Thunderbird Resources is approaching the final verdict on its Slasher Flats gold acquisition in Central NSW, with the Springfield gold deposit emerging as a leading contender for early drilling. The company says the existing known high-grade hits are likely just a slice of a much bigger system that is still begging for the drill bit at Springfield. With historically limited shallow drilling having already delivered thick, near-surface gold, Thunderbird says its prospects are likely to continue to considerable depths.
