About the project

TiGa is a New Zealand-registered company that originated as the ‘Barrytown Project’, an initiative of New Zealand entrepreneurs and investors to develop an ilmenite mine.

In 2012, they formed a company called Westland Titanium Limited. As requirements for development grew, the founders looked overseas for additional capital to fund operations. Now operating as TiGa Minerals & Metals, the company retains many New Zealand investors.

TiGa has applied for consent to mine minerals for ilmenite, garnet, zircon, gold and other minerals on privately owned Barrytown Flats farmland. The site is currently humped and hollowed dairy paddocks.

The operation involves extracting mineral ore from just below the surface of the farmland, pumping the ore to a processing plant onsite, extracting heavy mineral concentrate, and returning the unwanted soils to the extraction area. Mining will progress in strips across the site, with a maximum of five hectares under active mining at any one time.

TiGa proposes extensive processes to prevent harm to the environment, water and wildlife; and to prevent or minimise disturbance to neighbours and the community generally.

Mining process

Barrytown Mineral Project Mine

The Barrytown Mineral Project Mine will extract and process ilmenite, garnet, zircon and gold on private farmland at Barrytown Flats on the West Coast, New Zealand. The minerals will also be processed on the West Coast, adding significant value prior to export.

Using industry best practice techniques, the mine will operate on a continuous land rehabilitation process. When mining is completed, the land will be restored to productive pasture with an improved contour, and with the additional benefits of stock fencing and riparian planting of waterways and wetlands surrounding the farm. The final land levelling will ensure that the seaward side of the site remains at the same height it is now, as a defence against erosion.

Tests on the material that will be extracted from the mine, including those by Crown Research Institute ESR, do not reach the New Zealand Radiation Safety Act 2016 and International Atomic Energy Agency Transport Regulations (IAEA SSR6) to apply.

Ilmenite is used to make titanium, which is on the United States and Europe’s ‘critical minerals’ lists for its use in the production of renewable energy resources.

The minerals we propose to mine are used in the production of solar and wind power generation components, more energy efficient engines, electric vehicle batteries and other components of the high-tech energy, manufacturing and transport industries.

Titanium is also used to make medical implants including hip and knee replacements.

Ilmenite mining

  • Titanium combines with iron, aluminum, vanadium, nickel, molybdenum and other metals to produce high-performance alloys used in jet engines, spacecraft, and other high-tech products.

  • Titanium is found in many joint replacements, especially hip joints, as it connects well to the bone. It is also used in many tooth implants.

  • Most sport and recreation activities rely on titanium metal. Titanium is often found in golf clubs, tennis racquets, bike frames, skis, baseball bats, fishing rods, and hiking and camping equipment.

  • Titanium dioxide is a naturally processed powder form of ilmenite ore that is resistant to heat, protects against UV radiation, and adds brilliance in colour strength and opacity.

    It is commonly pressed into the fibres of high-quality papers to improve their whiteness, brightness, and texture. Ilmenite is added to skim milk to improve its whiteness and opacity, and even added to toothpaste, rubber, plastics, cosmetics, paints, sunscreen, and many food products for the same reason.

Garnet mining

Garnet found at the Barrytown Mineral Project Mine will primarily be used as an abrasive in high-pressure waterjet cutting equipment.

This equipment is used throughout the world in a variety of applications from cutting thick metals and stone, to thin and delicate materials such as glass, plastics and electronic components.

Garnet is also often used as an alternative to silica sand in sand blasting as it produces less dust and is much safer to use.

Zircon mining

Zircon is used for many different purposes, including ceramic tiles, in the metal founding industry, and chemical laboratories. Recent research has found zircon will play an even bigger role in future technological advances.

Zircon mined by TiGa will be sold as a non-magnetic concentrate.

Gold mining

Gold mining is an important part of New Zealand’s history. From the 1860s, gold rush followed gold rush, and thousands flocked to the fields in search of the precious metal.

Today, gold is rare and mainly used in jewellery. Gold mined by TiGa will be refined at the refinery in Greymouth.
