"recent discovery of potash??"" This deposit of Potach about 20km south of Udon has been known for a long time.. The original Environmental Impact study was done over 10 years ago.. The Canadian Co. that had the concession to mine sold it to a Thai consortium a few years ago and the project has not moved forward to my knowledge. If there is an Iron deposit in Udon province, I'd wager it is on the western edge in the hilly/ridge areas. Wikipedia says this about the Potash mine concession"
"Asia Pacific Resources, a wholly owned subsidiary of Italian-Thai Development PLC, owns the concession to the Udon Thani potash mines and plans to develop them. According to press reports, Udon Thani has enough potash to mine 2 million tonnes per year for 25 years. Potash is one of the main components in fertilizer.
Unconfirmed reports that the Government of China is negotiating to buy the rights for Udon Thani from ITD (Italian-Thai Development PCL)"
Ah, here you go.. There is Iron Ore is in Loei province, so if it is also in Udon province I'd wager it's on the western border of the province in the hilly areas....

"Detailed Selling Lead Description
We can offer the Iron Ore 62% Fe of Loei province, Thailand North Eastern origin for serious inquiries only." IRON ORE HANDLING
The design of the processing circuit is designed to feature a jaw crusher equipped with a rock-breaker followed by a two stage crushing and screening operation with horizontal washing screen to produce both lump and fines 0-50 mm size or as client's request.
Capacity at 1,000 Mt per day and plan for 4,000 mt
Sufficient stockpiles of ore will be maintained at the processing facilities to allow for uninterrupted trucking/barging to Ayutthaya/Sriracha port.
Specifications;
Iron as Fe: 62 % min : Volumatic test method
Sulfur as S: 0.02%-0.08% max :
Phosphorus as P: 0.02%-0.10% max : Based on ASTM E278-01
Silica as SiO2: 2% to 5.0% max : Gravimatric test method
Aluminum as Al2O3: 0.98%-3.5% max : ICP test method
Specific gravity from 4.0 to 4.5.
Moisture content: Humidity at 105 deg.c on received basis 8%, Rainy season Max.10%.
Sizes: Fine and Lump
Fines are defined as iron ore with the majority of Individual particles measuring less than 10 millimeters diameter. Conversely, lump is iron ore Majority of individual particles measuring more than 10 Millimeters diameter. Iron ore lumps varies from + 10 mm to + 75 mm.
Fe Content: Iron of as high-grade as possible is required because an increased of 1% Fe in the burden increased the productivity by 2% and decreased the coke rate by 3%. In the Dee Laa Mining, the range of the Fe content in iron ore lumps is 60.2% to 66.5%.
Silica: 1.5% decreased of silica causes reduction in the slag volume of 65kg per ton of pig iron. Increase of 100-kg slag per tonne of pig iron raised fuel consumption by 40 kg of coke per tonne of pig iron. In the Thailand Plants, the range of silica in iron ore lumps varies from 2.6% to 5.0% (max.).
Alumina: If the ore is high in alumina, the fluidity of slag is affected. It should not also be too low. In the Indian Plants, alumina content in the ore varies from 3% to 3.5% Generally.
Phosphorus should not exceed 0.10%
DISTANCE ADVANTAGE:
The closest distance to China, Korea and Japan than other iron ore deposits, the transportation of the iron ore to China and Japan requires shorter time than other exporters. (Approximately 2,600 Nautical miles, India approximately 4,000 Nautical miles, Australia approximately 3,600 nautical miles, and Brazil approximately 10,000 nautical miles to China)
