John Whitfield

I have been involved in the Mining Industry since 1973 when I joined Victor Products P.L.C. where I gained substantial experience in Engineering and Mining Sales. I transferred to the Victor USA location in 1982 and progressed to V.P. and General Manager of the North American Operation.

I became involved in a partnership for 5 years, then worked for an Australian outfit, Mine Site Technologies, as Eastern Regional Manager.

I have since resumed the reins of my own company and I am 100% committed to the growth and development of Longwall Mining Services (L.M.S.) as this is where I can fully utilize my experience and the relationships I have established within the Mining Industry over the last 35 years.

My primary focus has always been underground mining but I also have valuable experience in Tunneling, Hard Rock and Aggregate Industries.

I have handled import and export of distributed product, and dealt with the relevant certification and approval authorities.

The North American Market is very competitive and I have a proven track record with overseas companies in gaining market entry.

L.M.S. is interested in generating and maintaining long-term, mutually beneficial relationships with valued partners. Whether this is by distributorship or on a consultancy basis, L.M.S. offers genuine experience along with integrity.
