Alien Metals Provides Project Hancock Update

Alien Metals Ltd, a global mineral exploration and development company, provided a update on its Hancock high-grade iron ore project in the Pilbara region of Western Australia.

Strong points

  • The company recently completed the excavation of a bulk sample weighing 2378 kg of high-grade iron ore from the Ridge C resource.
  • A series of grabs taken from the bulk sample gave high quality results with an average content of 62.2% iron (Fe) in the samples and low levels of impurities.
  • Sampling indicates that the high grade material begins less than 1 m below surface.
  • The samples represent a homogeneous bulk sample at the center of the Ridge C resource and provide further confirmation of the grade and quality of the deposit.

Bill Brodie Good, CEO and CTO of Alien Metals, said: “We have continued to accelerate this excellent project and, alongside the recent third phase of the drill program, we took the opportunity to drill a sample in important bulk to advance the mining development side of the lines of work. The high nature of these results demonstrates the quality of the project and continues to give us great confidence in the planning and development process as we move forward. The team again delivered in difficult conditions and we have taken another important step in the development of the project. I look forward to updating the market on more news as we receive it.

As part of the mine development work carried out by the company and parallel to the 3rd phase of drilling, a bulk sample was taken from the central part of the C Ridge using an excavator. A sample pit approximately 7m long, 1.5m wide and to a maximum depth of 2.5m was dug on the side of the drill pad for diamond hole AM21DD004. Having the sample from this location will also be linked to the results of the diamond hole, as well as the previous RC drilling to correlate all data. After sampling, the pit was filled and rehabilitated in accordance with environmental practices.

Nine “stacks” were made from each subsequent level as the trench was dug to confirm that the correct material had been chosen for the bulk sample. Apart from the initial heap, which still returned 59.6% Fe but was found to be lower grade on site due to contamination of soil and surface materials, the remaining eight heaps were combined to produce the bulk sample giving a good representative sample of the ore.

These bulk samples are an essential part of development and mining studies as they will allow detailed metallurgical testing of the ore on a sufficient volume basis to assess various aspects that are considered in mining, such as the transportation and end-user processes to help optimize mining crushing and screening circuit design as an example.

As the company accelerates this program, this representative bulk sample of 2378 kg has been submitted to the ALS laboratory in Perth, with these first results from grab samples taken as part of the bulk sample preparation currently underway. assembly, building confidence in the quality and quality of the material and the project as a whole.

The ALS metallurgical test work has the following main objectives:

  • Understand process flow sheet requirements including DSO/enrichment characteristics to improve product qualities.
  • Potential product yields, Fe recoveries and grades.
  • Determine the physical properties of the product.
  • Process plant design parameters for ore hardness and abrasion properties. This information is necessary to select an appropriate crusher and for the maintenance of the installation.
  • Measure the variability of the ore body.
  • Generate enough representative customer samples from Ridge C.
