The Amanda project consists of 145 claims covering 7,677 hectares. The Amanda property is located 275 km northwest of Chibougamau within the regional county municipality of Jamésie in the southern part of the Nord-du-Québec administrative region, Quebec, Canada.
The geological and geophysical data as well as the presence of many gold showings located in several locations on the Amanda property and in its environment confirm the gold potential of this project.
On August 17, 2023 Vanstar announced that it had reached an agreement with Mosaic Minerals Corporation whereby Mosaic will earn into Vanstar’s Amanda property, located approximately 65 km northeast of the town of Namaska, Quebec. Mosaic will explore the Amanda project for its lithium and gold potential.
Under the terms of the agreement, Mosaic may acquire an initial 50% interest in exchange for $1 million in exploration expenditures and the issuance of 4 million shares to Vanstar over the next three years. Expenditure commitments would be as follows:
Share issuances will be as follows:
Once the $1,000,000 in expenditures are completed and the shares issued, Mosaic will have earned 50% of the project. Vanstar would then have the option to participate in a 50-50 joint venture or allow Mosaic to acquire an additional 30% interest in exchange for filing a 43-101 resource report by the end of 2030. Mosaic will be the operator of the project. The transaction is subject to regulatory approval.
The Amanda property straddles the La Grande and Opinaca subprovinces in the center of the James Bay territory. The La Grande Subprovince is a greenstone belt dominated by multiphase intrusions of dioritic, tonalitic, granodioritic and granitic composition, injected into the volcano-sedimentary sequences of the Eastmain Group. The belt is oriented East-West and extends over approximately 300 km in length and a width which varies from 10 to 70 km. It consists of sequences of volcano-sedimentary rocks which have been released in an oceanic environment and which are injected by calc-alkaline intrusions of gabbroic to monzogranitic compositions.
The Opinaca Subprovince is made up of migmatitized paragneiss, diatexite and strips of amphibolite belonging to the Laguiche Complex. These rocks are injected by intrusions of granodiorite, granite or pegmatite from the Janin and Boyd suites. Proterozoic diabase dikes belonging to the Matachewan, Senneterre and Mistassini swarms cut across all of the region’s Archean units.
The Amanda project is located in the southeastern part of the Auclair Formation in the La Grande Subprovince. The Auclair Formation consists of a sedimentary stack essentially made up of paragneiss with an assembly of metamorphic minerals alternating with iron formations. Algoma type with facies of oxides or silicates. These iron formations correspond to concordant levels from a few meters to forty meters thick. South of Lake Beryl, the iron formations locally contain garnet, possibly resulting from metasomatism associated with the late Beryl tectonic intrusion. This intrusion corresponds to a foliated and homogeneous tonalite very rich in enclave of biotite and Andalusite paragneiss, placed at the interface between the Natel formation and the underlying Champion complex.
Before 1994, the property was the subject of various exploration works, mainly from a regional point of view, by public entities (Geological Survey of Canada, SDBJ, Ministère des Richesses Naturelles Québec) which carry out mapping programs and geophysical surveys.
From 1994 to 2009, Virginia Mines Inc. was the main player in gold exploration work on its Auclair property. The current Amanda property covers the eastern part of the former mining titles of the Auclair property. The structural study carried out in 2009 by Virginia Mines Inc. corresponds to the latest exploration work carried out from a local point of view on the Amanda property. The property has also been the subject of exploration work focused on the search for uranium or lithium in the pegmatites.
Several gold showings are listed on the Amanda property. Other evidence with a similar geological background is also highlighted within a 15 km radius to the west and southwest of the property. Mineralization consists of pyrite, pyrrhotite, disseminated arsenopyrite, and gold in quartz veins intersecting iron formations or in paragneiss. The type of mineralization is similar to the Homestake, Lupine and Musselwhite deposits.

Two types of gold mineralization could be explored for on the Amanda property. The main metallogenic model identified on the property has been recognized by Virginia Mines Inc. since 1994 and is associated with the establishment of orogenic mineralization in the iron formations of the Auclair formation. These iron formations are oxidized or silicate and strongly folded and sheared during two main deformation phases. The presence of the late tectonic pluton from South Beryl also provides a favorable context for the establishment of mineralization associated with intrusions (“Intrusion Related Gold Systems”).
