SYDNEY -- Fallout from the deflating mining boom continues to claim more victims, with resources exports likely to be significantly lower and another downgrade likely on the way.

Resources exports in 2012/2013 are expected to fall to around $190 billion, down from the previous forecast of $209 billion, according to the Resources Minister Martin Ferguson. The phase of high prices associated with the mining boom is over. Recent announcements of job losses by Xstrata Coal and BHP Billiton (ASX: BHP.AX) in Queensland provide an indication of the impact of lower prices on profit margins for our miners.

A request for a trading halt by mining services company, MacMahon Holdings Limited (ASX: MAH.AX) over the weekend, citing deteriorating financial performance and increased uncertainty about the outlook for new construction work, provides another example. Only last week, NRW Holdings (ASX: NWH.AX), a mining services company working on Fortescue Metals Group's (ASX: FMG.AX) iron ore projects in the Pilbara region, was forced to cut its revenue forecasts for the next financial year, after Fortescue announced plans to slow expansion of its iron ore mining.

The mining services sector is now pretty much unloved, and more companies are expected to report lower forecast revenues, due to decisions by the miners to pull back their capital expenditure and slow their projects down. However, not all mining services companies provide the same services to the same clients. As an example, Monadelphous Group (ASX: MND.AX) provides much of its services to the oil and gas industries, which are less affected by the fall in commodity prices. In fact, companies servicing the LNG industry should do well, with several multi-billion projects under development around Australia. LNG projects can typically take several years to develop.

The Foolish bottom line
For those investors prepared to do their own research, several mining services stocks may have been marked down by the market by association, despite earning only a small percentage of total revenues from services to miners that are cutting back on capex. Likewise, some companies service gold and other mineral miners, which have not seen the falls in commodity prices like iron ore and coal, so work for them is unlikely to drop off.
