The Foundation of Our Business

Rocks can be"Big-Business" and it is important to be able to understand what they tell us. They host all of the metals that we use in everyday life, include gold, silver, copper lead and zinc. To find out more information about Taranis, click on the View Page.

The Quest & Remote Places

Ore deposits have been sought for thousands of years, and the most obvious deposits have been already mined-out. The quest for these deposits takes us to places that are remote. To find out more infomation on our Thor Project, click on the View Page.

The Reward!

It is still possible to find gold, silver and other metals near surface provided you have all the "right stuff". The deposits need to be trenched and drilled to develop the mineral occurrences into Resources. To find out about the Resource Taranis has developed at Thor, click on the View Page.

Experience

Many ore deposits are no longer found using the traditional prospecting methods, and require an indepth knowledge of not only geology, but other sciences including geophysics, computer science and geochemistry. To find out more infomation on our Directors, click on the View Page.

The Single Tree in the Forest

Exploration is essentially seeing through the Forest and finding a valuable tree. Sometimes the tree cannot be seen with the naked eye and requires technology that was not available to old-time prospectors. To find out how we use geophysics in Finland, click on the View Page.

Drill Baby, Drill

It is almost impossible to build a valuable Resource without using diamond drills. Diamond drilling is costly, and when done correctly it can be used to build an NI 43-101 Resource of valuable metals in the ground. To find out how we used drills to build a +1 M tonne Resource at Thor, click on the View Page.

Separating Fact & Fiction

Once a promising deposit of metals is found, it is necessary to evaluate the ability to be able to recover these metals out of the ground. There are many means to refine and concentrate ore, including gravity separation, and flotation. To find out about the recent metallurgical work at Thor, click on the View Page.

Focused Exploration

One of the main criticism of junior exploration companies by the public is the lack of focus to develop Resources on a Property. To discover more on the Resource at Thor, click on the View Page.

NI 43-101 Resources

The objective of any exploration program should be the discovery and the identification of Mineral Resources that can ultimately be classified into an NI 43-101 Resource, and ultimately mined to the benefit of the economy and the company's shareholders.

Where People Meet Challenges

Exploration is a capital intensive business, and it involves a lot of problem solving to find solutions to problems to test and evaluate the potential of an exploration property. To find out more information about our Directors, click on the View Page.

Under that Landscape is Risk

Under all the beautiful landscapes and the setting sun, lies Risk! The prudent junior mining company learns how to manage risk carefully, and not casue excessive dilution to the shareholders of the company. To find out more information about our share capital, click on the View Page.

The Tools

Exploration involves using a "toolbox" of equipment, each tool tailored to accomplish a specific objective in the exploration program. They can range from a hand-lens to an excavator, each looking to find an ore deposit. To see some images in our Gallery, click on the View Page.

The News Contrail

Exploration involves getting your hands dirty to find the answers to the questions that guide the exploration directive, and this information needs to get publicised to inform shareholders of our progress. To find out more information about News Releases, click on the View Page.

Gravity and Flotation Recovery

Describe the photo or the page it links to

Taranis completed a preliminary metallurgical assessment on samples from the Thor Project. The metallurgical tests were conducted by ALS Metallurgy-Kamloops on two separate portions of the deposit including the main historic sulphide deposit containing silver, lead, zinc, gold and copper and the new Gold Zone known as SIF. ALS has also completed Acid-Base Assessment labwork of the ore that help characterize the ores and the associated waste products.

The Bulk concentrate from test 11 had the following grades and recoveries (Note: Gold and silver grades are in g/tonne, all others are in percent):

Recoveries in Bulk Lead Concentrate
Metal Grade (% or g/tonne) Recovery (%)
Lead 51 86
Silver 2,620 65
Gold 13 56
Zinc 8 10
Copper 1.4 45

The Zinc Concentrate that had the following grades and recoveries:

Recoveries in Bulk Zinc Concentrte
Metal Grade (% of g/tonne) Recovery (%)
Lead 1.6 4
Silver 205 5
Gold 0.9 4
Zinc 58 65
Copper 0.4 11

 

Future Metallurgical Work

The metallurgical work completed at Thor is part of a larger 5 phase plan designed to permit and develop the Thor deposit (Taranis News Release Dec 11, 2013). Taranis has also been granted a Special Use Permit for the main access road to the property. The next stage in the plan is the delineation of surface Gold Zone estimated to be 24,393 m2 in area lying immediately west of the Sulphide Zone. Taranis is confident that it can build an NI 43-101 compliant gold Resource in this vicinity. Panel sampling on isolated outcrop areas have obtained results including 21.25 g/t Au over 11.45 m (Taranis News Release, September 19th, 2013), and has also yielded widespread gold values in surface grab sampling.

Gold Zone

Three separate processes to extract gold from the sample were tested: gravity concentration, flotation and cyanide leaching. Gravity recovery in the Gold Zone using a Knelson concentrator yielded 83% gold recovery to a concentrate grading 715g/tonne gold. Similarly, flotation recovered 97% gold from the feed to a concentrate grading 219 g/tonne gold. Cyanide leaching showed recoveries of 93% after 6 hours and 98% after 24 hours (ore ground to a nominal 67 micron (K80) for all tests). The positive results from flotation gravity and flotation process are encouraging as these processes are low cost and have less environmental impact when compared to cyanide leaching.

Sulphide

Rougher and cleaner tests were performed on the Sulphide Zone and utilized a conventional bulk lead flotation followed by a zinc flotation circuit, (ore ground to a nominal 97mm K80.) A limited number of optimization tests were performed, the best test results were from batch cleaner test 11 and are shown in the tables to the left.

Concentrate

The silver and gold reporting to the bulk concentrate is an ideal situation to maximize the pay-back of the precious metals in the Sulphide Zone. The copper content is not of sufficient tenor at this time to warrant recovery. It is important to note that the results are based on batch test results. There is considerable potential to increase the metal recovery of zinc to the zinc concentrate by further reagent optimization and conducting closed circuit locked cycle tests.
