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.

Still adding to its approximately 45,000-hectare property package in Manitoba’s Flin Flon-Snow Lake mining camp, Rockcliff Copper TSXV:RCU acquired the Penex zinc project by staking. Located less than 200 metres from the historic Pen deposit, the property already has a deep-penetrating EM survey underway prior to drilling planned for this year.

All of the historic deposit’s lenses dip towards the new acquisition’s northern boundary, with at least one zinc-bearing lens dipping onto the property, the company stated. An historic, non-43-101 drill hole on Penex assayed 4.04% zinc-equivalent over 7.57 metres, including 6.73% over 2.64 metres.

Bore hole geophysics confirmed that conductivity continued downward within the property, strengthening at depth in an area untested by drilling, Rockcliff added.

The new turf “underpins our commitment to acquire properties either by staking or acquisition that have significant metal potential within trucking distance to milling facilities in this world class base and precious metals camp,” said president/CEO Ken Lapierre.

Rockcliff has work planned this year on four of the other properties that comprise its Snow Lake project. Two weeks ago the company reported assays from its 51%-held Talbot copper-polymetallic VMS property, where Phase II drilling continues. A resource calculated last year for three Talbot zones brought an average copper-equivalent grade of 5.5%. The inferred category totalled:

  • 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

Rockcliff’s 2017 agenda also calls for work on its Bur zinc project, the Rail copper-gold-silver property and the former Laguna gold mine. Debt-free, the company currently has about $1.5 million on hand.

In another February 28 announcement, the Fraser Institute rated Manitoba second to Saskatchewan worldwide in the 2016 survey of 104 mining jurisdictions. “Competitive tax regimes, efficient permitting procedures and certainty surrounding environmental regulations and land claims have vaulted Saskatchewan and Manitoba to the top in the eyes of miners looking to invest,” said Kenneth Green, a co-author of the study.

Rockcliff Copper reports assays, geophysics from Flin Flon-Snow Lake

February 16th, 2017

by Greg Klein | February 16, 2017

As drilling continues on its Talbot property in Manitoba’s Flin Flon-Snow Lake camp, Rockcliff Copper TSXV:RCU reported promising assays and geophysics on February 16. The copper-polymetallic VMS deposit forms part of the company’s approximately 45,000-hectare Snow Lake portfolio. Rockcliff holds a 51% option on Talbot from Hudbay Minerals TSX:HBM.

Hole TB-017 on the deposit’s main lens, “in an area void of drilling,” returned the following assays:

  • 0.93% copper, 2.73 g/t gold, 0.65% zinc and 15.23 g/t silver for 3.48% copper-equivalent over 16.08 metres, starting at 774.37 metres in downhole depth

Within that interval were two overlapping intercepts:

  • 0.35% copper, 4.02 g/t gold, 0.48% zinc and 13 g/t silver for 3.77% copper-equivalent over 8.74 metres, starting at 780.63 metres

  • 1.7% copper, 4.11 g/t gold, 0.34% zinc and 19.76 g/t silver for 5.2% copper-equivalent over 3.51 metres, starting at 786.94 metres

True widths weren’t available.

Drilling now focuses on a vertical-dipping 300-by-600-metre conductive plate recently discovered below the deposit’s north lens. EM has also found a larger conductive plate below the main lens, which could represent down-dip continuity of the lens.

Additionally, the survey found a much deeper but larger flat-lying target called the west Talbot deep conductive plate, measuring about one kilometre by one kilometre.

“Most of the larger mines in the camp have multiple stacked lenses that were initially identified as conductive plates,” remarked president/CEO Ken Lapierre. “We remain greatly encouraged not only by the consistent high metal grades and increased size potential of the deposit, but by the metal potential of the untested stacked conductive plates proximal to the deposit.”

The 7,000-metre program continues until winter break-up, targeting the north lens plate and the plates below the north copper zone, 2.5 kilometres north of the deposit.

Talbot’s January 2016 resource detailed an inferred category for three zones totalling:

  • 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

Rockcliff has work scheduled on three other Snow Lake properties this year. The past-producing Laguna gold project has a high-res magnetic survey planned, while rigs will keep busy on the Bur zinc project and Rail copper-polymetallic deposit.

The company currently has about $2 million in the bank.

Plucking the high grades

Rockcliff Copper plans a busy year for its expanded Flin Flon-Snow Lake turf

by Greg Klein

Rockcliff Copper has a busy year planned for its expanded Flin Flon-Snow Lake turf

This year’s drilling will keep core shacks busy on at least three Rockcliff properties.

 

Grade is king to Ken Lapierre, so he proudly describes his company’s portfolio as “the best of three worlds—high-grade copper, high-grade zinc and high-grade gold”—the highest-grade unmined deposits in Manitoba’s Flin Flon-Snow Lake region, he adds. But the Rockcliff Copper TSXV:RCU geologist/president/CEO also emphasizes the properties’ location. “They’re beside excellent infrastructure, in a world-class mining camp, a mining-friendly jurisdiction and a politically stable country. You really can’t get any better than that.”

Ken Lapierre considers Rockcliff’s portfolio to
hold the camp’s highest-grade unmined deposits.

Active in the region for about a decade, the company began by going after non-core assets of Hudbay Minerals TSX:HBM. The pace of property acquisitions picked up late last year, leaving Rockcliff with about 45,000 hectares.

Included are two copper-polymetallic deposits with resource estimates, four zinc deposits with historic, non-43-101 estimates and a gold project on the site of a former high-grade mine. The properties sit within trucking distance of two Hudbay plants, one for gold, the other for base metals.

Four projects have work planned this year.

Now underway at Talbot is a program recently increased from 6,000 to 7,500 metres on a project that’s undergone over 13,000 metres in the last 18 months. Lapierre describes it as a “high-grade VMS copper deposit with a high-grade gold tenor.” A January 2016 resource for three zones showed an inferred total of:

  • 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

The average copper-equivalent grade comes to 5.5%, Lapierre points out.

“Talbot has room to grow because it’s open in all directions and there’s a host of conductive plates that could represent more deposits,” he says.

Besides hoping for expansion along strike and at depth, Lapierre sees possibilities for new discoveries on the approximately 12,000-hectare property.

“The attractive thing about this deposit is that it looks and feels like all the other large deposits that became large mines in this camp. You have a series of geophysical anomalies close together with base metals present. As well as three zones of mineralization that create the deposit, it has additional geophysical conductive plates along strike and at depth that have never been tested. So we wouldn’t have to go far to make a new discovery.”

The current campaign’s expected to last until March. That would bring Rockcliff past the halfway point of its 51% option with Hudbay. Lapierre sees Talbot’s resource update possible by year-end.

Although Snow Lake is known as a VMS camp, “in reality it started as a gold camp,” Lapierre points out. That brings to mind another object of his enthusiasm, the former Laguna gold mine acquired last September. “If this property was in Timmins it would have had tens of millions of dollars spent on it.”

One vein mined in the 1930s averaged 20.5 grams per tonne, producing 60,000 ounces. “The attractive thing about Laguna’s gold veins and stockwork systems is they’re a lot wider than we originally thought,” he continues. “The oldtimers followed narrow, high-grade veins running over an ounce to the ton…. The reality is these high-grade veins are associated with quartz stockwork systems. We sampled an old trench where five metres averaged about 7.5 grams per tonne. Back then that would have been waste, but today it’s not. There’s a series of these vein systems and they’re associated with a long structural fault system.”

Grab sampling late last year suggested a trend covering over six kilometres on the 3,499-hectare property.

There’s multiple veins but the last time it was drilled was in 1944 and the last time it had any decent science was never.—Ken Lapierre, president/CEO of Rockcliff Copper

“There’s multiple veins but the last time it was drilled was in 1944 and the last time it had any decent science was never.”

That changes this winter, as a helicopter-style drone flies a high-res magnetic survey over the property. The plan is to “outline and identify potential structural traps where gold likes to hang its hat,” Lapierre explains. “Then we’re going to follow with a surface induced polarization survey which will give us hotspots. The gold that’s on this property is associated with sulphides, so the IP survey will find where there’s an accumulation of sulphides.”

Back to VMS deposits, another 2017 drill priority is the Bur zinc project, optioned from Hudbay in September under a four-year, 100% earn-in. The 3,979-hectare property came with a 2007 resource that Rockcliff considers historic and non-43-101:

  • indicated: 1.05 million tonnes averaging 8.6% zinc, 1.9% copper, 12.1 g/t silver and 0.05 g/t gold

  • inferred: 302,000 tonnes averaging 9% zinc, 1.4% copper, 9.6 g/t silver and 0.08 g/t gold

The deposit remains open in all directions. “If our first phase drill program is successful, we’ll put that into a 43-101 resource which would be done by the end of 2017 as well.”

The near-surface Rail deposit
remains open in all directions.

This year also calls for four to six holes totalling about 2,500 metres at the Rail deposit. In 2010 Rockcliff compiled a resource with an indicated category showing:

  • 822,000 tonnes averaging 3.04% copper, 0.9% zinc, 0.66 g/t gold and 9.25 g/t silver for 55.09 million pounds copper

“Rail has huge room for growth,” Lapierre says. “The deposit is still open along strike and at depth, it has a large untested geophysical plate below the deposit and for the most part it’s only been drilled down to about 250 metres.”

Among other projects with historic deposits is the 1,662-hectare near-surface MacBride zinc deposit. The December purchase came with a 1977 non-43-101 estimate of:

  • 1.82 million tonnes averaging 8.8% zinc, 0.3% copper, 0.1 g/t gold and 4.5 g/t silver

A 1.5% NSR in the Tower T-1 copper deposit might bring in over $1 million a year, Lapierre says. Rockcliff optioned its 70% stake to Akuna Minerals, which has a feasibility study scheduled for December. Lapierre hopes to see Akuna begin production by 2018.

As for more acquisitions, “we feel we’ve plucked the best there is to pluck in this camp,” he says. “But you always look because the minute you stop looking you eliminate opportunities to find a mine.”

Meanwhile the 2017 agenda calls for exploration on four properties, with drills turning on at least three.

Rockcliff Copper reports 5.9% copper-equivalent over 5.6 metres, expands Manitoba drill program

Rockcliff Copper reports 5.9% copper-equivalent over 5.6 metres, expands Manitoba drill program

Buoyed by new assays from Phase II drilling, Rockcliff Copper TSXV:RCU has increased its Talbot drill program from 6,000 metres to 7,500 metres. The company holds a 51% option on the polymetallic copper project, part of its 45,000-hectare Snow Lake holdings in Manitoba’s Flin Flon-Snow Lake mining region.

Talbot’s latest results, from hole TB-016, show:

  • 2.64% copper, 2.94 g/t gold, 1.67% zinc and 23 g/t silver for 5.9% copper-equivalent over 5.63 metres, starting at 849.38 metres in downhole depth
  • (including 4.61% copper, 5.08 g/t gold, 2.09% zinc and 39.12 g/t silver for 9.9% copper-equivalent over 2.8 metres)

  • 0.64% copper, 0.24 g/t gold, 1.04% zinc and 5.6 g/t silver for 1.4% copper-equivalent over 3.39 metres, starting at 865.77 metres

Earlier this month Rockcliff reported assays from hole TB-012:

  • 1.2% copper, 0.92 g/t gold, 0.24% zinc and 10.2 g/t silver for 2.1% copper-equivalent over 12.57 metres, starting at 840.62 metres
  • (including 2% copper, 1.94 g/t gold, 0.32% zinc and 20.03 g/t silver for 3.9% copper-equivalent over 5.3 metres)

True widths weren’t provided.

TB-012 confirmed “continuity of the main lens in an area void of drilling along the deposit’s north boundary of the main lens,” the company stated.

A January 2016 resource estimate for three zones at Talbot showed an inferred category totalling:

  • 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

Rockcliff describes Talbot as “similar to that of present and past-producing base metal deposits of bi-modal volcanoclastic rocks in the Flin Flon-Snow Lake greenstone belt.”

With mineralization open in all directions, the program will “focus on resource expansion of the deposit as well as drill-testing geophysical plates/anomalies recently discovered from the resurveying of historic drill holes,” said president/CEO Ken Lapierre. The property has year-round road access.

Last week Rockcliff released grab samples grading up to 25 g/t and 34.77 g/t gold from the Snow Lake project’s Laguna site, which has state-of-the-art airborne magnetics planned. The company’s other Snow Lake assets include a 100% interest in the Rail deposit, with an indicated resource of 822,000 tonnes averaging 3.9% copper-equivalent, and non-43-101, historic estimates for four other deposits.

Rockcliff has about $2.5 million in the bank and no debt.

Rockcliff Copper releases gold samples, plans state-of-the-art airborne at former Manitoba mine

January 16th, 2017

by Greg Klein | January 16, 2017

Calling it the “first systematic, scientific exploration program on the property in over 70 years,” Rockcliff Copper TSXV:RCU has a high-resolution airborne survey planned for its Laguna gold property in central Manitoba’s Flin Flon-Snow Lake camp. Twenty-five recent grab samples from four vein systems on the former mine site brought grades ranging from 0.01 grams per tonne gold up to 25 g/t and 34.77 g/t. The results indicate a trend covering over six kilometres within the 3,499-hectare property, the company stated.

A magnetic survey conducted by a state-of-the-art helicopter-style drone will allow the program to “economically fly extremely tight line spacings with high-density ground sampling distances without the need for linecutting,” Rockcliff added.

“It is now possible to resolve individual magnetic anomalies that were previously indistinguishable when surveyed using conventional ground and airborne surveys—perfect for structurally controlled gold exploration targets like that at the Laguna property.”

Located 20 kilometres from a Hudbay Minerals TSX:HBM gold mill now on care and maintenance, the Laguna project comprises part of Rockcliff’s 45,000-hectare Snow Lake portfolio. Included are 43-101 estimates for the Talbot and Rail copper-gold-zinc-silver resources, as well as historic, non-43-101 zinc deposits.
