The 900 zone is located west of Mineral Creek, approximately 800 metres north of China Creek.

The area is underlain by andesitic to basaltic flows, pillowed basalts, tuff, agglomerates, cherty tuffs and chert of the Devonian Duck Lake and Nitinat formations of the Paleozoic Sicker Group. The north-northeast striking Mineral Creek fault cuts the volcanic sequence, which trends 140 degrees (subparallel to the fault) and dips 20 to 40 degrees east. A volcaniclastic interval overlies and is in sharp contact with mainly aphyric and amygdaloidal basalt units. The volcanic rocks are intruded by an andesitic porphyry body.

The 900 zone is located 1300 metres southwest of the Mineral Creek zone (092F 079 - Debbie) and 200 metres west of the Mineral Creek fault. A lean iron formation with a magnetite-rich base is locally isoclinally folded. Beneath and crosscutting the chert horizon is a quartz vein stockwork which may be younger (Tertiary?) in age. Native gold, pyrite, magnetite and arsenopyrite occur in quartz veinlets in the chert and jasper and also in narrow carbonate veinlets. The 900 zone contains gold in magnetite-jasper-sulphide- bearing bedded chert, in quartz veins and in stockworks cutting ankeritic aphyric pillow basalt. The mineralized area strikes north for 180 metres, is 150 metres wide and over 120 metres deep. The 900 zone is a pipe-like body which occurs in a flexure resulting from the offset of the north-northeast 900 fault by a west-northwest fault.

Three different geological environments host gold 1) the cherty iron formation which is generally flat and folded 2) a north trending, steeply west dipping fault which contains a quartz stockwork and 3) the intersections of a series of moderately altered east trending faults with the north trending faulted quartz stockwork underlying the cherty iron formation.

Drilling on the 900 zone in 1988 intersected quartz stockworks with visible gold, and a series of northerly trending narrow quartz veins south of the stockwork which contained native gold. Trenching to expose high grade gold veins and diamond drilling to test the strike projection was proposed for 1989.

Inferred reserves (geological mineral inventory or volume of mineralized rock) for the 900 zone are estimated at 28,285 tonnes grading 11.65 grams per tonne gold (Northern Miner - December 18, 1989).

Several old trenches and an old shaft explore the mineralized zone.

White Hawk Ventures Inc. has shipped 894 tonnes of ore from the 900 zone to Bow Mine's mill at Greenwood. From there, 7478 kilograms of concentrate has been shipped to Cominco for refining (GCNL #219 (Nov.14), 1997).

From 2006 through 2008, Bitterroot Resources Ltd. drilled 60 holes in the Linda area, most targeted to test the Linda Zone (Ember and HW veins, MINFILE 092F 079), to the north.
