Boart Longyear has unearthed rare footage of copper exploration drilling on Bougainville, Papua New Guinea, in 1964.

The 13 minute video depicts triple tube core drilling, then a new technology, but used widely today for minimising core disturbance and maximising core recovery.  The video provides an interesting perspective on how the industry has changed over the past 50 years.

The video may be viewed via the Boart Longyear web site or YouTube.
