From mine to farm, integrated fertiliser resource developments.

Two new Australian fertiliser developments to supply domestic and export markets. Exposure to both key phosphate and potash fertiliser industries. Strong cash backing to move through development studies.

An opportunity to participate in the establishment of an Australian phosphate and potash export industry that will also serve the local markets. Become part of the regional supply solution and reduce reliance on Middle Eastern, European and American imports.

“Centrex is now a focused fertiliser developer due for a re-rating. With a share price close to cash backing of A$ 20 million there is plenty of upside, and more than sufficient funding to complete the development studies of our high-grade phosphate and potassium nitrate projects. Infrastructure which is a key to all bulk developments crucially is already in place for both projects.”

Centrex has recently acquired Ardmore, one of the few Centrex is already well advanced in identifying customers remaining undeveloped high-grade phosphate rock for Ardmore phosphate rock in India, Australiasia, and projects in the world, located in North West Queensland. Southeast Asia. The deposit was drilled out in the 1970s with over 300 drill holes completed. The Ardmore deposit is a smaller In parallel to advancing a phosphate rock mining operation high-grade satellite deposit to the much larger Duchess at Ardmore in the near-term, Centrex continues to deposit located around 70km east, currently Australia’s progress its Oxley Potassium Nitrate Project in Western only producing phosphate mine that feeds Incitec Pivot’s Australia, 125km southeast of the Port of Geraldton. Phosphate Hill ammonium phosphate fertiliser plant. A positive Scoping Study has been completed along Centrex will move directly into a feasibility study for a with testwork to convert potassium feldspar (in the phosphate rock export operation at Ardmore, trucking rare ultrapotassic lava flow that forms the basis of the the product 90km by existing roads to the Mount Isa project) into a soluble form via a molten salt roast. The rail line for shipping out of the Port of Townsville. resultant product is water leached forming a synthetic brine, an order of magnitude higher grade in potassium Given the drilling to date at Ardmore was completed than natural brines. The brine is crystallised and the in the 1970s Centrex needs to complete validation of resultant potassium chloride is floated and reacted the historical data including further drilling to define a with nitric acid at site to make high-value water soluble JORC Mineral Resource. An Exploration Target using potassium nitrate fertiliser for the horticulture market. the historical data set has been established at 12.0 to A 155 million tonne Inferred Resource has already been 16.5 million at 28.2% to 29% P2O5. Mining conditions are very favorable with previous excavations to 10m depth defined at Oxley from just 3km of the 32km striking deposit. indicating shallow open-cut mining will be “free-dig”. All infrastructure required for the project is in place nearby including roads, rail, gas, power and even a natural brine for salt reagent held by Centrex next to the deposit.
