Resource Information Unit (RIU) is an independent publishing business established in 1979 which specialises in the fields of mining and oil and gas.

It publishes magazines and reference books, all of which are available by subscription. The magazines are also available online to subscribers. All carry extensive advertising relevant to the mining industry. The reference books are also available on a newly-designed CD-ROM which provides quick search facilities and the ability to extract mailing lists.

They are produced by a team of experienced journalists, researchers and sales people operating out of an office in Perth, Western Australia, which houses one of the country's most comprehensive mining databases.

RIU also conducts resources conferences through its subsiduary business, RIU Conferences Pty Ltd. RIU Conferences Pty Ltd is managed by professional conference organiser Vertical Events, and has its own website, www.riuconferences.com.au.
