Tungsten Mining (ASX:TGN) has followed up yesterday's Initial Public Offering on the ASX with the announcement that drilling has commenced on its flagship Kilba Tungsten Project in Western Australia. 

Tungsten says it is concentrating on rapidly evaluating and developing the site, which hosts a high grade scheelite deposit with potential to support a mining project. 

The diversified miner holds a 100 per cent entitlement to a mining lease within the Kilba, and has completed the first phase of its drilling program, comprising 8 diamind core holes. 

Tungsten says the drilling program, alongside its admission to the ASX, represents a significant milestone towards becoming a developer. 

Tungsten Mining listed on the ASX yesterday, closing the day at $0.205.

At present, the demand of tungsten concentrate becomes worse that suppliers are not confident with market in near future. Today, mainstream 65% tungsten concentrate price based on Ganzhou focuses on ￥115,000.00/mt, real transaction price could as low as ￥112,000.00/mt, more than 60% scheelite concentrate quotation based on Hunan is ￥113.000.00/mt.

According to the analysis of Chinatungsten Online, the situation of supply exceeds demand is hard to reverse in short time. Some tungsten concentrate suppliers are hurried to get cash that they are more willing to ship. However, the demand of downstream users, few deals can be seen. Under this situation, price range goes narrow that delivery price shows its downward trend. Chinatungsten Online expects, tungsten concentrate prices will keep weak, but the price will hold above ￥110,000.00/mt.

Sergei Belousov and his colleagues at Moscow’s Kintech Lab in collaboration with scientists at the GE Global Research Center in New York state have discovered an application for photonics crystals that can improve light emitting efficiency of tungsten. This may lead to a complete redesign of the light bulb at we know it.

Belousov and his team wanted to find out whether a nanostructure of tungsten can be engineered to create a photonic visible light-emitting infrared light. The team studied the theoretical properties of nanoscopic tungsten log piles and spheres embedded in another medium. They tested their data after creating a tungsten photonic crystal to measure the amount of emitted light occurring at different frequencies. What they discovered is that the structure emits less infrared light while having 15% efficiency – much higher than standard bulk materials.

Why is this important? Belousov and team’s research indicates improvements on the technology are possible. However, more research and testing are needed to determine whether the use of tungsten in light bulbs can achieve widespread use. Compact fluorescent bulbs match the light output of a 100 Watt tungsten bulb using less than 30 Watts, and LED bulbs can by less than 20 Watts. Belousov and his team may have their work cut out, but they believe they have a chance.

The final £13m has been secured to revive tungsten mining on the edge of Dartmoor.

Australian-based company Wolf Minerals now has £140m for the project in Devon, although the final £13m is yet to be signed off by shareholders.
