The Eddy property is located on a ridge separating North Moyie and Ryder Creeks, approximately 28.0 kilometres south west of Cranbrook. A number of mineralized zones, covering roughly a 1 square kilometre area, have been explored on the property: Ryder Creek North, Ryder Creek South, Claim Creek, Claim Creek West and Gabbro. During 2009, Ruby Red Resources conducted a programme of prospecting and rock geochemistry on the property. A programme of soil geochemistry was continued the following year.

Regionally, the area is underlain by clastic sedimentary rocks of the mid-Proterozoic Purcell Supergroup, mainly the Middle and Upper Aldridge and the Creston Formations. The sediments have been intruded by gabbro/diorite sills and dikes (Moyie intrusions) that are interpreted to have come up into a wet sediment package. Later intrusive events are recorded by the emplacement of Cretaceous aged quartz monzonite and granodiorites of the Bayonne magmatic suite as well as a suite of carbonatite dikes and plugs. Structure in the area is reflected by the Moyie anticline, a broad, shallow north-plunging feature that is cross-cut by a number of northeast-trending fault systems with both normal and reverse movement, most importantly, from south to north, the Moyie Fault, the Cranbrook Fault, the St. Marys Fault, and the Kimberley Fault

Locally, there are a number of zones of silicification, albite, carbonate, pyrite, hematite, and chlorite related to north-northeast shearing, sympathetic to the Old Baldy Fault, as well as quartzite beds sandwiched between argillite. Also, disseminated sphalerite and tourmaline needles are noted in altered Middle Aldridge wackes.

The Claim Creek West zone is a broad zone of shearing within probable Upper Aldridge Formation argillite and narrow quartzite bands. Shearing and fracturing is trending roughly northeast and dipping moderately to steeply to the southeast. The overall width of the shear zone is greater than 325 metres. A zone of albitic, solidified, carbonate and chlorite altered quartzite breccias occurs within the shear and is exposed in a logging road over a distance of 55 metres. Base metals, including galena, sphalerite, and chalcopyrite are common in fractures within this zone and in the more albitic/siliceous matrix of the breccias. A sample, of the zone, returned 104.3 parts per billion gold, more than 100 parts per million silver, greater than 1.0 per cent lead, 242.5 parts per million molybdenum, and 545.3 parts per million bismuth (Assessment Report 31398).

The Claim Creek zone is an area of poorly exposed silica, albite, hematite and pyrite breccia. Samples taken from this area returned a maximum value of 1160 parts per billion gold (Assessment Report 31398).

The Gabbro zone consists of milky to crystalline quartz veins with minor chalcopyrite, malachite stain and pyrite in gabbro related to a Moyie sill. Gold values up to 138 parts per billion were encountered, with numerous other samples containing anomalous gold (Assessment Report 31398).

The Ryder Creek South zone is underlain by Middle Aldridge sediments and a Moyie sill in the southeast, the Old Baldy Fault juxtaposes Creston Formation with Middle Aldridge to the northwest. Locally, a zone of subcropping argiillically altered goethite, hematite and manganese stained rocks of altered Creston Formation occur over 60 metres. Quartz stringers with pyrite and goethite are common in the subcrop. During 2009, a 3.0 metre wide zone of silicified quartzite breccia with phyllite tops, goethite, open space quartz veins, manganese and carbonate was sampled, returning values up to 434.4 parts per billion gold (S JKR09-22; Assessment Report 31398).

The Ryder Creek North zone consists of silicified gold bearing Creston Formation sediments as described above. The Creston sediments in this area are dominantly quartzite with interbedded green argillite. This zone is in the hangingwall of the Old Baldy Fault. In the area, certain quartzite beds are brecciated and albite/chlorite altered, they contain quartz veins with feldspar and pyrite/goethite. Sampling of the area returned anomalous gold values up to 967.9 parts per billion (SJKR09-28). Immediately west of this area, the Creston Formation is in fault contact with a narrow section of Upper Aldridge argillite. The fault is marked by several more than 1 metre-wide bull quartz veins that are roughly parallel to the contact and bedding. An old pit on a quartz breccia was sampled and returned 449.8 parts per billion gold (SJKR09-37; Assessment Report 31398).
