RHT Team

A strong team with years of experience

Mike Heddon

Founding Director

Mike’s background stems from 35 years in the mining industry working for mining companies predominantly in the metallurgical and Safety fields of gold and nickel mines. Mike’s passion for mining and the realisation of the lack of available professional Safe contractors to perform quality crushing and screening and tailings storage construction saw Mike start up a successful mining contracting company in 1995. Mike exited the business in 2012 to travel. Mike returned 6 years later and realised the same opportunity to provide Safe professional services still existed and the opportunity to partner with Joe and Mark to start RHT was too exciting to ignore.

Mark Tyler

Managing Director

Mark started his career as a qualified mechanic before entering the gold mining industry. Mark held positions in the metallurgy disciplines of mining, holding positions from mill manager to project supervisor. Mark’s experience in crushing, screening and tailings storage facility construction from a client’s perspective saw Mark join Mike’s previous company in 2005 to further excel in these areas. Mark held the position of general manager in which was one of the states largest speciality contracting companies.

Mark joined RHT as managing director and is responsible for keeping our Team Safe while ensuring all of our valued customers are Safe and happy.

Joe Ricciardo


Joe has successfully owned and operated a local Perth civil contractor company Ricciardo Earthmoving since 1985 which specialises in metropolitan earthworks and earthmoving.

This well established and recognised local WA earthmoving business has a reputation with Perth’s leading residential and commercial builders as a one stop shop including earthworks, construction, waste management and plant hire. Joe’s mining contracting experiences along the way gave Joe an appetite for joining and establishing a larger company hence the establishment of RHT.
