As Phase II drilling continues, Rockcliff Copper TSXV:RCU released assays from two holes on the VMS-rich Talbot project, part of the company’s Flin Flon-Snow Lake portfolio in northern Manitoba. The company holds a 51% option on Talbot from Hudbay Minerals TSX:HBM. The standout assay drew 7.3 g/t gold and 7.49% copper-equivalent over 3.94 metres. That came from the first hole on the North Lens deep conductive plate, one of the property’s largest geophysical anomalies.
Along with assays for hole TB-015 on the North copper zone, the results show:
- 0.31% copper, 0.01 g/t gold, 0.02% zinc and 0.02 g/t silver for 0.33% copper-equivalent over 8.09 metres, starting at 463.82 metres in downhole depth
- (including 1.15% copper, 0.01% zinc and 0.01 g/t silver for 1.16% copper-equivalent over 0.32 metres)
- 1.8% copper, 0.14 g/t gold and 20.9 g/t silver for 2.15% copper-equivalent over 0.41 metres, starting at 668.61 metres
- 0.24% copper, 7.3 g/t gold, 0.88% zinc and 112.5 g/t silver for 7.49% copper-equivalent over 3.94 metres, starting at 772.45 metres
- (including 0.16% copper, 10.35 g/t gold, 0.23% zinc and 156.02 g/t silver for 9.94% copper-equivalent over 2.54 metres)
- (which includes 0.54% copper, 77.78 g/t gold, 0.01% zinc and 1,219.5 g/t silver for 73.76% copper-equivalent over 0.32 metres)
True widths weren’t available.
With downhole and surface geophysics showing that conductivity strengthens below TB-019 intercepts, Rockcliff has another hole testing the plate 250 metres deeper, closer to the plate’s centre. The North copper zone also has additional drilling planned.
The news follows assays for TB-017, released in mid-February, which featured 3.48% copper-equivalent over 16.08 metres. Talbot hosts a January 2016 resource with an inferred total for three zones:
- 2.17 million tonnes averaging 2.8% copper, 2.4 g/t gold, 2.2% zinc and 54.6 g/t silver for 133.6 million pounds copper, 165,400 ounces gold, 107.4 million pounds zinc and 3.81 million ounces silver
Reporting on another of its Snow Lake assets, last month Rockcliff announced that a surface EM survey on its recently staked Penex zinc property found a large conductive plate below the down-dip continuation of the neighbouring historic Pen zinc deposit. The company plans further exploration prior to drilling Penex this year.
Also last month, the company began airborne and ground geophysical surveys over the Laguna gold project, a former mine where 2016 grab samples graded as high as 25 g/t and 34.77 g/t gold.
With several properties comprising its Snow Lake portfolio, Rockcliff plans drilling this year on its Bur zinc project and Rail copper-polymetallic deposit, in addition to Talbot and Penex.
