Point Location Description: headframe
Location Method: Field Visit with GPS
Access Description: The deposit is located about 20 km west of Timmins along Highway 101. Access is very easy as the main showing is less than a kilometre from Highway 101 along an old logging road. The turn off is on the south side of the highway just east of the main intersection with Highway 144. Cross an old bridge over Thunder Creek and turn left at the intersection. This road has now been washed out by run off just short of a large stripped area exposing the showing.

Province: Superior
Subprovince: Abitibi
Terrane: Wawa-Abitibi
Belt: Abitibi
Geological Age: Neoarchean
Metamorphism Type: Regional
Metamorphism Grade: Greenschist
Dec 07, 2005 (S Fumerton) - Mineralization is strongly controlled by the older structural features. The sheared basalts and arenites form the preferred host to the mineralization and the mineralized chutes are orientated parallel to the dominant early fold axis. The older shear zone is not easy to discern and in the past has been mistaken for metasediments. This shear strikes east - west and dips steeply to the north. The dominant fold axis is typically the only discernible fold to be seen in most outcrops and in this area, this axis plunges steeply to the west in the plane of the older shear zone. The late fault which has been called the Bristol fault, consists of an unconsolidated breccia zone with a narrow fault plane filled with unconsolidated gouge. The character of this fault is dissimilar to the Destor - Porcupine Fault.
Dec 07, 2005 (A Wilson) - Two significant structures occur in the area. The first is the Bristol Fault that strikes to the east, and in the area of the deposit, dips to the north. In the deposit area, the Bristol Fault is a 1-2 m wide fault gouge that cuts across the volcanic-sedimentary contact. The second feature is a strong deformation zone that cuts through the deposit. These features are believed to be part of the continuation of the Porcupine-Destor Fault.

Dec 07, 2005 (S Fumerton) - The Holmer deposit is located some 10km west of the southern group of gold mines in the Porcupine camp with which it has a number of similarities. The prospect is located on a small fold in the sediment/volcanic contact where it is cut by an older shear zone and a younger fault. The meta volcanics in the immediate area are divided into an Fe tholeiitic and Mg tholeiitic suite, and appear to have an unconformable contact with the adjacent arenites which form a turbidite sequence. Closely associated with the prospect is a small gabbroic and ultramafic intrusion with which in turn a number of diverse though small felsic and carbonatitic intrusions are associated with. All these intrusions are thought to post date mineralization.
Dec 07, 2005 (A Wilson) - From north to south In the deposit area, the lithologies consist of extrusive and intrusive ultramafics, mafic volcanic flows, sediments, mafic volcanic flows, sediments, Bristol Fault and Porcupine sediments.

Dec 07, 2005 (S Fumerton) - Within the metavolcanics a clear progressive alteration sequence is apparent yet within the metasediments only the ultimate alteration phases are discernible. The alteration in the volcanics consists of:- 1) widespread calcite alteration, 2) a narrow subtle graphitic front, 3) appearance of sericite in increasing amounts, 4) replacement of calcite by dolomite, 5) tourmalinization, 6) albitization, and finally silicification. Gold mineralization is associated with the tourmalinization and is apparently downgraded by the albitization and silicification. Secondary remobilisation resulted in the formation of numerous quartz veins small and large in many orientations. There are also a number of tourmaline veins. Gold mineralization is enriched in both these veins and these veins contain all the known visible gold occurrences. Pyrite is the most common sulphide occurring in various forms but is typically disseminated in low concentrations throughout the alteration zones. Arsenopyrite is restricted to the tourmalinized zones and occurs in fine or course disseminated grains. Larger euhedral grains of these sulphides together with traces of chalcopyrite, galena, and sphalerite occur in the remobilised veins.

Date: May 28, 1992
Geologist: S Fumerton
Notes: Brief visit to check position with GPS unit. Since the area was stripped in 1988 the water level in the pit has risen a little and the growth of moss on parts of the outcrop has started to obscure some of the subtle geological features.
Date: Aug 03, 2004
Geologist: A Wilson
Notes: Six zones of mineralization occure on the property. All zones are localized within a 150-200 m wide zone of alteration and deformation. The style of mineralization consists of high-grade mineralized quartz veins in steeply dipping ore shoots. The veins are ususally associated with the sediment-volcanic contact. The Main Zone is a pipe-shaped body of quartz-tourmaline veins and lenses in the nose of a fold at the contact between sediments and volcanics. Gold values correlate with associated pyrite and arsenopyrite. Mineralization in the Hanging Wall Zone is similar to the Main Zone. Quartz-tourmaline veins occur along the volcanic-sediment contact. Visible gold is common within the vien system. Mineralization in the Footwall Zone occurs within a unit of mafic tholeiitic volcanic rocks near or at the contact of the ultramafic complex. Gold is concentated in highly sheared and mylonitized rocks associated with silica, albite and pyrite alteration. Gold values appear to increase with depth in this zone. The Ultramafic Zone appears to be associated with a fine-grained carbonatite, and coarse-grained ultramafic intrusives/flows. Gold mineralization is associated with pyrite and chalcopyrite in altered zones.
