Mar 15, 2016 (R Pressacco) - All of the stratigraphic units at the Hoyle Pond Mine and the 1060 Zone (with the exception of the younger diabase dikes) have been affected by deformation events which are manifested as strong cleavage fabrics, lineations, and folds. Rhys recognized two main stages of deformation, with 2 weak, overprinting crenulation cleavages. Very little physical evidence is present to document the first deformational event (D1), aside from the observation that the symmetric distribution of the Mg-tholeiitic volcanic rocks and clastic sediments about a core of ultramafic volcanic rocks suggests the presence of an anticlinal fold with a closure in the 1060 Zone area. Evidence for the second phase of deformation (D2) includes a steeply north dipping, northeasterly trending slaty cleavage that forms the main cleavage which is visible in the mine. It is developed throughout the Hoyle Pond Mine with variable intensity and has consistent strikes in the 240-255 deg. range. In the 1060 Zone area, the S2 cleavage cuts across the ultramafic/mafic contacts in the core of the Hoyle Anticline. The S2 cleavage is defined by a strong preferred orientation of platy minerals (chlorite and sericite), and flattening of pillows and other marker features. An elongation lineation (L2) that plunges steeply to the north-northeast on foliation surfaces is observed in various lithologies in the mine. Younger structural features present in the mine area include a crenulation cleavage (S3), kink banding (S4), minor brittle faults, and calcite-filled joints. The S3 crenulation cleavage is only locally developed, dips shallowly to the west and southwest, and is axial planar to rare, open minor folds of S2 foliation which have amplitudes of less than 0.5 metres.

Mar 15, 2016 (A Wilson) - The Hoyle Pond Mine occurs within the Tisdale Assemblage, 4.5 m north of the Destor-Porcupine Fault. The mine occurs in a sequence of south-facing 065º striking, steeply north-dipping, magnesium-rich tholeiitic basealts.
Dec 07, 2005 (R Pressacco) - The property scale geology of the Hoyle Pond Mine and 1060 Zone area is relatively straightforward. An easterly trending, steeply north dipping band of Mg- and Fe-tholeiitic mafic volcanic rocks and ultramafic volcanic rocks is flanked both north and south by clastic metasedimentary rocks containing minor amounts of intercalated graphic argillite. The ultramafic volcanic rocks are situated in the central portions on this band, mostly to the west of section 101750E on the mine grid, such that a thin interval of Mg-tholeiite mafic volcanic rocks is present between them and the flaking sedimentary rocks. Some Fe-tholeiites have been documented along the southern sedimentary contact by Downes et. al. (1984). The overall easterly trend is maintained throughout the property except in the immediate vicinity of the Hoyle Pond shaft where the Mg-tholeiites are observed to take on an overall Z-shape as a result of either tight folding or a system of northeasterly trending faults / shears. The sediments are composed of a mixture of carbonaceous argillites and greywackes which become increasingly more argillaceous near the mafic contacts. The argillites exhibit a compositional banding defined by alternating 1 - 2 mm thick dark and light coloured argillaceous layers. Karelse (1985) determined that these sediments were fine grained turbidites on the basis of preserved Bouma cycles. The sediments contain trace amounts of porphyroblastic and nodular pyrite, and have a pronounced fabric defined by closely spaced fracture cleavage and flattening of the pyrite nodules. In the northern sediments, the intensity of the fabric increases southwards towards the volcanic contact. Rapid changes in facing directions are observed along the strike length of both the northern and southern sediments, suggesting tight folding.

Apr 19, 2016 (A Wilson) - Most of the gold is structurally controlled and occurs in three predominant forms. Most of the gold at Hoyle Pond is hosted along the selvages of quartz veins and wall rocks or in stylolitic fracturs within quartz veins and is commonly accompanied by hydromuscovite. Gold associated with amorphous carbon occurs as refractory ore. Chlorite, sericite-carbonate alteration and silicification in the form of quartz veins and stringers accompany the gold mineralization. Sulphide mineralization is generally less than 5%. A distinctive type of alteration referred to as grey zones by the mine geologists is diagnostic of gold mineralization at the Owl Creek, Hoyle Pond and to a lesser extent at the Bell Creek mines. Amorphous carbon accompanied by enrichments in silica, calcium, potassium, iron, arsenic and gold form sharply bounded to diffuse alteration zones which are the primary exploration targets in the southern part of the township. The discovery hole at the Hoyle Pond Mine was drilled by Texas Gulf Sulphur Company Inc. in 1969 with hole DDH 69-17 intersecting 6.5 g / t Au / 3.0m (0.18 oz / ton / 9.8ft). Subsequent drill programs in 1980 and 1982 outlined a deposit containing 199 600 tonnes grading 15.1 g / t Au (97 670 oz Au).
Mar 15, 2016 (R Pressacco) - At least two, and possibly three generations of auriferous quartz veins are observed in the Main Zone and 1060 Zone area (Rhys 1996). While all of the rock types in the mine form hosts to the aurferous veins except the diabase dikes, the veins are most abundant, thickest, and most continuous within the basaltic units. The three vein types are: Grey Quartz Veins: These early grey quartz>albite +/- tourmaline + carbonate + hydromica (hydromuscovite) + carbon veins are commonly surrounded by 'grey zone' alteration halos (Rye 1987). These veins are commonly ribboned with dark grey bands of tourmaline, carbon and carbonate that are either discrete aggregates of these minerals, or are pervasively disseminated throughout the quartz. The bands commonly contain, or are spatially associated with, coarse native gold. The banding may represent cyclic opening of the veins in a crack-seal fashion. The veins vary from <0.1m to 3 metres in thickness, but are thicker where later generations of quartz have further dilated the vein. Grey quartz veins are commonly folded and boudinaged by the S2 cleavage. White Quartz Veins: These veins are of intermediate age, and consist of white, milky quartz that contains <1 to 3% ribbons and bands of chlorite, muscovite, carbonate and pyrite that are commonly ribboned in texture. This type of quartz further dilates the older grey quartz veins, often brecciating them. The result is composite veins that contain brecciated fragments of grey quartz, or locally banded areas of grey quartz that are separated by the younger white quartz. In the 1060 Zone area, 0.5-3% disseminated pyrite occurs in the wall rocks to this type of vein. Gold is typically finer grained than in the grey quartz, and is often associated with the pyrite.
Mar 15, 2016 (R Pressacco) - In brief, the 'grey zone' style of alteration is closely associated with many of the gold-bearing quartz veins at Hoyle Pond and typically occurs as asymmetrical alteration selvages around a central quartz vein. In places 'grey zone' alteration does exist without the presence of a quartz vein, and while elevated gold values may be present in the altered zones, the alteration zones alone do not usually constitute ore. The grey alteration zones are recognized chiefly through a variation in the colour of the host rocks from a light green - grey in unaltered host rocks, through a light grey colour on the outer margins of the zones, to a dark grey to black colour as the central portions of the zones are approached. For the most part the alteration zones occur as bands, isolated pods, and at times as anastomosing three dimensional networks which surround lenses of less altered Mg-tholeiites. They trend generally towards an azimuth of 0608 and dip vertically. The zones can reach strike lengths on the order of 500m, and vary rapidly in width from 0.5m to 20m or more along strike or down dip. For the most part however, the intensity of alteration increases inwards toward a central core. The margin of an alteration zone is marked first by a subtle colour change from a buff green colour to a grey-green basalt and a noticeable increase in foliation intensity occurring over approximately a 1m interval. These marginal areas lack significant pyrite mineralization or brecciation. Toward the center of the alteration zone, the rock becomes perceptibly darker in colour and becomes enriched in 1 - 5 mm sized grains of recrystallized pyrite in roughly 2 - 5% overall abundance. A fine network of 1 - 2 mm wide carbonaceous fractures and randomly oriented carbonate stringers also become increasingly common, causing a fine brecciation of the host volcanic rocks.

Geologist: R Pressacco
Notes: Gold mineralization on the Kinross land holdings in Hoyle-Whitney-Matheson Twps area occurs in close association to quartz veins with associated wall rock alteration halos. To date, the known mineralization occurs as a number of vein swarms located in several areas such as: the Bell Creek Deposit (past producer), the Blackhawk (Vogel) Zone, the Owl Creek Deposit (past producer), the Owl Creek East Zones (350 Zone and 950 Zone), the Hoyle Pond Deposit (in production), the 1060 Zone (in production), and the Sediment Zone. At the Hoyle Pond Mine, the Main Zone includes a series of veins that strike in a general east to northeast direction. At least 7 of these veins have been of economic significance (7, 10, 12, 13, 14, 16, and 17 veins). The 1060 Zone at Hoyle Pond consists of at least 5 main vein structures (1060, B1, B2, B3, A, and Porphyry Veins).
