimetres on either side of the vein structure. Minor carbonate is associated with the quartz veining.

The Golden Arrow vein is controlled by about a 70 degree trending fracture with a moderate dip to the south and is offset by several northwest trending faults with minor right lateral movements.

A 0.33 metre wide chip sample of quartz-chlorite veining, taken across the Golden Arrow vein assayed 53.28 grams per tonne gold and 22.67 grams per tonne silver. Another 0.23 metre wide chip sample assayed 151.9 grams per tonne gold and 2.0 grams per tonne silver (Assessment Report 16904).

No follow up work was done on the Golden Arrow showing after the 3 trenches were excavated in 1987 by Tungco Resources and none was recommended due to the limited nature of the showing.

Refer to Gold Bug (04B 295) for details of a common work history.
