2003-2004 Field Campaign
A new crop of data acquisition projects

In order to promote the remarkable mineral potential of Québec, the Ministère des Ressources naturelles, through Géologie Québec, pursues with consistency and determination its efforts to acquire new geoscience data throughout Québec.

Field projects carried out by Géologie Québec were targeted in the wake of a vast client consultation conducted to help develop triennial plans for all of Québec’s territory. These plans are useful to constrain which geological settings are considered to be particularly prospective for new discoveries.

The results of fieldwork conducted by Géologie Québec crews during the summer 2003 throughout Québec will be exclusively unveiled next November, during the Québec Exploration 2003 event. Until then, here is a sneak preview of the new crop of data acquisition projects planned by Géologie Québec for the summer 2003.

Location of projects 2003-2004

Three-year plan for the Abitibi and the Baie-James region

Established in conjunction with the mining industry, Géologie Québec’s three-year plan for the Abitibi and the Baie-James region for the 2003-2006 period will cover all field projects carried out in the Abitibi region starting in the summer 2003. This work includes the Lac Olga project, in the Baie-James region. This project had initially been scheduled for the previous three-year plan covering the 2000-2003 period. The new plan also includes the Grenville Front project east of Chibougamau.

Baie-James region

In the Baie-James region, two inventory surveys will be conducted to link the geology of the Matagami and Chibougamau areas, and to better understand the Grenville Front east of Chibougamau. A metallogenic component is included in each of these projects. A "Quaternary" component is also planned to complement the Grenville Front project east of Chibougamau. Furthermore, a metallogenic study of the Mistassini basin, launched in 2002, will continue this year with the cooperation of the Institut national de la recherche scientifique (INRS) and the Mistissini Geological Resources Centre.

Abitibi

Southeast of Lebel-sur-Quévillon, an inventory survey along the Grenville Front will be completed by a metallogenic study in the adjacent Urban-Barry area. As in the Chibougamau area, a Quaternary component is also planned to round off this project. In the Rouyn-Noranda area, two complementary metallogenic studies will detail the mineral potential of the Blake River Group. Finally, a metallogenic study undertaken last year along the Destor-Porcupine fault in the Duparquet area will be completed.

From now on, 3D modelling of geoscience data will be systematically integrated to regional metallogenic syntheses in the Abitibi region. In partnership with the Unité de recherche et de service en technologie minérale (URSTM) of the Université du Québec en Abitibi-Témiscamingue and Mira Geoscience, two new digital products at the leading edge of technology will be developed this year. The first concerns a particularly prospective segment of the Destor-Porcupine fault for gold deposits, in the Duparquet area. The second will present the unified geology of the main mining camp in Québec, the Doyon-Bousquet-LaRonde district.

Far North

This year, Géologie Québec will complete the mapping coverage at 1:250,000 scale of the Far North west of Ungava Bay and the Labrador Trough. Two geological surveys will be conducted in the Kogaluk Bay (34N) and Lac Minto (34F and 34G) areas, along the eastern shore of Hudson Bay. The MRN will also continue its cooperative effort with the Geological Survey of Canada, in the search for kimberlite indicator minerals. This search was very successful over the last two years, and has renewed interest for diamond exploration in the Far North.

Based on consultations conducted with our clientele, we have also developed a three-year data acquisition plan for 2003-2006. This plan provides for synthesis work covering stratigraphy, geochemistry, structure, metamorphism, and mineral deposits for this vast area, as well as mapping of the area located between the 54th and 55th parallels in 2004 and 2005.

Grenville

This year, geoscience work in the Grenville basically involves the completion of a mapping project in the area north of Mont-Laurier (31O/02), within the scope of a synthesis of the Central Metasedimentary Belt, and the conclusion of a study of tectonic nappes in the Pontiac area. A study of the nickel, copper and platinum group element potential is also planned for the Mauricie region. Finally, a lake sediment survey is planned in the Côte-Nord area north of Baie-Comeau (22F-K-N). The latter will be conducted in partnership with mining companies and regional agencies, as a preliminary phase leading to regional mapping to be conducted over the next few years.

Consultations were conducted over the past year, in order to develop a three-year action plan for the Grenville. We are currently conducting a comprehensive review of previous work, in order to pinpoint gaps in our knowledge of the Grenville. We will then be able to define priorities to address over the coming years. This plan will be submitted in the fall 2003, for application in 2004-2007.

Appalachians

Géologie Québec continues to implement its three-year action plan for the Appalachians. We will begin phase 2 of the plan this year, with two projects to update the geology in the southern (22B/01 and 08) and central (22B/16) Gaspe region and with a metallogenic study in the central Gaspe. These studies are specifically focussed on base and precious metal deposits in sedimentary settings in the south, and in a volcanic environment in the central part. We will also complete a ground gravity survey of the Gaspésie region this year, launched in 2002 in partnership with SOQUEM and Hydro-Québec.

Industrial minerals

A survey of sand and gravel resources in the Saguenay–Lac-Saint-Jean region will begin this season. This project should last from three to six years, according to the human and financial resources allocated for the project. A two-year survey of the peat resources in the Bas-Saint-Laurent region will also be launched this year. A number of visits of peatlands throughout the province will complete the ice peat study. A few industrial mineral deposits, namely slate and limestone occurrences, will be examined within the scope of a synthesis study conducted in Southern Québec. To complete the rare metals project, potential assessments of a few areas of interest will be conducted. Finally, the gravity survey undertaken last year in the Gaspésie region will be completed.
