Tanacross Chicobi Frotet

Overview

The Tanacross Project covers 40,292 ha of prospective ground in the Yukon-Tanana Terrane, which is host to many large deposits, such as Casino, Coffee and Pogo. The property contains exposures of porphyry style mineralisation and has significant potential to host large porphyry systems in addition to epithermal, intrusion-related, and orogenic gold systems, as well as carbonate replacement/skarn systems.  This large contiguous land package was identified from regional stream sediment sampling and large scale structural interpretation of geological and geophysical data.

Location and Access

The project is located 80 kilometers northeast of Tok, Alaska.  Main access to the property is by either helicopter or fixed wing aircraft, with a 540 meter (1,770 feet) gravel airstrip in the vicinity of the property. There are numerous access trails throughout the region, with alternative winter access to the property from the Taylor Highway to the west, along an approximately 70 kilometer dirt road.

Geology and Mineralization

The geology of the Tanacross quadrangle is dominated by middle to upper Paleozoic (and perhaps older) metamorphic rocks of the Yukon-Tanana terrane, which have been intruded by Mesozoic to Tertiary granitoids. The Tanacross Project is located at the intersection between two major, terrane-scale structures: the NW trending, arc-parallel Big Creek Fault system and the NE trending, arc-perpendicular Sixtymile-Pika Fault system.  The project is underlain by regional magnetic anomaly identified from upward-continuation of magnetic data, suggesting the presence of a large buried batholith responsible for the clustering of porphyry systems at surface. Several high-level porphyry occurrences have been mapped across the property, concentrated along a predominant ridge where outcrop exposure is greatest, including the Taurus Cu-Mo-Au porphyry deposit.  The majority of the property is covered by residual soils and vegetation, concealing multiple additional geophysical targets with similar signatures to areas of known mineralization.

Exploration History

Copper-molybdenum mineralization was first discovered in the area in 1970 by International Minerals and Chemicals Corp which led to the discovery of the Taurus Cu-Mo-Au porphyry system. The USGS conducted regional stream sediment sampling for the Tanacross quadrangle in the mid 1970’s, stimulating exploration activity within the vicinity of the project area. Subsequent exploration programs focused on additional stream sediment and soil sampling and geologic mapping, identifying several porphyry Cu-Mo and banded Pb-Zn-Ag-Au prospects. In general, follow-up was limited to shallow drilling on a number of these prospects, with the exception of the Taurus system which has seen several drill campaigns (100% owned by Senator Minerals US Inc.: inferred resource of 68.3 million tonnes @ 0.275% Cu, 0.032% Mo and 0.166 g/t Au; April 2011 Technical Report).

Despite these early campaigns the area encompassed by Kenorland’s Tanacross Project remains largely untested. Additionally, recent tectonic and metallogenic studies through UBC’s Mineral Deposit Research Unit’s (MDRU) Yukon-Alaska Metallogeny Project, as well as regional campaigns undertaken by the USGS have greatly added to the understanding of structural and temporal controls on various deposit types throughout the region. Kenorland plans to investigate several identified geophysical targets undercover, and confirm historic prospects through modern geochemical surveys, to develop high quality targets for further investigation.
