The earliest records of work and ownership of the property is from 1950 when Teck owned the property and carried out exploration. Parts of the property were later owned and explored by Cantin & Lortie (1955), R. Hinse (1956) and Bibeau and Rondeau (1965) all of who carried out geophysical and/or geological exploration programs. Also in 1951, The Lipsett Group carried out prospecting work as well as sampling on the Diana-Obatogamau, Fancamp and Haufan claims. The Mining Corporation of Canada Ltd explored the Dolbo block of claims in 1951.
In 1968 Campbell Chibougamau optioned part of the property and this company carried out an exploration program and drilled various holes. In 1974 Grandad Gold Mines Ltd. explored the Dolbo block of claims and the Ministry of Natural Resources of Québec carried out a geophysical survey over the total property in 1974 and defined six anomalies. In 1977 Patino Mines Ltd. completed a geophysical survey on the area now recognized as the Chevrier Sud zone. Some 140 claims covering the Dolbo property were claimed by SEREM in 1977. Between 1977 and 1990, this company carried out several geophysical and geological exploration programs as well as diamond drilling programs on their part of the property. In 1979 C. Talbot and A Tremblay reclaimed another part of the property.
In 1984 and 1985 Ressources Diana Ltée carried out a geophysical survey and drilling program on the Diana block of claims. Corporation Falconbridge Copper Exploration later drilled the property. In 1987 Minnova (earlier operating under the name of Corporation Falconbridge Copper, which was purchased by Metall
Mining and subsequently changed its name to INMET) became the owner of most (or all) of the claims of the properties. This company owned the properties between 1987 and 1994 and carried out the first extensive exploration programs of geological and geophysical surveys and diamond drilling. Minnova discovered the Chevrier zone in 1988 and the Chevrier Sud zone in 1992.
In 1995 GéoNova Explorations Inc. became the owner of the properties and continued exploration and study work until 2002. GéoNova carried out diamond drilling campaigns in 1996, 1997 and 2002 and prepared resource estimates and preliminary mining studies. In 2007 TAWSHO purchased the Chevrier Properties from GéoNova.

Chibougamau Area
|
| |
 |
The Chibougamau area is known for its historic mining activities that however had declined over the last few years. The human resources for a labor force, for supplies and for equipment as well as its maintenance are sufficient to sustain the exploration of the Chevrier property. The town of Chibougamau has some 8,000 inhabitants and has geological and mining firms of which the project can obtain personnel. All major services are available in Chibougamau or in Val d'Or.
The climate is a typical northern hemisphere climate with cold winters from November to April and short summers between May and September. The average temperature for the year is about -1°C.

Geology

The Chapais-Chibougamau region is located in the Superieur Province that is part of the greenstone orogene of Matagami-Chibougamau. The Archean rocks of the region are part of two distinct groups: the Roy Group, consisting mainly of volcanics; and the Opémisca Group, which is detritic-volcanic. The Opémisca Group is in discordant contact with the Roy Group. The rocks of the region are metamorphosed in the green schist facies, with the amphibole facies occurring in the proximity of some of the intrusions. The Roy Group, consists of five formations defining two volcanic cycles going from felsic to mafic, which are from the bottom to the top: The Obatogamau formation, the Waconichi formation, the Gilman formation, the Blondeau formation and the Bordeleau formation.
Structurally the regional deformation has formed isoclinal folds with an East-West orientation that is associated with the regional foliation. The deformation is also responsible for the formation of the larger structures of domes and basins in the region. From North to South the following structures are found: the Waconichi syncline, the Waconichi anticline, the Chibougamau syncline, the Chibougamau anticline, the Chapais syncline, the Dauversière anticline and the Druillettes syncline.
The Fancamp, Diana-Obatogamau and Dolbo properties are located in between the Muscocho plutons in the west, the Verneuil plutons in the south and the La Dauversière plutons in the east. The first is a post-tectonic intrusion with a dioritic to tonalitic composition while the last two are syntectonic intrusions with a granodioritic composition.
The properties of the Chevrier project cover for the main part the Fancamp fault that has a NE/SW orientation and is sub-parallel to the stratigraphy. On the Diana property, a fault with an orientation of N50°E displaces the lithologies with an apparent right-hand movement.
Economically, the region presents a number of gold anomalies that are predominantly situated near the Northeast and north-northeast faults, and especially along the Fancamp fault, where the Chevrier zone, the Lipsett showing and the B Zone of Murgor (on which property a ramp has been excavated) are located. The Lac Meston mine (also known as Joe Mann Mine) is also located in the proximity of a north-northeast fault. The area offers also a potential for massive volcanic sulfide deposits associated with the Waconichi Formation.
The underlying rocks of the Fancamp, Diana-Obatogamau and Haufan properties constitute principally of basalt's, massive concordant and discordant gabbros and of felsic to intermediate pyroclastites. Felsic dykes with quartz and feldspar phénocrystals cut these units. A granodiorite intrusion out-crops in the extreme Southwest of the property. Being part of the deformation corridor of the Fancamp fault, the region has been affected by at least four phases of deformation.
The properties can be divided into three distinct zones based on their structural characterization. The WEST zone shows a foliation of 240° and a stratigraphy varying between 030° and 010°. The CENTRAL zone is characterized by a general NE orientation of the units and the schistosity. This zone corresponds with the deformation corridor of the Fancamp fault. Finally, The SOUTH zone is characterized by a general EW foliation and by a higher magnetic signature.
