Black Cat Syndicate Limited (ASX: BC8) has announced a positive update on the activities at its Bulong Gold Project in WA.
The company reported that recent RC and diamond drilling at Myhree intersected several zones of high grade mineralisation.
Significant results include 3.00m @ 16.01 g/t Au from 100.50m (19MYDD006) – infill; 7.70m @ 21.38 g/t Au from 123.13m (19MYDD006) – extensional; 4.45m @ 13.92 g/t Au from 64.55m (19MYDD007) – infill; 4.60m @ 10.98 g/t Au from 184.90m (19MYDD005) – infill; 3.24m @ 9.43 g/t Au from 192.26m (19MYDD005) – infill; and 2.00m @ 13.20 g/t Au from 231m (19MYRC111) – infill.
The company announced that the initial exploration drilling at several SAM targets drilled east of the Myhree/Boundary Corridor also returned encouraging results, confirming mineralisation at a number of early stage targets.
Important results include 1m @ 13.10 g/t Au from 29m and 1m @ 4.61 g/t Au from 90m (19RERC031) (east of Virgin Dam); 3m @ 2.01 g/t Au from 60m (19RERC015) (east of Boundary South); and 1m @ 4.70 g/t Au from 51m (19RERC018) (east of Boundary South).
The company said that the Trump and Myhree Resource upgrades will be completed during the March 2020 quarter.
The Bulong gold project is situated just 25km east of Kalgoorlie in Western Australia by sealed road. Black Cat controls1 ~128km² of the Bulong Project of which ~97% of tenements are granted.
Bulong Gold project comprises of Queen Margaret Package South, Queen Margaret Package North, Porphyny Package, Woodline Package, and Anomaly 38.
Bulong has a pre-WW1 history of small scale, high grade gold production, recorded as ~152,000oz @ >1 oz/t Au, predominantly from the Queen Margaret mine.
The project’s mineral resources are located over 2.4 kilometres on the Myhree-Boundary, Trump, and Queen Margaret corridors.
Trump Corridor: The Trump Corridor lies ~700m west of the Queen Margaret Corridor and contains similar stratigraphy in an under-explored area that strikes north-south parallel to the Queen Margaret Corridor.
Myhree-Boundary Corridor: The Myhree prospect is an area of sporadic shafts sitting between the Queen Margaret Corridor and the Trump Corridor. The Boundary prospect is located 1,400m to the north of Myhree.
Queen Margaret Corridor: This corridor is 5km long and contains the Queen Margaret Mine which was mined between 1893-1912 producing ~96koz at >1oz/t Au from a high-grade shear on the contact of a porphyry.
Drilling at Myhree
The company had recently completed the RC and diamond drilling at Myhree. The diamond drilling consisted of five holes (789.9m) for metallurgical testwork (including 487m RC pre-collar). Twelve RC drill holes were also completed for 3,356m.
The holes were designed to extend and infill the Myhree Resource ahead of the March 2020 Resource update.
The company said that results from the extensional drilling show that the mineralised structures continue to the south. Infill drilling results were as expected for those areas of the Resource drilled.
Second best result intersected
Black Cat said that visible gold was found in a number of quartz veins, within a sericite and pyrite altered ultramafic host. Hole 19MYDD006 intersected 7.70m @ 21.38 g/t Au from 123.13m in an extension to the footwall lode.
Assay results reported include the following
Hole 19MYDD004: 1.43m @ 8.16 g/t Au from 199.50m; and 3.03m @ 6.38 g/t Au from 202.28m; Hole 19MYDD005: 0.98m @ 8.61 g/t Au from 165.58m; 4.60m @ 10.98 g/t Au from 184.90m; 3.24m @ 9.43 g/t Au from 192.26m; and 1.53m @ 11.52 g/t Au from 197.25m ; Hole 19MYDD006: 3.00m @ 16.01 g/t Au from 100.50m; and 7.70m @ 21.38 g/t Au from 123.13m; Hole 19MYDD007: 4.45m @ 13.92 g/t Au from 64.55m; Hole 19MYDD008: 3.97m @ 9.23 g/t Au from 71.83m; and Hole 19MYRC111: 2.00m @ 13.20 g/t Au from 231.00m.
BC8 reported that these results correlate well with mineralised zones in the Resource model and show potential upside on grade.
Drilling at Myhree-Boundary Corridor
BC8 said that as part of a broader plan to unlock the potential along the Myhree-Boundary corridor, 33 RC holes (2,990m) were drilled over new sub-audio magnetics (SAM) anomalies.
Five holes were drilled along a NE trending, high priority SAM target, 300m east of Virgin Dam. Mineralisation was drilled 200m east of Boundary South on a structural SAM target.
Encouraging assay results
The company said that numerous anomalous gold results were intersected in Virgin Dam East, including 1m @ 13.1 g/t Au from 29m and 1m @ 4.61 g/t Au from 90m (19RERC031); and 1m @ 2.73 g/t Au from 48m (19RERC029).
Results from Boundary South include 3m @ 2.01 g/t Au from 60m (19RERC015); and 1m @ 4.70 g/t Au from 51m (19RERC018).
Queen Margaret corridor
The company reported that mineralisation was also found along strike from historic shafts in the Queen Margaret corridor, 500m east of Myhree.
Results include 3m @ 1.50 g/t Au from 29m and 5m @ 1.25 g/t Au from 63m (19RERC004); 1m @ 2.74 g/t Au from 29m (19RERC005); and 1m @ 1.83 g/t Au from 38m (19RERC007).
Updates and next steps
Black Cat reported that its recent and upcoming activities would include the following
January – March 2020: ongoing extensional and exploration drilling including at Myhree, Trump, Trump North, Virgin Dam and Woodline. The company said that additional drilling is planned to further test the Virgin Dam East and Boundary South prospects. Drilling of untested SAM targets south of Myhree will be a focus during the March 2020 quarter.
January 2020: nickel assay results from Woodline.
February 2020: presenting at RIU Explorer’s Conference in Fremantle.
March 2020: quarter Resource update.
June 2020: quarter complete Myhree/Trump Feasibility Study leading to potential decision to mine at Myhree/Trump.
Black Cat’s Managing Director, Gareth Solly said: “Intersecting the second-best result to date in an extensional zone to one of the FW lodes was a highlight of this recent program. Numerous visible gold intersections and thick zones of high grade is also pleasing and reinforces our thoughts that Myhree offers a near term, high grade mining opportunity.
We were also encouraged by numerous intercepts from drilling of early stage SAM targets east of the Myhree-Boundary Corridor that were not previously drill tested. Myhree started off with similar results, so these targets will be a focus of future drilling as we look to add additional mine-ready Resources at Bulong.
SAM surveys continue to be a very effective exploration technique and highlight the exploration potential at Bulong.”
