About Dalradian

Who is Dalradian?

Dalradian Gold Limited is a mineral exploration and development company. We have been working on the Curraghinalt gold deposit in West Tyrone, Northern Ireland since late 2009. In this time, we have progressed from exploration to quantifying the amount of gold, to preliminary engineering studies, to an economic feasibility study and an environmental assessment. In November 2017, we submitted a Planning Application to build an underground mine. We have approximately 50 employees working out of our Omagh and Gortin offices and are one of the area’s largest employers.

back to top

How many other mines does Dalradian own and operate?

None. Curraghinalt is our sole focus. However, our management team has global experience in exploration, discovery, finance, development and mine operations.

back to top

Is Dalradian mining Curraghinalt already?

No. We tested mining methods as part of our exploration and produced a small quantity of Tyrone gold from our bulk sample. We then submitted a Planning Application for an underground mine and associated surface infrastructure in November 2017. Curraghinalt was designated a regionally significant project and, as such, the Planning Application is being dealt with by the Department for Infrastructure.

The Curraghinalt Project

Where is the Curraghinalt Project ?

The Curraghinalt Project is located in the parishes of Gortin and Greencastle in County Tyrone, Northern Ireland. The mine will be underground, and the proposed site for the new surface infrastructure is situated north of Crockanboy Road between Rouskey and Greencastle. We have applied to the Department for Infrastructure to retain the existing site, which is located on Camcosy Road, approximately two miles from Rouskey.

back to top

What will the surface infrastructure for the proposed mine look like?

The buildings will be placed within fields enclosed by rows of existing trees. The largest building (the process plant) will measure 58 metres wide, 102 metres long and 17 metres high. All of the buildings will be built and painted to blend in with the local agricultural buildings. There will also be a Dry Stack Facility located on the surface (see the next two questions for more details). View our 3-D animation of the project or read an article about surface infrastructure and visual impact.

back to top

What is the Dry Stack Facility?

The Dry Stack Facility will house any rock which cannot be put back underground (we estimate that about 50% will remain underground) and some of the dry stack tailings, which are like a wet sand. The Dry Stack Facility is an engineered, designed feature that will be lined, contoured into the landscape, covered in soil and progressively seeded as more material is laid down, so that it is stable and blends in with the surrounding natural landscape. We are working with research facilities on a study to determine the best soil and plant choices. Read more about dry stack tailings.

back to top

Is there a smokestack or chimney for the smelting?

The doré bars will be made in a small furnace that is fitted with ventilation, gas scrubbing and a particle capture system. The furnace will be 1.8 metres x 1.8 metres in size or smaller. Cooled air will be released through a small chimney that will be about 3 metres taller than the height of the processing plant building and similar to a house chimney. It will only be used two to three times per week.

back to top

What happens when mining is over?

When the mine closes, the surface buildings will be removed and the groundworks contoured and planted. From commencement, the Dry Stack Facility will be consolidated and engineered to ensure stability. It will also be progressively seeded starting from Year One. These activities will be set out in a Closure Rehabilitation Plan, which will be agreed by the Department for Infrastructure.

back to top

Will Dalradian be processing material from outside the area in the processing plant?

We will only process material at the plant that is sourced from the mine. Our Planning Application does not include a proposal to import ore from elsewhere.

Geology

How much gold is there?

It is estimated that Curraghinalt contains over 6 million ounces of gold. The deposit is still open in all directions (in other words, the ends of it have not been found). Read more about our resources.

back to top

How long will the gold last?

The Planning Application for the proposed mine is for a specific amount of mining that will be done over approximately 20 years. Gold deposits in Canada that are similar to Curraghinalt are in operation for decades or generations, as more gold is discovered. However, any mining in addition to what is in the current proposal would require a new planning permission.

back to top

How did you find the Curraghinalt gold deposit?

The discovery of Curraghinalt pre-dates our involvement. Gold has been known about in the area for generations. In the 1980s, prospectors noticed veins in an outcrop in the Curraghinalt Burn and they took a rock chip sample from it. This sample was analysed and was found to contain gold. Follow-up exploration, including drilling, showed that there were a number of gold-bearing veins that continued to depth. Further exploration at that time included the development of some of the tunnels that still exist today. Since acquiring the project in late 2009, we have grown the size of the known deposit more than twelve-fold through exploration, including drilling and further underground development.

back to top

How deep are the veins?

The veins extend from the surface to at least one kilometre in depth. Part of the planning application is to allow for some additional exploration to allow us to investigate the extent of the system.

back to top

Why are veins different widths?

The veins are fractures in the rock that have “healed” with quartz, carbonate and other minerals such as gold. Like any natural system, variability is the norm.

back to top

How long are the veins?

The current extent that has been tested is about 2.3 kilometres long. However, the Curraghinalt vein system has the potential to grow. We hope to explore more of the deposit and that is why we are applying for an underground area for exploration.

back to top

How much tunnelling have you done underground?

We added 959 metres through the recent underground exploration programme to the pre-existing 710 metres.

Jobs

How many jobs will the proposed mine create?

The project will create at least 300 jobs during construction (which will last approximately 18 to 24 months) and at least 350 permanent positions during operations. Read more about our future careers.

back to top

Are you recruiting?

We are actively accepting expressions of interest for future positions, but we will not be able to hire a full workforce for construction and operations until planning permission is granted. You can submit your expression of interest at Future Careers , which will assist us in designing our training programmes.

back to top

Can local people get jobs?

Yes, there will be jobs at the proposed mine for a full range of skills – from mechanics and lorry drivers to IT, geologists, engineers and administrators – as well as jobs in health and safety and environmental monitoring and management. Some jobs will require specific qualifications or training, such as university or college diplomas, but for others, short-term educational training and/or on-the-job training will suffice. A full list of jobs can be found at Future Careers.

back to top

Can training be acquired in the next few years to be ready for employment when you get planning permission?

Yes. We have engaged with South West College to implement training programmes that meet the skill requirements needed to work on the project. We have invested in career planning through the development of a number of existing local staff. This is something that will continue throughout the planning process. Our internship programme has already provided invaluable work experience to university students in relevant disciplines. Wherever possible, we have hired those students as full-time employees. We will be able to expand this programme significantly when the mine becomes operational.

back to top

Are there any training courses in local colleges for working underground?

We are working with South West College on training programmes, including a programme to train future miners.

back to top

How much will a worker at the mine earn?

The average salary at the mine will be £40,000, nearly double the average wage in Northern Ireland.

back to top

Will there be permanent jobs or will you use temporary contracts?

We will use primarily permanent full-time contracts during operations. We want to be a flexible employer that looks after its workforce. The issuing of permanent full-time contracts is a part of our retention plan.

There are two phases to the project: the first is construction and the second is operation of the mine. We estimate the construction of the project to take 18 to 24 months. Operations are expected to last approximately 20 years and could be longer, depending on the success of future exploration.

back to top

What is the minimum age for working at an underground mine?

Underground mine workers must be 18 years of age or over.

back to top

Will there be summer work for students?

Yes. We hire student interns each summer and plan to continue throughout construction and operations. To apply, fill out the Future Careers form.

back to top

Environment

The proposed mine will be located in an Area of Outstanding Natural Beauty (“AONB”). How will the AONB be protected?

The proposed site faces away from the AONB and the main spine of the Sperrin Mountains. Mitigating visual impacts has been a major part of our environmental assessment and studies. Many features of the site lend themselves to reducing visual impact, including existing mature trees and natural hollows. The buildings will be in keeping with the local rural area and will be painted green to blend in with the landscape. Rehabilitation of the site will be ongoing throughout operations and completed when operations are complete with removal of all buildings.

back to top

How will you ensure safe cyanide management?

The use of cyanide at the site to will be approved and regulated by both the Health and Safety Executive and the Industrial Pollution and Radiochemical Inspectorate at the Northern Ireland Environment Agency. Cyanide will be delivered to the site in solid form as briquettes and will be stored and used only in areas with concrete flooring within the processing plant. All tanks and pipes that contain solutions with cyanide will also have a secondary containment that has a capacity of 110% of the maximum volume to be stored.

A comprehensive Cyanide Management Plan will be developed, agreed upon, implemented and independently audited. It will include commitments to transport, unload, store, use and destruct cyanide in accordance with best practices.

We are committed to following stricter guidelines than required by law by becoming a signatory to the International Cyanide Management Code. You can find out more about what this means at http://www.cyanidecode.org/about-cyanide-code.

back to top

How can you prevent problems like the Aberfan coal disaster in Wales?

The Aberfan coal mine disaster was caused when unconsolidated material, dumped in a chaotic and unplanned/unregulated manner, was subjected to heavy rainfall, which caused the material to become unstable.

The proposed gold mine is very different from a coal mine and will not have waste tips. Instead, we will use dry stack tailings that are engineered to ensure stability. The material is consolidated, progressively seeded and monitored. As applicable, current legislation also requires periodic geotechnical assessments by qualified specialists.

back to top

How will you protect our rivers from an environmental disaster?

Similar to our existing exploration site, mine contact water, including rainwater run-off from the proposed infrastructure site, will be captured and then directed to a state-of-the-art water treatment plant. The purpose of the plant is to ensure any discharge water meets or exceeds performance criteria set for it by the Water Management Unit of the Northern Ireland Environment Agency (NIEA). Both we and the NIEA will monitor the outlet water quality to confirm compliance. The water management ponds on site will have an engineered lining system and have appropriate capacity to accommodate a one-in-1,000-years storm event. The ponds will be constructed by excavation and will not rely upon impoundments for water containment. Read more about water protection.

back to top

How is groundwater protected and how can you be sure my well won’t be contaminated?

During operations and for some time following closure, groundwater movement in the vicinity will be towards the mine and not outwards towards any wells. Similar to a quarry, water entering the mine will be captured in sumps and sent to the surface for water quality treatment and/or for use in the processing plant.

All material types to be retained or sent back underground have been subject to prior characterization and will also require laboratory verification testing during operations. Taking into account the proposed mining, backfill and closure strategies, the results from materials characterization tests have been modelled to predict long term water quality in the mine workings after closure and when these eventually flood. Thereafter, known surrounding groundwater seepage rates have been used to predict long term groundwater concentrations adjacent to and downstream of the workings.

Based on this assessment, pollution of groundwater receptors, including wells will not occur.

Our Environmental Statement presents current regional background groundwater quality as a benchmark to compare against future monitoring data. Water quality monitoring within the mine, and in wells installed directly around the mine perimeter, will be used during operations to both progressively confirm actual groundwater quality is as predicted and that agreed limits are not exceeded.

back to top

How is the Dry Stack Facility going to be reinstated?

The Dry Stack Facility will be contoured to fit in with the existing hills around the site, covered in soil and seeded in stages. It is designed to blend in with the surrounding landscape.

back to top

Will animals be able to graze on the site?

Yes. This is done at a number of reclaimed mine sites in Ireland and worldwide.

back to top

Is the mine and its buildings going to be a blight on the landscape?

Mining will take place underground and therefore will not be visible. Surface infrastructure was planned to minimise visual effects, including the use of existing visual barriers such as trees and new plantings. We also plan to utilise the existing hills and valley to hide the buildings. Additionally, we have designed the height and colour of the buildings to be similar to agricultural buildings in the local area. Watch our 3D animation to get more detail of site layout and appearance.

back to top

What about dust and noise?

There are strict legislative limits relating to dust and noise, and we have designed the project to meet those requirements. For example, we will use water suppression and plantings to control dust. To ensure noise control, we will have trees, sound berms and sound barriers.

back to top

How can trees and barriers stop the noise and view of an industrial facility?

We will use a combination of trees, topography and berms to help mitigate visual and noise effects. For example, the road from the portal to the processing plant will have a long hill between it and the valley below. This will decrease the noise of the trucks and block them from view. Another example is the placement of part of the Dry Stack Facility in a natural hollow so that its height will be reduced.

These components and design measures will not stop noise and view of the mine altogether, but will greatly reduce it.

back to top

How will traffic be managed at the mine?

As part of our planning process, independent experts examined the impact to local communities of a rise in the number of vehicles on the road network, especially around the villages of Greencastle, Rouskey and Gortin. Processing the ore on site radically cuts down on the amount of traffic coming to and leaving the site on a daily basis.

During the construction and operation of the mine, workers will car-share and use park and ride services to attend the site. Shifts will be staggered to avoid traffic build-up at particular peak times, such as during school runs.During operations, there will be an additional 60 cars per day over a 12 hour period.

For more details, see our traffic article.

back to top

How will you source water for the site?

Rain falling on the site will be captured and stored for use along with water that seeps into the mine workings underground and is pumped to surface (dewatering). Water will be recycled as much as possible in the processing plant to minimise water usage.

Economic Benefits

What are the main social and economic benefits of the proposed mine?

  • Total employment boost of some 1,000 jobs
    • Direct employment of at least 350 permanent jobs
    • 455 indirect jobs at our suppliers
    • 165 induced jobs from increased spending in the area due to higher salaries
  • Average salary of £40,000, nearly twice the average salary in Northern Ireland
  • Stemming the outflow of young talent from the West of Northern Ireland
  • Training and skills development, including course development with South West College and internships
  • More than $1 billion in spending to build and operate the mine, creating supplier opportunities in West Tyrone and Northern Ireland
  • Brexit-proof project – you can’t move a mine!
  • 2.4% reduction in Northern Ireland's trade deficit
  • £360 million capital investment over the life of mine
  • £4 million community fund commitment

What is the Feasibility Study?

The Feasibility Study outlines the economics of the proposed mine, including employment and taxes. The full report was released in January 2017.

back to top

Why is there a longer mine life in the Planning Application than in the Feasibility Study?

The Planning Application, which is a document intended for government, community and other local stakeholders, was prepared by technical experts to comply with regulatory requirements and environmental and planning regulations. However, it is different from the scientific and technical information in the Technical Report, which was prepared by “qualified persons” in accordance with Canadian securities law requirements of NI 43-101 and depicts a mine life of 10.3 years and anticipated production of 1.36 million ounces of gold. The two documents have different purposes and audiences.

The project as described in the Planning Application is based on the Indicated and Inferred Mineral Resources, thereby increasing the mine life to 20-25 years and showing anticipated production of approximately 3.5 million ounces of gold. The Planning Application also correspondingly depicts the likely significant effects of a longer mine life.

back to top

Will cash and profits generated be transferred out of Northern Ireland?

Some of the cash generated will be transferred out of Northern Ireland but the majority will remain. The economics of mining at Curraghinalt were determined through the Feasibility Study. A majority of the costs of mining and processing the gold will be spent in Northern Ireland. Typically, the biggest costs are labour, fuel and electricity. Taxes and royalties will also be paid. Some money will be reinvested for exploration to increase the life of the mine and to support operations, including new equipment and replacement parts each year.

What is the Crown Estate?

Please visit the Crown Estate's FAQ page for more information.

back to top

What taxes will Dalradian pay?

Dalradian will be paying the same taxes as any other business in Northern Ireland.

back to top

Will Dalradian be required to post a bond to ensure the cost of closing the mine is covered?

Yes, a financial guarantee is a requirement to receive planning permission.

back to top

What is gold worth?

Gold is currently worth approximately £1,000 per ounce. The price of gold can vary daily and is influenced by world markets.

back to top

What is the Tyrone Fund?

The Tyrone Fund was established by Dalradian in December 2015 for the benefit of the local community. The Company makes contributions to the fund on an annual basis. A committee meets twice per year to decide on applications for funding. In the Planning Application, Dalradian has committed to an enlarged fund once operations begin. Read more about our current and future support for community projects.

back to top

Operations

How many drill rigs work on the project?

This varies, but we have had up to seven on the surface at any one time. During the underground exploration, as many as three drill rigs were operational underground at one time.

back to top

Will you still need to employ drill rigs once the mine is operational?

Yes. During the life of mine, we will need to drill around the project – on the surface and underground – to further define the deposit.

back to top

What is backfilling?

Backfilling is placing materials (rock and/or tailings) into voids that we have excavated underground. Backfilling enhances our ability to mine the full mineral deposit by maximizing underground stability. Backfilling also minimises the material that is stored on the surface and reduces our footprint.

back to top

What is paste-backfill?

Paste-backfill is a mixture of material from the mill (floatation tailings and detoxified tailings) with cement. It is used to fill voids underground created by mining.

back to top

How are explosives managed?

Explosives are highly regulated by both the Health and Safety Executive and the Department of Justice as to transport; amounts stored, where and for how long they’re kept; record keeping; use; and storage. We adhere to the guidelines set by the regulators. During operations, explosives will be stored and used underground.

back to top

Mining and Processing

How will Dalradian mine for gold?

The veins that hosts the gold will be drilled and then blasted. These are narrow veins that are typically less than 1 metre wide (i.e., less than the width of a kitchen table). The veins are tens of metres apart. It will then be brought to the surface via a tunnel. The road between the portal and the processing plant will have a berm (planted earth mound) on the downhill side to minimise visual and noise disturbance for local residents.

back to top

What is the ore stockpile?

There will be a crushed ore stockpile at the proposed mine – it will be a covered, dome-like building where ore is stored after crushing and prior to on-site processing in the mill.

back to top

What happens to the ore when it leaves the stockpile?

At the proposed mine, the ore will be transported/conveyed to the processing plant, where it will undergo grinding and processing to separate the gold from the rock.

back to top

How does the processing work?

The mined rock is brought to the surface and the portion of the material that has economic levels of gold (known as ore) is put through a multi-step process to recover the gold. The material that does not have economic levels of gold is kept underground or placed on the Dry Stack Facility.

The ore is reduced in size by crushing and is then further mixed with water and ground in a mill to the size of coarse sand. This water and ground rock mixture is then directed through a process called flotation, in which the minerals of value are separated from the material that is devoid of mineralization; the latter is called tailings. As much as possible, the tailings are placed underground, with the remainder directed through a filter press to remove water. The tailings from the filter press are placed on the Dry Stack Facility, which can be reclaimed and sculpted into the landscape.

The minerals recovered in flotation that contain gold, called a concentrate, represent approximately 11% of the total material that enters the flotation process. This concentrate is further ground and pumped into a series of bunded tanks, where it is mixed with a cyanide solution. The cyanide solution dissolves the gold. The gold-rich liquid is mixed with activated carbon. Activated Carbon for this process is simply carbonized coconut shell in which the gold is deposited. The rock and water mix containing residual cyanide, now also devoid of gold, undergoes cyanide destruction and is solidified with cement and a portion of the dry stack tailings underground, to fill up areas that have been previously mined. The gold on the activated carbon is now removed with a heated solution and the carbon is reused. The gold solution is passed through cells that use electricity to transfer it onto steel plates. The plates are rinsed to yield a gold sludge, which is brought to the furnace, where it is melted down to form a doré bar. The bars are then sold to a mint or some other facility that can further refine them.

back to top

When does the ore become gold?

The ore doesn’t become gold. Ore is a word used to describe the rock that contains economic quantities of gold. The processing separates the rock from the gold and concentrates it. It doesn’t even look like gold until it is made into a doré bar. We don’t see any visible gold underground because it is very fine.

back to top

Where will the soils that will be used for reclamation be stockpiled?

The soils removed to allow for construction of the mine buildings and the Dry Stack Facility will be temporarily placed in piles on site, closest to where they will be used to facilitate replacement and ongoing reclamation.

back to top

How is the Dry Stack Facility reclaimed?

The Dry Stack Facility will be progressively built up layer by layer, gradually covered with soil that has been sourced from the site and then seeded. A conceptual Closure and Rehabilitation plan for the site was submitted to regulators as part of our Environmental Statement. The conceptual plan (which is subject to approval by the Department for Infrastructure) details a range of measures which will leave the site safe and secure, and rehabilitate it for use as either farming and/or heathlands. Read more about rehabilitating the site.

back to top

Planning Application Process

When will the mine be operational?

We submitted our Planning Application to build a mine in November 2017. The mine cannot be constructed before the authorities grant planning approval. It is estimated that the planning process (review of the application, consultation and likely a Public Local Inquiry) will take a few years. Read more about the planning process.

back to top

What is the time frame for building and mining?

Construction is expected to take 18 to 24 months. After construction is completed, mining is expected to take place for 20-25 years. The mining could be extended, depending on exploration success, but would be subject to additional planning permission.

back to top

What can I do to support the Planning Application?

If you support our plans to build a mine and believe it will be economically transformative for West Tyrone while respecting the environment, express your support to the Department for Infrastructure (“DfI”). You will want to include the specific reasons you support the application. You can do this via our Build a Support Letter tool at http://dalradianni.com/creating-over-350-well-paid-jobs-in-county-tyrone/.

What if Dalradian or the project are sold?

In the event of a sale of the project or company, the acquirer would have to adhere to the planning and environmental terms and conditions set by DfI as well as any contracts or agreements that Dalradian has made. They will also have to comply with the requirements of our planning permission to operate the proposed mine.

back to top

Will there be other mines locally? Will Dalradian be able to process material from other locations at the Curraghinalt Mine?

There may be other gold deposits discovered in this area in the future. At this point, it is impossible to predict whether they would be economically viable. Any future mines would also need to move through the planning process before mining could begin. Our current Planning Application only includes processing material from the Curraghinalt gold deposit (i.e., no material may be brought from off-site for processing).
