|Deposit Type:||Kimberlite hosted diamonds|
The Fort a la Corne (FALC) Diamond Project consists of 10 claims, in good standing, forming a land package totaling 9,445 hectares. The Company holds a 100% interest in all 10 claims. The grassroots project has had minor historic drilling testing 2 geophysical anomalies.
The main exploration and development activity in the area has been on the Star-Orion kimberlite complex of Shore Gold Inc. Shore reports an Indicated resource of 151.7 million tonnes of kimberlite, grading 14 carats per 100 tonnes.
The Fort a la Corne area is located approximately 65 km northeast of the city of Prince Albert, SK. The property is accessible all year round either from paved Highways 55 or 6, and then all-weather roads throughout the Fort a la Corne forest area.
The property lies near the northeastern edge of the Phanerozoic Interior Platform, which extends from the Rocky Mountains in the west, to the Precambrian Canadian Shield in the northeast. The sediment package in the area exceeds 600 m in thickness. The unmetamorphosed sedimentary rocks of the Interior Platform unconformably overlie metamorphosed basement rocks. These Proterozoic basement rocks have been interpreted to form part of the Glennie Domain that has been tectonically emplaced overtop of the Archean Sask craton. In the property area, the Precambrian basement is estimated to be at a depth of over 700 metres.
The major feature in the Fort a la Corne area is the existence of a northwest-trending kimberlite province covering a 50 km by 30 km area. These kimberlites have clearly defined magnetic anomaly signatures within a quiet magnetic background. Approximately 70 kimberlitic bodies have been drilled to date.
The kimberlite occurrences discovered to date generally comprise crater facies volcaniclastic kimberlite emplaced into Cretaceous marine, lacustrine and continental siliciclastic sediments. These sediments were laid down in, or along, a shallow epicontinental sea.
Continued Cretaceous sedimentation buried the kimberlites in marine sediments. In the northern part of the property area these cover rocks have largely been removed by glaciation to the level of the kimberlite. In the southern part of the property area, cretaceous sedimentary cover still exists over the kimberlite. Several phases of kimberlite have been noted and all phases are contained within the Cretaceous stratigraphy.
In February 2011, a ground magnetic survey was completed by Apex Geoscience of Edmonton, Alberta. The survey was designed to analyze existing airborne magnetic anomalies and more precisely locate and define the anomalies through groundwork prior to commencing a diamond drilling program. Based upon the 2010 review by Apex of 2004 airborne magnetic data and ground confirmation, several anomalies were selected for drill testing for kimberlite. Ground geophysics also delineated obvious basement anomalies including one very strong north-south linear magnetic anomaly which could represent a deep-seated magnetite iron formation with gold and/or iron potential or a mafic intrusive such as a differentiated gabbro with nickel potential. This magnetic feature is likely rooted in the basement crystalline rocks at a depth of between 600 metres and 1,100 metres.
In August 2012, a drill program was completed on two targets, anomalies #352 and #271. Anomaly 352 cored bedrock and potentially intersected kimberlitic sedimentary rock. Drill hole, #271 was abandoned at a depth of 147m due to drill problems associated with a thick sand and gravel package. No core was recovered. While it is possible that #271 intersected bedrock at the end of hole, the magnetic anomaly is thought to have resulted from a shallow target caused by heavy mineral concentrates (including potential magnetite) associated with an extensive sand and gravel unit.
Aside from diamond resources, three known banded iron formations consisting of interlayered bands of magnetite and hematite have been discovered and explored in the area. This is another potential exploration target.
Currently Navis Resources is planning the next phase of exploration on the FALC Diamond Projects.
