RME Geomatics delivers innovative Renegade-M drone

RME Geomatics, a world leading aerial survey services and technology company, announced earlier this month they have delivered a Renegade-M aircraft under the Canadian Federal Government Build in Canada Innovation Program (BCIP). This innovative aircraft will now undergo validation testing through the program in hopes of receiving funding to move this advanced technology from the laboratory to the marketplace.

The newly designed aircraft is a single-rotor helicopter unmanned aerial system (UAS), developed as a magnetically-quiet UAS calibrated through a proprietary procedure with an airframe-fixed commercially available cesium magnetometer. It is capable of flying in manual mode, semi-autonomous with autopilot assistance, or full autonomy for waypoint navigation. The Renegade-M can operate for a period of up to two hours, with typical flight speeds of 15 to 25 knots at an altitude of 15 to 300 metres above ground level

The Renegade-M can operate for a period of up to two hours, depending on the payload, with typical flight speeds of 15 to 25 knots at an altitude of 15 to 300 metres above ground level. The aircraft is also capable of carrying red-green-blue (RGB) camera technology to capture high resolution imagery during a survey, simultaneously with the magnetometer sensor.

The unique design of the airframe on this UAS provides a fixed magnetometer, compared to other rotary wing UAVs that sling the sensor below the airframe. This mitigates safety hazards and decreases the need for high capacity sense and avoid technologies. Additionally, by fixing the magnetometer to the airframe it does away with the challenges of compensating for the dynamic changes in the position and orientation of a slung magnetometer. It is anticipated this will lead to significant gains in data accuracy compared to other platforms.

The Renegade-M has already proven to be an effective tool to gather infrared, hyperspectral, and laser detection and ranging (LiDAR) data. Integrating the magnetometer onto this platform allows for a unique multi-payload capability and therefore the simultaneous production of multiple data sets.

PowerOre talks potential of the past producing Opemiska complex

PowerOre of Toronto has spent the winter poring over historical drill results and creating a 3D model of the past producing Springer and Perry copper mines. The geologists identified a number of wide – 20 metres or longer – disseminated mineralized drill intersections from the Springer mine.

Early in the mines’ history, operators focused on high grade veins and much of the disseminated copper mineralization in the core was not sampled. “We are keen to evaluate this aspect of the historical drilling as it pertains to our attempts at estimating an open pitable resource on the Springer mine,” said PowerOre VP exploration Charles Beaudry.

Drilling at Opemiska continues. Some of the holes will test for broadly disseminated mineralization suitable for a potential open pit mine. Others will twin the historical holes to validate earlier assays.

The Opemiska complex is located adjacent to the town of Chapais in the Chibougamau region. Falconbridge mined the Springer and Perry mines from 1951 to 1991, removing 23 million tonnes of ore grading 2.4% copper and 0.3 g/t gold.

Fission Uranium hits good grades outside high grade zone

Fission Uranium of Kelowna, B.C., is pleased with the results from three holes of its winter work program at the Patterson Lake South uranium property in the Athabasca Basin. The holes were dual purpose: to expand resources outside the modeled high grade zone and to collect geotechnical information for mine planning.

The three holes were drilled in the R780E zone. Results include hole PLS19-PW-09, which cut a 37.5-metre continuous zone of strong uranium mineralization with a near continuous 3.7-metre interval of >10,000 cps and a peak of 61,115 cps. In addition, hole PLS19-PW-10 intercepted 47.5 metres of total composite mineralization, including 3.98 metres of total composite >10,000 cps.

Fission says work will now focus on geotechnical drilling on the ring dyke and cut-off wall as well as hydrogeology and pump testing. The company hopes to complete the feasibility study and submit the environmental assessment for the Triple R deposit next year.

The deposit has 2.2 million tonnes of inferred resource at an average grade of 1.82% uranium oxide and containing 87.8 million lb. of U3O8 including the R780E high grade zone containing 48.2 million lb. of U3O8in material grading 18.39%. The 1.3 million tonnes of inferred resource grades 1.80% U3O8 and contains 52.9 million lb. of U3O8 including the high grade R780E zone containing 14.7 million lb. in material grading 20.85% U3O8.

Great Bear drills 31.4 g/t at Dixie

Vancouver-based Great Bear Resources has intercepted new gold mineralization along the fold axis at its Dixie project in the Red Lake district. The best assay was 31.40 g/t gold over 0.7 metre at a depth of 64 metres below surface.

Great Bear considers the D2 fold axis to be a significant gold control. All five of the holes recently drilled there returned gold mineralization. Two of the holes intersected multiple gold-bearing veins. These intersections may be extensions to the Dixie hinge zone vein system or may be new gold zones, said the company.

With the success of the recent drill program, Great Bear has made additional property acquisitions in the region. They include the Dedee, Pakwash and Sobel properties.

Cat 797F meets tier 4 final configuration

Caterpillar’s Cat 797F large mining truck is now available in a fuel efficient configuration that meets U.S. EPA Tier 4 Final emissions standards. Through more than 16,000 hours of successful pilot machine operation and 100,000 hours of production truck operation in Tier 4 configuration, the system has proven its ability to deliver strong performance and greater fuel efficiency compared to the Tier 2 797F in most applications.

The 797F Tier 4 Final is equipped with an exhaust after treatment system featuring selective catalytic reduction (SCR), which uses diesel exhaust fluid (DEF) to lower NO x emissions. This Cat emissions platform is proven through more than 20 million operating hours in the field. To maintain superior reliability, the 797F after treatment system uses less than 11% new content. Designed for easy serviceability with readily accessible components, the modular after treatment system is aligned with truck preventive maintenance intervals to maintain high availability.

The best-selling truck in the 363-tonne size class, the 797F is powered by the 2,983-kW Cat C175-20 engine, available with optimized fuel maps for customers focused on the lowest fuel burn, Tier 2 equivalent rating, and now Tier 4 Final. Known for delivering class-leading payload and speed-on-grade performance, the 797F delivers the same production performance in Tier 2 and Tier 4 Final configurations.

Beyond offering similar performance, the Tier 4 Final 797F reduces total specific fluid consumption costs (fuel plus DEF) in most applications. Lower fuel burn results in longer engine life and lower repair costs.

Field evaluations of the low emissions 797F included a wide range of applications, including oil sands, deep pit copper, iron ore and coal. The trucks exceeded production targets and demonstrated strong engine performance in all applications, including sites with extreme ambient temperatures as well as some with altitudes greater than 4 877 metres.

First Cobalt extends Iron Creek mineralization by 150 metres

First Cobalt Corp. of Toronto has drilled its deepest hole to date at the Iron Creek cobalt project between Challis and Salmon. The hole reached a depth of 611 metres and confirmed that mineralization in the No Name zone extends a further 150 metre down dip.

The No Name zone has now been traced to 300 metres down dip in the central area of the deposit and 400 metres in the west.

Hole ICS18-28 returned broad intercepts such as 12.0 metres of 0.20% cobalt, including 3.9 metres of 0.35% (true width). The same hole in the footwall returned 0.21% cobalt over 1.4 metres. The hole also intersected high grade copper mineralization – 1.22% over 1.0 metre (true width) – 150 metres deep in the hanging wall.

First Cobalt has arranged a $2-million non-brokered private placement of 11.1 units at a price of $0.18 per unit. Each unit consists of one common share and one share purchase warrant at a price of $0.27 each for a period of two years. The company intends to use the proceeds to support ongoing work at its refinery in Cobalt, Ont.

Eriez releases white paper on trunnion magnets

Eriez announces the release of the company’s new white paper, “Trunnion Magnet Technology Delivers Quick Payback.” According to the white paper, performance metrics collected through studies conducted among installations of Eriez Trunnion Magnets worldwide indicate a six-month to one-year payback when compared to trommel screen installations.

Eriez trunnion magnets offer savings up to $100,000 per year with a 5.5-metre mill.

This white paper, written by Eriez director of mining and minerals processing Jose Marin, explains how trunnion magnets function, highlights their performance advantages, describes retrofitting options, and provides detailed economic justification, including guidelines to assess savings potential.

A graph illustrates how kilowatt usage can be reduced by as much as 750 kW/day or 8%. According to the white paper, cost estimates of a typical 5.5-metre diameter mill indicate savings of up to $100,000 per year.

As explained in the white paper, there are hundreds of installations of Eriez trunnion magnets worldwide. This system for separating and removing balls, chips or scats in a typical ball/SAG mill operation replaces the dead weight of ball magnets with fresh ore. By effectively removing 80% or more of the worn or broken media, the trunnion magnet reduces power consumption from the mill drive and prevents expensive damage to other equipment, such as pumps and hydrocyclones.
