4. NORTHSPAN RC Drilling 101
• Rock chips,not drill core
• HIGHACCURACY, RELIABLE SAMPLES
• Large sample compared to core drilling
• Capable in difficult ground conditions
• Requires little or no water
• highpenetration rates
• VERY EFFECTIVEDRILLING METHODFOR
0-200M Holes
5. Canada - 5% RC vs 95% Core
• As a whole the Canadian corps of
geologists is fairly unfamiliar
withRC
• Traditionally, RC drills have
been heavy and unsuitable for
remote areas
• Misconceptionsare still
prevalent regarding RC’s
compliance withNI43-101
• Some geos still think RC results can’t
beused in resource calculations
6. • RC is fast and cost-effective
• TheAustralian industry is
used to RC and trusts its
reliability
• Much of Australia lacks
water
• Access is often easy for big
truck-mounted RC drills
Australia - 90% RC vs 10% Core
7. RC is perfect also for Canada
• Bulky equipmentis no longer a reason to shun RC
• Northspan DESIGNED THE HORNET DRILL AND introduced light-weight RC in 2003
• Just like Australia, much of Canada has a water availability issue
• MANY AREAS ARE REMOTE AND Canada’s newest “frontier”, the Arctic, is basically a cold desert
• Even small diameter RC produces a sample 3.5 timesthe size of NQ core
• Superior repeatability in any situation with heterogenous mineralization
• Speed of RC drilling often means big savings on camp and logistics
10. Northspan Hornet RC Drill
• Modular design built for mobility. Components CAN BE MADE TO weigh less
than 1,250 lbs EACH
• Designed to be movedby light helicopter or fixed-wing (Twin Otter)
• Available in 100m (Hornet)and 200m (Super Hornet) hole depth
configurations
• Can be equipped withtracks, mounted on skids, etc.
• Ideal RC/RAB drill suitable for any stage of exploration/mining cycle
from basal till sampling and target testing to resource definitionand
grade control

13. Northspan Hornet XL Multi-Purpose Drill
• Multi-purposedrill originally designed to
tackle overburdensituations that cause
problems fortraditional drills
• Modular construction designed to be
mobilized by light helicopter or light fixed-
wingaircraft
• Versatile. Drill can employ several different
overburdenand drillingtechniques. Arsenal
includes RC, RAB, casing hammer and water
hammer systems.
• The HornetXL combines the capacities ofmuch
larger “road-based” drills into a smaller
package
15. Benefits of Northspan Drilling
• Faster. Save money. Drill more
holes.
• Produces reliable NI43-101
compliant results
• RC is themost reliable method in several
geological scenarios
• Needs little or no water
• Make water lines a thing of thepast!
• Light-weightand versatile
