Héva
Abitibi-Témiscamingue is a mining region known worldwide for its gold and/or polymetallic deposits. Several mining camps have been established there, near the regional Cadillac-Larder Lake structure. The Malartic mining camp, where more than 8 million ounces of gold have been extracted, is experiencing renewed activity since the discovery of Agnico Eagle’s Lapa mine and Canadian Malartic’s Osisko project.
The estimated proven and probable reserves of the Lapa deposit amount to more than 1.1 million ounces Au (Agnico Eagle), while the Canadian Malartic project has proven and probable reserves of 6.28 million ounces Au (Osisko).
The Héva project consists of two properties (Héva Ouest and Héva Est) located between these major deposits. The properties were acquired in 2004 and are 100% owned by Arianne Resources Inc. Several gold showings are present on each of the properties, which are easily accessible by Highway 117.
Héva Ouest Property:
Location and geology :
Located between the municipalities of Rivière Héva and Cadillac, just south of the Lapa mine, the property covers an area of 167 hectares. The underlying rocks are Archean in age and belong to the volcanosedimentary Piché and Pontiac groups. The western part of the property is occupied by a granitic pluton. The Piché Group is associated with the trace of the Cadillac-Larder Lake Fault in Abitibi. From 1939 to 2002, other companies carried out exploration work on the property. However, relevant results obtained from these different programs remain difficult to verify.
Drill hole HEO-07-01 (Arianne 2007) intersected highly sheared and altered volcanics, which could correspond to the Cadillac Fault’s structure. A gold intersection of 1.26 g/t Au over 1.3 metres was obtained from a sheared basalt with smoky quartz veins containing calcite and biotite.
Further exploration will soon be carried out to test this very promising structure.
Héva Est property :
Location and geology :
Located approximately ten (10) kilometres north of the town of Malartic, the property covers an area of 1073 hectares. The rocks are Archean in age and consist mainly of Cadillac Group sediments. Some volcanics of the Blake River Group, sediments of the Kewagama Group and a narrow band of felsic intrusive rock occupy the northern and eastern parts of the property.
The Blake River Group is known, among other things, for hosting Agnico Eagle’s La Ronde mine. The mine has already produced 4 million ounces Au and has reserves of more than 5 million ounces Au.
One of the property’s claims is contiguous with the Malrobic deposit (inferred resources of 136,000 metric tons at 4.11 g/t Au), which is located at the contact between the units of the Blake River and Kewagama groups.
Gold showings
Until 2007, six (6) gold showings or intersections had been identified on the property (see table below).
In 2008, Arianne Resources Inc. drilled a hole (HEE-08-03) that intersected a conglomerate layer, which returned a gold intersection of 1.14 g/t Au over 1.5 metres.
In 2009, samples were collected during mapping and prospecting that returned values of 3.12 g/t Au and 91.2 g/t Au. The first sample was from a conglomerate near drill hole HEE-08-03. The second sample was collected over 3.0 km east of the first. It consists of a sandstone unit similar to the matrix of the preceding conglomerate.
A grid of lines was cut and geophysical surveys (magnetometer and induced polarization) were conducted to cover the anomalous sector. Interesting chargeability anomalies were defined. They will be the subject of future prospecting, stripping and/or drilling.
