The Directors




Darren has held a variety of executive roles in the mining industry including Executive Director of Kimberley Metals Group, Managing Director of ASX Listed Australasian Resources Ltd as well as corporate and operational management positions at both Gold Fields Ltd and WMC Resources.

Darren, together with Ian Junk, was instrumental in identifying, securing and then funding the A$60m development of the Ridges Iron Ore Project (Kimberley, WA) sold to private Chinese interests for an undisclosed sum in 2012. Darren is a mining engineer by background with experience in both small and large operating environments – underground and open pit.




Following a successful operational career with WMC Resources, Ian founded Donegal Resources which, together with Mincor Resources, bought and re-invigorated the nickel mines, Mariners/Miitel, at Kambalda in 2000. Following this success Ian went onto to acquire a 25% interest in another Kambalda nickel mine, Lanfranchi.

He has been a non-executive director of TSX listed Brilliant Resources, ASX listed Reed Resources and most recently, Managing Director of Kimberley Metals Group, where he played a key role in the acquisition, study, project development and operational management at the Ridges Iron Ore Project, with first ore shipped within two and half years of acquiring the project.

He is currently Managing Director of Transhipment Services Pty Ltd, provider of loading / barging services to Metro Mining at their Skardon River Bauxite Project in Far North Queensland. 




Dr Tao Li is a specialist in geotechnical and mining engineering and currently the Principal and Director of TL Geotechnics & Mining. He provides technical and business advice to Australian, Canadian and Chinese mining companies. He worked for 7 years in the Chinese mining industry and for the next 23 years was an internal advisor to the Australian mining industry as an engineer, manager and group manager for organisations such as Mount Isa Mines, WMC Resources, Gold Fields Ltd and Newcrest Mining. 

In recent years he has focussed on business and project development – the Ridges Iron Ore Project being a recent success.




Mr Yauhui Liu is the owner of Dalian Bolong New Materials Co. Ltd (“Bolong”) based in Liaoning Province, China. Bolong is a large and multi-discipline company with varied interests including the operation of several metal alloy factories as well as majority ownership of the emerging Rongke Power.

Rongke is currently manufacturing vanadium flow batteries for the world’s largest chemical battery, capable of providing 200MW/800MWh and “peak-shaving” 8% of Dalian’s load when it becomes operational in 2020. Dalian is a city of 8 million in north-east China and is the country’s biggest and most active port city.





Ed is currently Managing Director of ACH Nickel, driving strategies to grow the company and its assets under ownership. Prior to this Ed headed up ACH Global from establishment and was the lead executive on both key ACH deals, namely the Foster/Jan Nickel Project (2014) and Great Southern Polymetallic Project (2016) transactions. A geologist by training, he has worked extensively in Australia and has operational experience (gold, copper and tin) in Africa, U.K and New Zealand. Prior to ACH, Ed was previously a Director at PCF Capital Group, a Perth based corporate advisory firm specialising in resource sector transactions.

In his previous roles he managed over A$300M in transaction value and advised major, mid-tier and junior resource sector companies on a range of corporate advisory, M&A and valuation assignments. Whilst at Gold Fields (2001-2008) he held a key business development role in the region reporting to the Executive Committee and was the last Chief Geologist for WMC Resources at the then 600kozpa St Ives Gold Mine, overseeing a $25mpa drill budget and discovery of over 2.0moz into reserves during his tenure (1994-2002) which covered the transition of the operation from WMC to Gold Fields ownership.

Aaron Wehrle

Exploration & Geology Manager - ACH Nickel


Aaron is a geologist with over 20 years experience in Australia, Canada and the Philippines. He has significant operational experience having worked for WMC Resources at St Ives in the Kambalda district for a number of years in a variety of direct production roles before being promoted to the site management team as Exploration Manager. In this role under new owner Gold Fields Ltd, he played a key part in the ramp up of drilling activities to dramatically increase the gold resource base in support of a new 5mtpa processing facility.  His career progressed on to resource definition and delineation responsibilities with time spent in Meliadine, Nunavut, Canada (gold) prior to returning to Australia as a Regional Geologist in the company’s Perth based exploration team. He then moved to the Philippines where he was responsible for the geological modelling and definition of the Far South East (gold-copper) Deposit based on site and in Manila.

Aaron is ACH Nickel’s Exploration & Geology Manager, having returned from a period in Manila assisting with the establishment of a geological services company.

Rusty Vincent

Field Services Superintendent


Rusty assisted ACH in 2018 on a consultancy basis but we were delighted when, in 2019, he agreed to join us in a permanent role as our Fields Services Superintendent. Prior to joining, Rusty worked in the Philippines and also for Gold Road Resources, playing the lead on-ground role in the establishment of the Gruyere Exploration Camp that facilitated the rapid and aggressive drill out of the potential orebody that was to become a 5.8Moz gold resource. Previous to this, Rusty also worked with Gold Fields alongside our Exploration & Geology Manager Aaron Wehrle, as EHS Manager for the Australasian region, focussing on that company’s exploration activities in the Philippines, China and Australia, a particular strength being on the safe work practices for remote exploration and drilling activities. 

Importantly, Rusty has significant past experience directly relevant to ACH’s Kambalda Joint Venture, having been the Geology Services Superintendent for WMC and Gold Fields at St Ives, responsible for all field activities, the drilling contract with Ausdrill Ltd and the extensive Core Farm with its historic “grave yard” of old WMC diamond drill core, so important to our present strategy to grow our portfolio with nickel mineral resources compiled in accordance with the JORC 2012 Guidelines.
