An historic sample of Laguna gold on display at Toronto’s Royal Ontario Museum.
In the property’s first program of its kind, Rockcliff Copper TSXV:RCU has a state-of-the-art magnetometer survey now airborne over its Laguna gold project in Manitoba’s Flin Flon-Snow Lake camp. Plans call for ground-based induced polarization to follow on the 3,499-hectare past-producer optioned in September. The property forms part of Rockcliff’s high-grade Snow Lake portfolio, which includes four other projects slated for drilling this year.
A helicopter-style drone will fly “extremely tightly spaced lines with high-density ground sampling distances without the need for line-cutting,” the company stated. “It is now possible to resolve individual magnetic anomalies that were previously indistinguishable when surveyed using conventional ground and airborne surveys.”
Initial ground geophysics will consist of 65 kilometres of gradient IP, which provides advantageous economics, signal-to-noise readings, lateral resolution and depth penetration, Rockcliff added.
Grab samples from four vein systems released in January ranged from 0.01 grams per tonne up to 25 g/t and 34.77 g/t gold. The field program “discovered that the gold mineralization is structurally controlled and associated with much thicker zones of gold-rich quartz stockwork systems not previously identified or reported in historic documents,” said president/CEO Ken Lapierre. “The detailed drone magnetometer and the IP surveys will play a pivotal role in following and identifying the horizontal and lateral extent of the known high-grade stockwork systems … With this Phase I geophysical data, we will be one step closer to our first drill program on the Laguna gold mine trend and the first on this trend in over 70 years.”
Located 20 kilometres from Hudbay Minerals’ (TSX:HBM) Snow Lake gold mill, Laguna produced over 60,000 gold ounces from one vein during intermittent mining between 1916 and 1939.
Last month Rockcliff reported drill results from its 51%-optioned Talbot copper-polymetallic VMS project, with grades up to 3.48% copper-equivalent over 16.08 metres. The current program has 7,000 metres planned by spring break-up. An inferred resource for three zones totals 133.6 million pounds copper, 165,400 ounces gold, 107.4 million pounds zinc and 3.81 million ounces silver.
The company’s 2017 agenda also calls for drilling on the Bur zinc project, Rail copper-polymetallic deposit and the Penex zinc project, which Rockcliff announced staking just last week. Less than 200 metres from the historic Pen deposit, Penex has a deep-penetrating EM survey already underway.
