STING COPPER PROJECT
Zone 2: Red Lode Deposit
Zone 3: Lode #9 Prospect
The sulphide-bearing vein which outcrops on the west bank of the Gregory River and close to the intrusive contact of gabbros and metavolcanic rocks occupies a brecciated zone in which the country rocks are cemented largely by quartz.
Assay results for channel samples were reported by Hatch (1922) as 1.63% Cu/0.3 m; 1.88% Cu/0.6 m; 6.17% Cu/1.37 m; 1.07% Cu/0.7 m and 11.4% Cu/0.68 m.
Zone 4: Chimney Cove Brook
Structurally, the area lies within a tight, gently plunging syncline, the axis of which trends through the Gregory River. The north-south trending Gregory River Fault transects the region. This major fault and associated minor faults and shearing appear to be the focus of mineralization. The mineralization occurs either massive or disseminated.
Zone 5: Chimney Cove Pond East
Harrison and Lilly (1955) reported a chalcopyrite occurrence at Chimney Cove Pond on a regional geology map. The occurrence is hosted within bytownite gabbro, anorthosite, clinopyroxenite and troctolite of the Lower Ordovician Bay of Islands Complex.
Zone 6: Creek 15 No. 2
The Humber Arm Allochthon is 200 km long and about 50 km across at its widest part. Its structural thickness is in the order of a few kilometres. Sedimentary rocks of lower structural slices of the Humber Arm Allochthon are assigned to the Humber Arm Supergroup.
A soil survey (Duval International Corp., 1981) outlined anomalous copper up to 225 ppm in soil near the contact of mafic volcanic rocks with felsic volcanics. Mineralization was located at the Creek 15 occurrence and is described as disseminated to stringer zinc copper sulfide in altered felsic volcanic rocks. Duval report values of up to 2.38% Cu over 3.1m from altered and brecciated rhyolite flows and agglomerate.
Later survey work by Noranda (1991) confirmed the mineralized zone and anomalous copper in soil. Noranda reported values from grab samples of 0.12% to 2.5% Cu, 0.23% to 1.87% Pb, 0.38% to 8.93 % Zn, 4.9g/t to 59 g/t Ag and 53 ppb to 780 ppb Au.
The combined grids show the extensive anomalous copper in soil in relation to the Creek 15 mineral occurrence.
Elevated nickel occurs throughout the grid area associated with the mafic rocks.
Multiple surveys carried out by exploration companies along Gregory River (work reports from 1991 to 2005) show strongly anomalous copper in soil associated with a basalt unit in contact with intrusive rocks.
The north-south trending basalt unit outcrops along Gregory River. Gabbro and sheeted dykes outcrop east and west of the basalt. Vein style high grade copper mineralization define mineral occurrences in the gabbro and basalt units spacially located near their contact.
A detailed view of the Jumbo Lode area highlights rock samples collected by prospectors with assay values taken from reports of work submitted between 1992 and 2006. Results show very anomalous copper / gold values.
A detailed view of the Jumbo Lode / Red Lode area shows soil sample results from work reports filed between 1992 and 2005. The results define strongly anomalous copper in soil located east of the known showings and suggests mineralization occurs in this area within the adjacent mafic volcanic rocks. The soil anomaly is open to the south.
Elevated nickel occurs in soil samples in the Jumbo Lode / Red Lode area, typical of soil overlying mafic rocks.
Rock samples collected by prospectors between 1992 and 2022 demonstrate the strong association of gold with copper mineralization in the Jumbo Lode area.
A survey described in a 2005 report highlights strongly anomalous gold in soil overlying mafic volcanic rocks near the contact with mafic intrusive rocks.
