Jul 28, 2016 (R Degagne) - The Mattawasaga deposit is immediately north of a regional scale east northeast striking magnetic high (OGS 1984). Because the deposit is nowhere exposed on surface, and information concerning it is derived exclusively from diamond drilling completed by Amax Minerals Exploration, Canamax Resources, and American Barrick Resources Corp. from the Holt- McDermott Mine area, located a few kilometres along strike to the west. It is noteworthy that the interpretation of regional scale aeromagnetic data for the area suggests that the feature which Satterly originally interpreted to be the Ghostmount Fault would more recently have been interpreted to be instead a lithologic contact zone, as is done routinely farther south within the Kinojevis Group. Satterly cited as evidence for the existence of the Ghostmount Fault: a) the presence of a magnetic anomaly; b) the intersection of a fault by a single diamond drill hole located precisely where the Ghostmount Fault was interpreted to join the PDFZ; and c) possible dextral offset across the proposed fault zone in Harker Township of a north striking diabase dike. A 'bedding fault' identical in megascopic appearance to the McKenna Fault of the Holt-McDermott Mine area is reported (assessment files) to be closely associated with the Mattawasaga deposit Footwall zone. At the Holt-McDermott Mine, the McKenna Fault is a narrow, laterally continuous, steeply south dipping zone of gouge which near surface defines a hanging wall horizon north of which the ore zones occur. In the Mattawasaga deposit all known significant gold mineralization is south of this bedding fault and north of the Ghostmount Fault of Satterly.

Dec 07, 2005 (R Degagne) - The area may be conveniently divided into 3 domains: that area north of the Porcupine-Destor Fault Zone (PDFZ), that area south of the PDFZ, and the PDFZ itself. North of the PDFZ, in southern Lamplugh and Frecheville Townships and in the northern parts of Harker and Holloway Townships, bedrock consists mainly of weakly metamorphosed (greenschist or lower metamorphic facies) folded calc-alkalic volcanic and pyroclastic rocks of the (Archean) Hunter Mine Group, the oldest rocks in the area. In the Ghost Range area, exposed in an erosional outlier, younger shallowly northeast dipping (weakly metamorphosed) volcanic flows representing the basal portion of the (Archean) Stoughton-Roquemaure Group unconformably overlies rocks of the older (Archean) Hunter Mine Group (Jensen and Langford 1985). South of the PDFZ, weakly metamorphosed subaqueously deposited volcanic and interflow sedimentary rocks of the (Archean) Kinojevis Group are east northeast striking, steeply south dipping, south facing, and occupy part of the north limb of the east striking and east plunging Blake River Synclinorium. The PDFZ consists of a lithologically heterogenous assemblage of fault/shear bounded blocks each of which consists of variably sheared, recrystallized, and metasomatically altered rocks. Outcrop exposure within and marginal to the PDFZ is typically poor and, where data derived from diamond drill logs is lacking, the geometry and distribution of the individual fault/shear bounded blocks is to some extent a matter of conjecture. In northern Holloway and Harker Townships, the PDFZ is at least 1 km wide. Intrusive rocks near the Mattawasaga deposit include narrow syenite dikes (reported from both the Holt-McDermott Mine area (to the west) and from the Hoyle Gold Mining drilling on what once were the Ghostmount Mines claims (Satterly 1954)) and a north striking diabase dike which intrudes the deposit in the extreme southwest part of what once formed the Ghostmount Mines claims.

Dec 07, 2005 (R Degagne) - Located immediately north of (stratigraphically beneath) the magnetic basalt and often (but not always) in fault contact with it is a variably foliated (sheared) and generally heterogeneous lithologic assemblage which has been logged by Canamax Resources geologists as 'transitional alteration'. The unit typically ranges from green to yellow to mauve in color, may be locally magnetic, and is generally described to be variably carbonatized, silicified, hematized, pyritic, and sericitic. Where intensely brecciated and 'altered' (siliceous, carbonate bearing, and pyritic), 'transitional alteration' hosts a continuous anomalously auriferous zone termed the 'A Horizon' which consistently averages more than 3,000 ppb of gold over core lengths of 1-2 m. As with the southern 'transitional alteration' zone, the northern zone hosts a laterally persistent zone of intense brecciation which is siliceous and carbonate bearing. This breccia zone is termed by Canamax Resources geologists the 'main silicified zone'. Two laterally persistent, highly anomalously auriferous horizons are associated with the 'main silicified zone'. The southern of the two zones is called the 'Main' zone. The 'Main' zone: a) is hosted exclusively by the southern part of the 'main silicified zone'; b) is typically pyritic (containing locally up to 20% of pyrite); c) carries persistent but erratic anomalous gold tenors and d) has been traced along strike for about 450 m. The northern of the two auriferous zones is called the 'Footwall' zone. enveloping 'transitional alteration'. The Footwall zone consists of visible gold contained within stockworks of 0.5-2.0 cm wide quartz-calcite veinlets which are hosted by variably chloritic, sericitic, and generally nonpyritic schist; accessory amounts of arsenopyrite and tourmaline are also present.

Geologist: R Degagne
Notes: The highest potential sites for such mineralization should, at this early stage of our understanding of these deposits, probably be considered to be within and adjacent to major structural and/or stratigraphic discontinuities such as the PDFZ. Analogous lithologic, structural, and hydrothermal environments as are found near the Holt-McDermott Mine and the Mattawasaga deposit are likely to have been developed elsewhere within the Black River-Matheson area along and marginal to the three branches of the Porcupine-Destor and/or Pipestone Fault Zones (as indicated by Jensen and Langford 1985; Gupta and Johnstone 1987; and Sutcliffe and Steele 1989). Such areas should be considered to constitute high potential target areas for similar deposits of the Holt-McDermott type. Analogous regional scale stratigraphic discontinuities occur in other Archean greenstone belts; these should also be considered to be priority exploration targets for Holt-McDermott type gold mineralization.
