Entirely ionizing radiation by some definitions; completely absorbed by the atmosphere A variety of solid-state and vacuum devices have been explored for use in different parts of the UV spectrum. Many approaches seek to adapt visible light-sensing devices, but these can suffer from unwanted response to visible light and various instabilities. Ultraviolet can be detected by suitable photodiodes and photocathodeswhich can be tailored to be sensitive to different parts of the UV spectrum.

Mining over the next 20 years consisted of sinking the Main Shaft and development of a small open cut. Additional shafts were excavated between and and then again between and by various parties. Sincein excess of holes have been drilled at Dargues Reef.

The identified resources and reserves within the Project were last updated in Juneand stand at 1. The study concluded that the Project would support a viable underground mining operation.

Since the initial study a Definitive Feasibility Study and an Environmental Assessment has been conducted and the potential for an even more robust project identified.

The project represents the first new gold mine to be approved in NSW since Lake Cowal more than ten years ago. The Dargues Gold Project will comprise an underground gold mine declinea run-of-mine ROM Pad, temporary waste rock emplacement, crushing facility, gold processing plant, tailings storage facility and associated infrastructure.

The application area for the Project infrastructure covers an area of approximately ha of freehold land owned by the Company. Extraction of waste rock and ore material from the Dargues Reef deposit using underground sub-level open stope mining methods.

Construction and use of surface infrastructure required for the underground mine, including a box cut, portal and decline, magazines, fuel store, ventilation rise and power and water supply.

Construction and use of a tailings storage facility, a water management system and a site access road, ancillary infrastructure, including soil stockpiles, core yards, internal roads and tracks and surface water management structures. Transportation of gold concentrate from the Project Site to customers via public roads.

The underground mine and infrastructure designed. The operation will mine ,t pa using conventional long hole open stope mining methods via a decline. The plant is designed to extract half the gold via a simple gravity process and also produce a sulphide concentrate, containing the other half of the gold.

The end result is a state of the art, modern, environmentally friendly gold processing facility designed on the principals of ecologically sustainable development that will boast a very small surface footprint. Diversified Minerals, which held a The offer would comprise 1c a share to be received through an equal capital reduction and 1.

Unity chairperson Clive Jones pointed out that throughout the second half ofUnity had initiated an internal assessment of its strategy in light of the decision to cease production at the Henty gold mine in lateand to not proceed with a cyanide processing plant at the Dargues gold projects.

The Unity board has unanimously recommended that shareholders accept the offer, which was subject to a number of conditions, including shareholder approval, an independent expert evaluation of the offer, and other customary conditions.

The transaction was not subject to any financing, due diligence or regulatory approvals, other than those associated with implementing the scheme of arrangement. An overwhelming majority of about submissions to the NSW Planning and Environment Department including from government agencies, objected to the proposal.

Most objectors, including Eurobodalla Shire Council and specialist scientists, believed cyanide waste in a huge tailings dam above the South Coast's water catchment would find its way into the drinking catchment for up topeople.

I am very happy, thankful everybody pulled together. We were resolved that this was not right, I think it is a great outcome. It didn't have community support. The risk of a cyanide spill upstream was the last straw for the orchardist, who previously battled supermarkets, poor seasons and uncertainty.

Author and downstream resident Jackie French said four years ago she was prepared to give the miners the benefit of the doubt. But pollution in Majors Creek and the cyanide proposal had angered her.

Now Ms French is relieved, but angry she has lost so much time writing submissions fighting the mine, when she could have been writing children's books. Dr O'Loughlin said data in an environmental assessment to support modifying the mine underestimated rainfall and overestimated evaporation.

Rainfall data used to calculate monthly inputs to the tailings dam, claimed by Unity Mining to be from Braidwood Weather Station, were incorrect and significantly different from rainfall statistics published by the Australian Bureau of Meteorology, Dr O'Loughlin said.

As well as withdrawing the application to modify the mine, Unity's chief executive Andrew McIlwain, has resigned. Mr McIlwain had previously assured the community cyanide would not be used, but later said it was not dangerous in mining operations.

In a statement on Tuesday, Mr McIlwain said: We will, however, continue to seek approval for the relatively minor modifications in the application," he said. Unfortunately, I won't be at the helm to see the project to fruition," said Mr McIlwain.

The miner wanted to expand the tailings dam from nine to 16 hectares. Concerns of heavy rain washing pollutants downstream arose earlier after Unity pleaded guilty in the Land and Environment Court to polluting Spring and Majors Creek three times in Start studying Chapter Solid and Liquid (Hazardous) Waste.
