Rio Tinto (RIO -2.8%) may be making progress in resolving differences with Mongolia's government over the planned expansion of the Oyu Tolgoi mine, FT reports, as potential lenders extend a deadline to arrange financing for the project until the end of September.

Turquoise Hill (TRQ -2.5%), the Rio-controlled company that owns most of Oyu Tolgoi, says all parties had requested the extension of the deadline, which had passed last month, suggesting agreement over the request between TRQ and the government.

Rio and the government have battled over the costs of developing the next phase of the mine - critical for the miner as its largest new copper development, and for the country, since it will generate up to one-third of Mongolia's GDP.

Rio shares are lower, however, after mixed Q1 production results with iron ore and coal production exceeding expectations but with most other commodities falling short.
