Geology Comments

Mar 09, 2010 (D Guidon) - from Watts Griffis and McOuatt The central part of the Property is underlain by felsic and intermediate volcaniclastics of the Upper Tisdale assemblage (Figure 4). These rocks are interpreted to occur in the core of an east to east-southeast-trending, southeasterly plunging anticline – the Spectacle Lake anticline. The uppermost unit of the felsic volcanic sequence is a chert-pyritic tuffcarbonaceous sedimentary horizon. The Tisdale assemblage is conformably overlain by the Lower Blake River assemblage. This contact is located immediately south of the Upper Beaver mine shafts. The Victoria Creek Deformation Zone is in part spatially coincident with this contact between the older Tisdale and younger Lower Blake River assemblages. The majority of the north part of the Property is underlain by the Lower Blake assemblage. These rocks, (previously known as the Kinojevis) consist of an alternating sequence of strongly magnetic iron and magnesium-rich tholeiitic basalts. The southern part of the Property is underlain by Timiskaming volcanics, volcaniclastics and sediments, however, the age of these sediments is currently being debated. This sequence is in fault contact with Tisdale assemblage rocks. Syenite complexes of Timaskaming age intrude both the Tisdale, Blake River and Timiskaming assemblages. Various intrusive phases are present. The two main syenite phases are a dark grey mafic syenite and a red-brown to dark grey feldspar phyric syenite with an aphanitic matrix. Feldspar porphyry phases are also present. A prominent plug of syenite and mafic syenite, 600 m in diameter, occurs 250 m north of the #3 Shaft. A feldspar porphyry intrusion lies adjacent to its margin. Matachewan diabase dykes cut all other rock units. The north-trending Misema Fault follows the Misema River. A diabase dyke, 30 to 40 m thick follows this structure. The mafic volcanics east, west and north of the syenite plug strike east-west and dip 70-80º to the north. Three sets of faults have been mapped as follows: • northwest-trending and steeply dipping northeast, • northeast-trending and steeply dipping northwest, and • east-west striking faults, dipping steeply north through the syenite plug and mafic volcanics.

Lithology

Mineralization

Mineralization Comments

Mar 09, 2010 (D Guidon) - from Watts Griffis and McOuatt The Upper Beaver deposit is an Archean gold lode deposit where mineralized zones are structurally controlled and consist of brittle to ductile discontinuous, anatomising structures. Such deposit types are common along the CLLDZ in the Kirkland Lake area where precious metal production has exceeded 40 million ounces. Details for these deposits are, however, highly variable. Common features include regional and local structural control and spatial and temporal relationship with felsic to alkalic intrusives. Not-typical for the Kirkland Lake camp is the copper-gold association at Upper Beaver with the widespread and pervasive development of magnetite-feldspar-actinolite-epidote and carbonate-sericite. These features are more consistent with some deposits in the Timmins camp along the Destor-Porcupine Fault Zone. Kontact, Dube and Benham have suggested that the Upper Beaver deposits are consistent with an alkali porphyry copper-gold model. Mineralization at Upper Beaver, as described by Queenston (Kontack, Dube and Benham, unpublished): • occurs both in flat and steeply dipping zones; • is of replacement-type with rare vein-type mineralization; • is associated with minor to pervasive alteration which includes feldspathic, epidote, carbonate, sericite, silica and magnetite with trace hematite; and • has an element association of Cu, Au, or Au-Cu with associated molybdenum. Queenston classifies the mineralization as three main groups of zones (from south to north): • South Contact Zones; • Beaver North Zones; and • North Basalt Zones. The vein systems are complex. Sufficient data is often not available to define a true width. As a rule of thumb, the more steeply dipping zones in the Beaver North and North Basalt Zones are estimated to have a true width factor of 70 to 77% of the core length interval, while the more flatly dipping South Contact mineralization ranges from 90 to 100% of the original intersection. The composite cross section from the previous NI 43-101 report illustrates schematically the South Contact and Beaver North zones, their orientations / structures and host rocks that contain the mineralization.

Alteration Comments

Mar 09, 2010 (D Guidon) - - Continuation of mineralization Mineralization also is zoned both with depth and laterally towards the central parts of individual zones. Early 1920s-1935 historic production came from gold quartz veins with low copper ratios, however, historic 1965-1972 production was from gold-bearing quartzchalcopyrite-magnetite veins with high copper ratios. The central portions of the Porphyry Zones are chalcopyrite-magnetite rich. Laterally towards the east and west margins of the zones, pyrite becomes the dominant sulphide while chalcopyrite and magnetite decrease. Near the margins, the zone width is less than 1 m quartz-calcite veins, usually with visible gold. Outside the margins of the mineralized zones there is a chlorite-epidote-carbonate altered fractured to brecciated zones. Vertically, the width of zones typically increase from an average of less than 1.5 m in the volcanics, to greater than 5 m in the syenite and mafic syenite porphyry rocks most, likely due to the more brittle nature of the intrusive rocks. There is an apparent increase in gold grades with depth from 3 g Au/t at the -400 m level to +10 g Au/t below the -500 m level. The Porphyry Zone are still open at depth, so it is not known if there is a similar quartz-sulphidemagnetite zoning towards the bottom of the zones, as is the case laterally. High gold ratios are not directly related to the chalcopyrite and magnetite content of the mineralized zones.
