Flying Over South Quarry
One area of tungsten mineralization (scheelite) is a quarry referred to as the 'South Quarry' in the northern part of the property. At this location, the scheelite occurs in veins cutting metasediments. Access to this quarry and the entire property is excellent. A paved provincial highway transects the property from north to south.

South Quarry is a high priority tungsten property with lithium potential, located in east-central Newfoundland. The property covers an area of 1,925 hectares. The property contains tungsten bearing quartz-mica-feldspar pegmatitic veins and tungsten bearing calc-silicate layers. The tungsten mineralization occurs as scheelite.

Tungsten bearing veins occur in the northern region of the property including at a quarry called the South Quarry and an adjacent smaller quarry and in multiple areas north-northeast of these quarries including a new discovery during 2019. Great Atlantic confirmed high-grade tungsten mineralization in veins in rubble and bedrock at the two quarries during 2015. Eleven rubble grab samples exceeded 5% WO3 (3 of which exceeded 10% WO3). A 20 cm long channel sample along a 15 cm wide vein in the small quarry returned 2.96% WO3 while a grab sample from a 0.25-meter wide vein in the South Quarry returned 11.94% WO3. A Qualified Person supervised the 2015 sampling and verified the sample data. The samples (and lab-inserted blank, standard and duplicate samples) were analyzed by ALS Canada Ltd. in North Vancouver, BC (ALS Canada Ltd. is independent of Great Atlantic Resources). Tungsten analysis was by lithium borate fusion and ICP-MS finish with some samples re-analyzed by XRF. Host rocks are meta-sediments. Multi-element analysis of 2015 rock samples (at ALS Canada in North Vancouver by Aqua Regia – ICP-AES / ICP-MS) revealed some samples anomalous for lithium (up to 297 ppm Li).

A new discovery of tungsten bearing veins was made during the 2019 exploration program northeast of the South Quarry. The quartz-dominant veins were located a historic trench / stripped area. The program and sampling were supervised by a Qualified Person. Multiple samples returned anomalous values for tungsten. The highlight was a sample returning 1.10% WO3. The samples (and lab-inserted blank, standard and duplicate samples) were analyzed by ALS Canada Ltd. in North Vancouver by lithium borate fusion and ICP-MS finish. A Qualified Person supervised the 2019 sampling and verified the sample data.

Tungsten mineralization is reported in the southern region of the property, reported in narrow (<1m) calc-silicate layers (source: Newfoundland and Labrador Dept. of Natural Resources Mineral Assessment Reports). A qualified person has not verified this mineralization.

Granite intrusions are reported peripheral to the property. Great Atlantic management speculate tungsten mineralization on the property to be related to buried granitic intrusions.


 

 


WHY TUNGSTEN

Tungsten has unique properties:
• extremely hard and dense
• has the highest melting temperature of any metal
• extremely resistant to corrosion and does not break down or decompose
Tungsten is an indispensable material in most industrial applications.
