Flight control system

Tungsten alloy weights are usually used to optimize the flight control performance, such as rudder, elevator and ailerons, have a greater advantage than other traditional materials such as steel or lead.

Rotor blades

Helicopter rotor blades require the best balance. Tungsten alloy can be installed in an imbalance in the location of a single leaf in the manufacturing process, such as in helicopter balancer.

Propeller

Tungsten alloy weights can be loaded fail-safe device, in order to avoid the problem of speeding.

Inertial system

Tungsten alloy can be loaded to control the rotation of the gyro flywheel to store kinetic energy. Tungsten alloy used in this gyroscope has two main purposes:

1) To adjust the center of gravity of the triangle.

2) To adjust the beam of the laser oscillation frequency.

Happy Creek Minerals Ltd. is pleased to announce preliminary results from the first drill hole of the 2013 program on its 100% owned, 165 square kilometre Fox tungsten property. The Fox property is located approximately 75 km northeast of 100 Mile House, in the south-central Cariboo region of British Columbia, Canada.

At the RC prospect, drill hole F13-01 is a step out approximately 40.0 metres west of F12-17 (20 metres of 0.63% tungsten trioxide (W03). F13-01 is a vertical hole that was lost at a depth of 30.4 metres while in the mineralized zone due to a drilling problem. The favorable geology consists of calc-silicate and skarn which was intersected from surface, with trace tungsten beginning from 8.0 metres. Starting at 26.8 metres the hole intersected 2.72 metres grading 2.01% tungsten trioxide that is thought to be near true thickness. Other values in this interval include 0.27% zinc, 1.85 g/t silver, 0.09 g/t gold and 1.63 g/t indium. This drill site was subsequently repeated and completed through the favourable horizon and results are pending.

On the Fox property, positive values of tungsten occur in rock, stream sediment, soil and drill core in a 10 km by 3 km area. Drilling by the Company in 2007 at the Nightcrawler zone outlined positive tungsten values in multiple horizons over an area 1.5 km by 500 metres in dimension. Four kilometres to the north, four outcropping mineralized zones are named from south to north the 708, BN, RC (Ridley Creek) and BK prospects. These prospects are within a favorable target horizon (calc-silicate or skarn) spanning a distance of three kilometres and a lateral extent thought to be greater than one kilometre.

A review of drill results from the Fox property to date identified 23 intervals averaging 3.1 metres and 2.41 % tungsten trioxide that comprise a portion of the favourable horizon thickness. Drill highlights from 2011 and 2012 at the RC prospect include 7.35 metres of 1.22% tungsten trioxide, 19.4 metres of 0.82% tungsten trioxide, 11.0 metres of 0.80% tungsten trioxide, 20.0 metres of 0.63% tungsten trioxide and 24.7 metres of 0.68% tungsten trioxide. One kilometer south of the RC prospect, drilling at the BN prospect returned three intervals in hole F12-27: 4.1 metres of 1.78% tungsten trioxide, 14.8 metres of 4.0% tungsten trioxide and 24.0 metres of 0.79% tungsten trioxide including 5.8 metres of 2.01% tungsten trioxide. One kilometre north of the RC prospect, drilling at the BK prospect returned 5.0 metres of 0.68% tungsten trioxide. (Refer to Press Release dated November 19, 2012).

A grade of 2.4% tungsten trioxide contains 24.0 kg W03 per tonne of rock, and tungsten prices are around US$35.0/kg W03 in concentrates and US$42.0/kg W03 as upgraded APT (ammonium paratungstate) (1).

Tungsten is regarded as a strategic and critical metal for industrialized countries. Over 50% is used in cemented tungsten carbide to make cutting tools for the construction, metalworking, mining, oil and gas drilling industries. The balance is used for heavy alloy in applications requiring high temperature stability and density in electronic components, super-alloys, wear-resistant alloys and chemicals for various applications. Tungsten is being used and evaluated as a more effective radiation shield than lead, requiring 1/10th the thickness of lead (2). Zinc and indium also occur with tungsten at the Fox property. Indium is a rare metal used in liquid crystal applications such as touch screens and prices have risen to over US$550/kg ($5.50/gram).

The proximity to infrastructure, near surface setting, large scale and presence of high grade tungsten are thought to make the Fox property a unique and attractive new discovery in the global tungsten sector.

Mitsubishi Materials Corp. reported an increase of 16% in consolidated group net sales for the first quarter of its new financial year (2013/2014) ended June 30 to Yen 423 billion ($4.4 billion). There were reported increases in sales for cemented carbide tools as a direct result of the depreciation of the Yen, but sales of PM parts decreased due to the end of eco-car government subsidies in Japan.

This is largely due to the 13.5% rise in cement sales and a 13.8% rise in sales of the metals division. MMCs ‘Advanced Materials & Tools’ division, which includes Diamet Corp, Mitsubishi Materials Tools Co., Ltd. and MMC Superalloy Corp, continued in negative territory in the quarter with a 1.7% decrease in sales to Yen 36 billion ($369 million). However, operating profit for the Advanced Materials & Tools division increased by 15.1%.  Anyway, sales for cemented carbide were increased as a result of this depreciation.

We have been watching tungsten prices rise, pull back and rise again.

We had assumed that the market was supported by China, the dominant tungsten producer and by a forecast pullback in production from CanTung the world’s larger tungsten mines.

But tungsten prices may also indicate a return of industrial confidence and economic growth within some key manufacturing economies.

Tungsten is principally used for bits for cutting tools which are mainly used in manufacturing and heavy industry.

Manufacturers need to supply machines with tungsten carbide cutting tools as a first step before ramping up industrial production ahead of new forecast demand.

In past cycles new Chinese demand has buried the market and forced prices lower but with the market seemingly in balance we assume that new industrial demand is lifting prices.

It is possible that the US DLA and other strategic stockpile agencies are also part of the demand equation with tungsten marked as a critical metal by the major superpowers.

There are a number of new tungsten producers listed in Canada, the UK and Australia which are worth looking at.  We would avoid Malaga as its Pasto Bueno tungsten mine is now on care and maintenance.

There are no Tungsten ETFs so there is no potential for ETF sales to distort the market.
