Looper tungsten dart rule is a very simple yet fun game to play. It is very similar to the basketball game "Horse". It may be played by any number of players and is more fun with a lot of people. This game is actually pretty boring with only two players.

For example, a player has to hit "S5" (the small wedge of the 5). With the first tungsten dart he hits the "S5". He now has two tungsten darts to set a new target. He aims at double bull ("D25") and hits it. He may now choose to sit down and not throw the third tungsten dart and leave the "D25". Let's say that, for some insane reason, he decides to try for a double 18, and misses off the board. He now loses a life and the next player now must hit "S5". The next player now gets up and hits the "S5" on his third tungsten dart. He pulls his darts and throws his first dart and hits "T20" (triple 20). Satisfied, he sits down choosing not to throw the other two darts.

If a player sets a target and all other players fail to match the target, when it's that players turn again, no throw is necessary. The player may choose to stay seated and keep the same target number. If the player chooses to risk trying a turn, the player MUST hit the target same as everyone else. If the player misses a life is lost just as if he did not set the number that stumped everyone else. It is usually wiser to just leave the number and not take the risk.

"So why do they call this 'Looper'?" The reason is that Closed loops of the numbers around the outside of the board count as valid targets! For example the loop that makes up the lower half of the number 6 is a target, however the upper hook of the 6 is not. These are written as "L", for example "L16" would meant the loop of the 16. The 8 and 18 each have two valid loops and which one is hit does matter. They would be notated as "UL8" for upper loop of the 8 or "LL8" for lower loop of the 8. As you can imagine loops are very hard to hit and are also very risky, if you miss slightly, you did not set a target number. However, if you do hit a loop, the other players have the difficulty of matching it.

Strategy: The only real strategy here is one of opportunity. If you hit the target number and have at least two tungsten darts to set a new one, try one dart at a loop. If you hit it sit down. If you don't, make sure you hit a new target even if it's an easy one with your last tungsten dart. Remember, hitting a big fat 16 and giving the next player an easy target is better than losing a life because your threw all your tungsten darts at a loop and missed or having a bounce-out with your last tungsten dart aiming for that double bull.

Looper tungsten dart rule is a very simple yet fun game to play. It is very similar to the basketball game "Horse". It may be played by any number of players and is more fun with a lot of people. This game is actually pretty boring with only two players.

The Object: To win the game you must be the last player to have any lives left.

The Scoring: Players names are written in any order down the left side of the scoreboard. Usually, a throw of one dart each at bulls-eye with the closet player throwing first and the furthest throwing last. After the first game, the first player to get knocked out plays first and so on. Three tallies are marked next to each name to indicate the number of lives left.

The Play: The first player throws one dart left-handed (or right-handed if that player is a lefty) to set a random target. Because the first player has no chance to lose a life, the random throw is used to give the second player a fair chance.

The exact wedge or bulls-eye the tungsten dart landed is marked on the scoreboard. If the dart lands in the 5 between the triple ring and the bulls-eye, you would mark "S5" to indicate the small wedge of the 5. If the dart landed in the triple 5, you would write "T5". If the dart landed in the 5 between the triple and the double rings, you would write "B5" to indicate the big wedge of the 5. If the tungsten dart landed in the double 5, you would write "D5".

The next player now must try to land a tungsten dart in the exact same wedge of the board. If that player is unsuccessful with all three tungsten darts, one life is erased and the next player has a chance.

If the player is successful in matching the wedge any tungsten darts remaining in hand may now be used to score a new target. If the target was hit with the third tungsten dart, the player pulls the tungsten darts and has all three to establish a new target. All three darts need not been thrown in a turn the player may stop at any time after the number was matched and the last dart thrown at the board is the new target. The player may not make a choice of the tungsten darts thrown, only the last dart counts. If the player misses the board with the last dart that can be thrown, a life is lost and the target remains at the previous one set.

In January 2012, Thor Mining PLC (Thor) reported Indicated Resources of 3.8 Mt at 0.29% WO3 and 0.22% molybdenum disulphide (MoS2) and Inferred Resources of 0.9 Mt at 0.25% WO3 and 0.25% MoS2 for the company's Molyhil Tungsten and Molybdenum Project, 220 kilometres northeast of Alice Springs in the NT. Reserve figures for the deposit, reported in April 2012, include open cut Probable Reserves of 1.64 Mt grading 0.42% WO3 and 0.13% MoS2. Potential development of the project was hampered by the global financial crisis and a decline in international metal prices, which resulted in the company scaling back activities. Thor had signed an off-take agreement with one of China's largest State-owned companies, CITIC Australia Trading Limited. The agreement was for CITIC to take all of the molybdenum and tungsten concentrates produced from the project, but that agreement has since lapsed. The recent increase in tungsten prices has resulted in renewed interest and in mid-2012 Thor completed a positive definitive feasibility study of the deposit, with a 4-year mine life based on current reserves. Thor has been attempting to secure agreements for off-take of tungsten and molybdenum concentrates before beginning development of the deposit. The company announced in October 2013 that it had received a letter of intent from United States-based Global Tungsten and Powders Corp. to purchase between 70 and 75% of the annual production of scheelite concentrate from Molyhil. Discussions for the remaining tungsten and molybdenum concentrates are continuing. Thor Mining has indicated it is undertaking an upgrade of its feasibility study.

Tasmania Mines Ltd (Tasmines) continued production of by-product tungsten (approximately 35 tonnes of WO3 in 2012) at its Kara magnetite mine, 35 kilometres south of Burnie in northwest Tas. The mine, which has been operating since 1977, produces magnetite and scheelite from skarn mineralisation that has replaced carbonates within Cambrian and Ordovician sediments close to the Devonian Housetop Granite. In January 2013, Tasmines released updated resource figures for the mine, including, at Kara No 1, total resources of 16.58 Mt at 49% iron oxide (FeO) and 440 parts per million (ppm) WO3, which includes Measured Resources of 10.21 Mt at 199ppm WO3, and Indicated Resources of 4.60 Mt at 714ppm WO3. In addition, updated resource figures for the Eastern Ridge Magnetite Skarn, are 6.50 Mt at 48.3% FeO and 0.10% WO3, which includes Indicated Resources of 5.24 Mt at 0.12% WO3 while at Kara North 266 and the Northern Magnetic Anomaly there is a combined Inferred Resources of 14.55 Mt at 43.5% FeO and 462ppm WO3. Ore reserves, as of January 2013, for the Kara No 1 pit comprise Proven and Probable Reserves of 13.07 Mt at 45.4% FeO and 340 ppm WO3 with 71% of the Reserves in the Proven category. Based on this reserve estimate, the company indicates a mine life of 18.4 years for the Kara No 1 pit.

In mid-2013, the Australian based company, Elementos Ltd (Elementos), acquired the Cleveland Tin project via a merger with the unlisted Rockwell Minerals Ltd (Rockwell), which previously controlled, and owned 50% of project. The Cleveland project in northwest Tas, 60 kilometres southwest of Burnie, includes the underground tin-copper (Sn-Cu) Cleveland mine which was mined by Aberfoyle Ltd between 1968 and 1986 and produced approximately 23.5 kt Sn and 9.7kt Cu. The mine closed because of low tin prices in the late 1980s. The Cleveland project also includes a large low-grade Sn-Cu tailings dam, as well as the Foley Zone tungsten deposit. The company has indicated it plans to undertake further drilling to test for extensions of tin and tungsten deposits. It also indicated in late 2013 that it had initiated a pre-feasibility study to assess the development potential of the hard rock and tailings dam tin and copper resources. The study, which is due for completion in the second quarter of 2014, will be based on a recently released (April 2013) JORC Code compliant resource for the Cleveland mine totalling 6119 kt at 0.68% Sn and 0.25% Cu, containing 42 kt of Sn. This includes Indicated Resources 4239 kt at 0.70% Sn and 0.28% Cu (contained 30 kt of Sn). A JORC Code compliant Inferred Resource of 3980 kt at 0.30% WO3, for a contained 12 kt of WO3, has been calculated for the associated Foley Zone tungsten deposit. Tungsten occurs as wolframite hosted within a quartz stock-work.

The Mount Lindsay tin (Sn) and tungsten deposit, which is wholly owned by Venture Minerals Limited (Venture), is located 15 kilometres northwest of Renison Bell tin mine and 20 kilometres west of Rosebery in western Tas. The deposit is in magnetite (Fe3O4) rich skarns within the contact aureole of the Meredith granite, which is part of a suite of Devonian-Early Carboniferous granites that are the source rocks for a number of large tin, tungsten and magnetite deposits in western Tas and on King Island in Bass Strait. The Mount Lindsay tin-tungsten deposit has, as of October 2012, combined resources of 45 Mt at 0.4% Sn equivalent with a 0.2% cut-off, 73% of the resource is in the measured and indicated categories, or 13 Mt at 0.7% Sn equivalent at 0.45% cut-off. As of November 2012, reserves included Proven Reserves of 6.4Mt at 0.2% Sn, 0.2% tungsten oxide (WO3) and 0.1% copper (Cu), and Probable Reserves of 7.3 Mt at 0.2% Sn, 0.1% WO3, and 0.1% Cu, with a contained 30 000 tonnes of Sn. The deposit also includes an iron resource. In late 2012, Venture completed a bankable feasibility study for Mount Lindsay which highlighted the long-term potential of the deposit. Highlights of the study included a 9-year mine life, a plant capacity of 1.75 Mtpa, a payback period of four years and a capital cost of just under $200 million. The study assumed tin prices of US$23 800 a tonne. The company also completed a pilot scale metallurgical program in August 2012 which demonstrated recoveries of 72% Sn and 83% WO3, as well as high grade tungsten concentrate of more than 66% WO3.

King Island Scheelite Ltd (KIS) is continuing to advance its wholly-owned Dolphin Project, located in Bass Strait on King Island, Tas. The project contains the historic open-cut and underground Dolphin mine, the underground Bold Head mine and a low-grade tailings resource, all of which are being considered by KIS for development. The deposit was discovered in 1911, and comprises tungsten and minor molybdenum mineralisation within scheelite skarns replacing dolomitic metasedimentary units of the Grassy Group. Mineralisation is related to the spatially associated Early Carboniferous granites. Originally mined as an open pit, underground mining commenced at both Bold Head and Dolphin in the early 1970s. Previous mining ceased at both mines in 1990, because of low wolfram prices. A pre-mining resource of approximately 17 Mt at 0.85% WO3 has been determined for the resource4. In 2012, KIS completed a definitive feasibility study investigating both re-treatment of the tailings and re-opening the underground mines. Outcomes of the study include a planned 10–year mine life from both underground mining and re-treatment of tailings, producing 3500 tonnes per annum (tpa) of contained WO3 in concentrate. A review of the definitive feasibility study completed in 2013 advocated shelving of the re-treatment of the tailings, and delaying underground production for several years by concentrating on an identified resource in the existing Dolphin mine open pit floor and walls. A revised study is being undertaken and is due for completion in early 2014. KIS reported in May 2013 that Indicated Resources for the Dolphin open pit remnant, Dolphin underground and the Bold Head Mine, are 0.91 Mt averaging 0.74% WO3, 4.51 Mt averaging 1.28% WO3, and 1.5 Mt averaging 0.93% WO3, respectively, for a combined total of 78.4 kt of contained WO3. Estimates of Probable Reserves for the Dolphin underground mine (excluding the open pit remnant) were upgraded in August 2011 to 2.69 Mt averaging 1.04% WO3 and containing approximately 28 kt of WO3. In June 2011, the company reported Measured Resources for the tailings at the Dolphin Mine at a cut-off grade of 0.08% WO3 as being 2.7 Mt averaging 0.17% WO3. As a result of the feasibility study review, the tailings resource is considered marginal. KIS announced in October 2013 that additional drilling at Dolphin and Bold Head to test previously recognised shallow wolfram mineralisation revealed that, potentially, it was amenable to open-cut mining.

Carbine Tungsten Ltd's (formerly Icon Resources Limited) Mount Carbine project, 120 kilometres northwest of Cairns in north Qld, contains the historic Mount Carbine deposit. The project includes a previous open-cut mine, tailings dams and low grade stockpile, all of which are being targeted by Carbine Tungsten. The tailing dams are estimated to contain approximately 2 Mt at 0.1% WO3. Carbine Tungsten opened a tailings re-treatment plant in March 2012, with an initial shipment of 1134 MTU of WO3 concentrate in late June 2012. The company announced that the grade of concentrate produced greatly exceeded expectations from the tailings recovery feasibility study. The company is hoping for final production of 5000 MTU a month from the re-treatment plant with an envisaged project life of around two to three years. Carbine Tungsten has an off-take agreement with Mitsubishi RtM Corporation Japan Ltd. Mount Carbine which was discovered late in the 19th century comprises wolframite and scheelite in sheeted quartz veins within metasedimentary rocks of the Hodgkinson Formation. Mineralisation is thought to be related to the nearby Permian Mount Carbine Granite. Recorded production3 at the mine totals 16.6 kt of wolfram as wolframite and scheelite concentrates. Mining at the deposit stopped in the late 1980s as a consequence of low tungsten prices. Carbine Tungsten completed a favourable feasibility study in July 2012 which investigated the economic viability of re-establishing the Mount Carbine tungsten mine. The study considered an open-cut, hard rock resource along with processing previously stockpiled low-grade material, which, together, would provide a 15-year project life. A result of this study was resource upgrades in June and August 2012, resulting in an Indicated Mineral Resource of 18.1 Mt at 0.14% WO3 and an Inferred Resource of 29.3 Mt at 0.12 % WO3 using a 0.05% WO3 cut-off for 48 kt of contained wolfram beneath and adjacent to the previous open-cut mine. Carbine Tungsten indicated that it considered the Indicated Resource is a Probable Reserve also, based on mining 3 Mtpa and receiving a price of US$290/MTU. The company has indicated that hard-rock mining would only commence after processing of the low-grade stockpile had begun. In September 2012, Carbine Tungsten released an Indicated Resource of 12 Mt at 0.07% WO3 for the low-grade stockpile. The company has reported a production target of 15 000 MTU of WO3 in concentrate a month from the low grade stockpile material which it suggests will have an 8-year mine life.

Vital Metals Limited's wholly owned Watershed scheelite project 150 kilometres northwest of Cairns in north Qld has, as of 30 June 2012, Measured Resources of 4.42 Mt at 0.25% WO3, Indicated Resources of 11.51 Mt at an average grade of 0.24% WO3, in addition to Inferred Resources of 4.73 Mt at 0.26% WO3, using a cut-off grade of 0.10% WO3, for a total of 50.7 kt contained WO3. In mid–2011, Vital entered into an earn-in agreement with Japan Oil, Gas and Metals National Corporation (JOGMEC), which has earned 30% of the Watershed project by co-funding a definitive feasibility study for the project. The JOGMEC interest will pass to a Japanese-owned corporation which, in partnership with Vital, will take the project into development and operation. Vital announced in July 2013 that it was extending its feasibility study to investigate tripling production rates to 3 Mt per annum, partly in response to increasing wolfram prices. The company has indicated it expects the revised feasibility study to be completed by the first quarter in 2014. Environmental approvals for the project have been granted and mining leases are expected to be granted in the near future. The Watershed deposit, originally discovered by Utah Development Company Ltd in the early 1980s, consists predominantly of quartz-scheelite vein swarms within metasedimentary rocks of the Hodgkinson Province.

The price of tungsten rose dramatically following the global financial crisis from a low of less than US$200 per metric tonne unit (MTU = 10 kilograms) of ammonium paratungstate (APT) in late 2008 to mid-2009 to reach new highs of US$480/MTU in mid-2011. This price increase reflected growth in demand and tightening of supply by China. Prices have since eased, to below US$350/MTU in early 2013, before recovering to around US$400/MTU in September 2013, which is still above the 2000-2010 long term average levels. Price increases in the second half of 2013 have also coincided with a decrease in the value of the Australian dollar. There has been continued activity at a number of Australian projects, including production at Kara in Tasmania and Wolfram Camp and Mount Carbine in north Qld.

In November 2011, the German mining company, Deutsche Rohstoff AG (DRAG) took full control of the Wolfram Camp tungsten-molybdenum project, 90 kilometres west of Cairns in north Qld, as well as the Bamford Hill tungsten-molybdenum deposit 25 kilometres south of Wolfram Camp. In February 2012, DRAG delivered its first WO3 concentrate from Wolfram Camp. The Wolfram Camp mine was discovered in the late 19th century and has a recorded production3 of 5.4 kt of wolfram, 1.4 kt of tungsten and bismuth (Bi) and 135 tonne of molybdenum (Mo). Tungsten-molybdenum-bismuth mineralisation occurs within quartz pipe-like bodies within the greisen-altered margin of the James Creek Granite in contact with metasediments of the Hodgkinson Province. The Wolfram Camp mine was officially re-opened in July 2012. In December 2012, DRAG upgraded the treatment plant allowing greater throughput, and since February 2013 the company has been producing between three and four tonnes per day of tungsten concentrate, plus an unspecified amount of by-product molybdenum. Tungsten concentrates are handled by off-take partner USA-based Global Tungsten and Powders Corp. In November 2013, DRAG announced that the Wolfram Camp mine had officially commenced commercial operations with a planned 10-year mine life. The most current resource estimate for Wolfram Camp, which was released by Planet Metals Limited in May 2010, is 1.42 million tonnes (Mt) grading 0.6% WO3 and 0.12% Mo comprising 0.78 Mt grading 0.56% WO3 and 0.13% Mo in Indicated Resources and 0.64 Mt grading 0.65% WO3 and 0.11% Mo in Inferred Resources. In November 2013, DRAG released an updated non-JORC Code compliant, estimated inventory of about 3.8 Mt returning approximately 0.4% WO3. Continued exploration is planned to further define the resource.
