CASE STUDY: ULTRAMATRIXTM STAGETM 2 BIT-09UMXTM
LONGER LIFE, FASTER PENETRATION, REDUCED COSTS
Vital Stats:
• Achieved more than 200% increase in bit life
• Bit stayed sharp in challenging ground conditions
• Significant reduction in total operating costs
Drilling for iron ore deposits in the very remote area of Schefferville in Northern Quebec, Downing Drilling drillers face very tough ground conditions. Typical ground formations are 70% Iron Ore with bands of chert that are very hard and abrasive. The diamond bits the drillers
had been using were not providing the life they needed to be competitive, and they were not staying sharp in the hard formations.
“We are proud to say that Boart Longyear makes an amazing bit for our hard ground conditions. The 09UMX Stage 2 bits cut steady, offer long
life, and hold consistent without any abuse on our rigs.”

Other Bits 09UMXTM
The 09UMXTM bits achieved an average 200% increase in life over the other bits in the same ground conditions. In addition, the bits stay sharp, and the drillers were able to maintain the proper torque on the rigs while sustaining
a continuously sharp bit. While the drillers had been reaching an average 15 m of life with their previous bits, the 09UMX StageTM 2 bits consistently achieved a bit life of 33 m – 45 m per bit. The 09UMX Stage 2 diamond bit is now their bit of choice for all Iron Ore exploration projects.
