Joutel Mining District Gold Exploration Properties
Historic Joutel Mining District
The Joutel South and McClure East Properties are gold exploration properties located along the prolific gold mineralized Casa Berardi/Joutel Structures in the Abitibi region on Northern Quebec, Canada. The Joutel South and McClure East properties are located within the Joutel Volcanic Complex (JVC) of the Harricana-Turgeon volcano-sedimentary belt, which is the most northwesterly element of the Abitibi Greenstone Belt and includes the prolific Matagami, Brouillan, Joutel and Casa Berardi mining districts (Figure 1). All commercial operations in the region had closed by 1993 with little to no subsequent gold exploration in the Joutel Area.
The Joutel South Property is at the southern underexplored extension of the Joutel felsic volcanic package that hosted both Agnico-Eagle Mines Ltd.’s (AEM-T) founding gold mines, Eagle and Telbel, which produced in excess of 1.1Moz of gold1 and a number of copper assets that have produced 244 Mlbs of copper, 116Mlbs of zinc and 52Mlbs of silver2. The McClure East Property is on the easterly extension of the Casa Berardi structural zone (south splay), which to the west hosts Hecla Mining Ltd’s (HL-NYSE) Casa Berardi Mine which has produced 2Moz and has reserves of 3.4M ounces3 and the nearby Douay Gold Deposit held by Maple Gold Mines (MGM-TSXV) and has 422,000 ounces in indicated and 2,532,000 in inferred resources4. This information from neighboring properties is not necessarily indicative of the mineralization on Orford Mining’s properties.
Both McClure East and Joutel South properties have had very limited historical testing, are easily accessible by road and are located within proven geological belts.

McClure East Gold Exploration Property
The McClure East Property contains the eastward extension of the mafics and felsic volcanic units of the JVS which hosts the previously operating Telbel Eagle Mines and straddles the contact marked by the CBDZ between the JVC to the south and Cartwright Hills Volcanic group to the North. The property is cut by major east-northeast trending diabase dykes (Figure 2).
Geological compilation results of historic drillhole data suggests that the felsic volcanic package, along with cherty iron formation which hosts the Eagle and Telbel Mines to the West, continue eastward to the McClure East Property and are present more extensively than previously indicated by the SIGEOM regional geology (Figure 2).

Recent compilation work has identified previously untested exploration targets on the McClure East Property. In 1986 and 1989 two reverse circulation (RC) glacial overburden drilling and sampling programs were completed on the McClure Property totalling 21 holes. These surveys identified EM anomalies which may be the source of strongly anomalous gold values in overburden up to 30 g/t in overburden samples which had no subsequent follow up work completed (Figure 2). View news release. These target areas shown on Figure 2 will be the focus of future work.
Joutel South Gold Exploration Property
Joutel South Property. Geological and geophysical information indicates that the volcanogenictype lithologies which host the base and precious metal mines to the north strike southwards onto Joutel South Property (Figure 2). One historical drill hole next to the Joutel South Property returned 1.66g/t over 1m and one grab sample returned 4.28g/t (Figure 2) and one hole next to the McClure East Property returned 3.26g/t Au over 0.5m. Little subsequent work had been completed historically.
Recent compilation by Orford Mining suggested the felsic volcanic package which hosts the historic Eagle and Telbel Mines to the north are more extensive on the Joutel South gold exploration property than previously indicated by the existing regional geology.
