Is our water at risk from the effects of mining?

During the excavation of the mine, the voids will constantly drain water from the surrounding rock and will need to be continuously pumped out.
If we look at the nearby example of Cavanacaw gold mine, where they are currently developing their underground mine, it is envisaged that up to 1290m³ (1.29 million litres) of water will be pumped out daily.

80% of Alaska metal mines polluted water

Earthworks Report: 80% of Alaska Metal Mines Polluted Water
Findings published amid push to gut public oversight and environmental review for new mines.
With the track record of the gold and metals mining industry you’d think that this would come as no surprise, but here it is in ‘black and white’.
The pursuit of short term economic benefit for long term environmental damage, much to the detriment of local populations is widespread.

 

Some shocking statistics regarding the five mines in the region include:
100% – All five mines have experienced at least one major spill or other accidental release of hazardous materials such as mine tailings, cyanide solution, diesel fuel and ore concentrate.
80% – Four of the five mines failed to capture or control contaminated mine water, resulting in water quality violations that often occurred over an extended period.
80% – Four out of five mines have been identified by EPA as out of compliance with federal laws to protect clean air or water in the last three years.
40% – Metals pollution from two mines has contaminated public lands designated as National Monuments.
80% – The Environmental Impact Statement (EIS) process at four of the mines underestimated water quality impacts, failing to predict violations of federal and state laws

Dalradian bulk sample 2014-2017

This short video tracks the 15,000 tonne bulk sample that Dalradian extracted from their exploratory adit at Curraghinalt, near Gortin. Work started in December 2014 and over the next two years the contract to extract the sample was carried out by QME Ireland.
Ore was temporarily stored in the ore shed at the Curraghinalt site, then gradually transported to a purpose built 20,000ft² facility at Foyle Port while the rest of the sample was extracted.
Moving the sample to Foyle port would have required at least 425 truck movements on the 40 mile journey- amassing a complete return run of 34,000 miles for the entire load.

Prospecting licences- what's the deal?

You’re already aware that vast tracts of land around the west of the province has had prospecting licences issued to various mining/exploration companies. These licences are issued by the Department of Finance, some for as little as only £450. Various conditions need to be met by the licensee to fulfil the terms of the licence. But what does this mean for us? There are a number of questions raised- hopefully they will be answered here-

Gold, do we really need it?

Is there any real need to mine the Sperrins in the pursuit of more gold? Is there a genuine need for it? Or is this a myth based on the ‘global economic greed machine’?Exactly how does this ‘machine’ work, what feeds it, where does the gold go? And is gold really the sound investment it is portrayed to be?Can we live without the Sperrin mined gold? Can we live without gold at all? What impact does it have in our daily lives?

Acid mine drainage

Acid mine drainage (AMD) refers to the outflow of acidic water from a mining site. In most cases, this acid comes primarily from oxidation of iron sulfide (FeS2, also known as pyrite or “fool’s gold”), which is often found in conjunction with valuable metals. Acid mine drainage is a major problem with many hardrock mines, including almost all mines where the metal ore is bound up with sulfur (metal sulfide mines). A significant number of coal mines also suffer from acid mine drainage.
The metals dissolved by the acid drainage poison downstream waters, in many cases to the point where nothing other than microbes can survive.

Curraghinalt exploratory adit

This video illustrates the explosive store, the main site compound, waste rock stockpile and the water treatment facility. The scale of this ‘exploratory operation’ is quite shocking, but it is nothing in comparison to what could be in stall for us if the planning application gets approval. The mine in Dalradian’s planning application will dwarf this operation, it will be the first of a series of mines in the Sperrins in Dalradian’s ‘mine camp’.
Perhaps most poignant thing about this video is the fact that if Dalradian had stuck to their word- none of this would be here today. It was due to be restored to it’s former ‘green field’ status, but so far the restoration process has not started, nor does it look imminent. Last year the fencing was reinforced, and several features were added to the site- hardly the actions of a company that are intending to restore the site soon. It makes you wonder though, what about the other promises that Dalradian have made? Will they be so fast to break these too?
