CC41_IB1_B1 DRILL PREP

Has this prep ran over the due date?

ACCESS TRACK SURFACE CONDITIONS - Surface Condition <br>Is bench safely accessible for water/service trucks (min 10m width)

ACCESS TRACK SURFACE CONDITIONS - Graded and be of a camber/cross fall in accordance to site standard allowing light and medium vehicles to access the area safely

ACCESS TRACK INTERACTIONS - Has the access track onto the bench been constructed to allow limited interaction with other operations? Use back roads where possible.

ACCESS CONTROLS - Have physical hard barriers been established for the bench and access only via designated entrance points?

ROADS/RAMPS - Where ramps exist, are they constructed no greater than 10% grade? Use device to confirm.

INTERSECTIONS - Are all intersections constructed as 'T' intersections providing 90 degree angle of approach? Intersection must be in compliance with DNM-CHL-0013 (checklist for intersection design and construction available on tempo).

DROP OFFS/OPEN EDGES - Have all drop-offs/open edges greater than 0.5 m been adequately bunded at the correct height?

FACE/CREST BUNDING - Has bunding at the face been pushed to the safest limit (half the wheel height of the largest vehicle accessing the area) as close to the crest as possible and at correct height for equipment entering areas?)

DRAINAGE - Is adequate drainage on the bench, have drainage slots been achieved along the face?

GEOTECHNICAL - Are all geotechnical hazards controlled by adequate bunding and exclusion zones are in place and surveyed in by the AH builders if required?

BENCH SURFACE CONDITIONS - Has bench been prepared to an acceptable standard - 7% Grade throughout. (graded off excessive loose material, grader rills, rocks cleared and low spots identified)

PUMPS & PIPELINES - Have all pumps and pipelines been removed from pattern or relocated to an agreed area where potential damage to holes can be minimised? Include pipeline flow meter risk for flyrock. Ensure notifications are raised where required.

CABLES & TOWERS - Have all Cables been removed from pattern or relocated to an agreed area where potential damage to holes can be minimised? Ensure notifications are raised where required.

TECHNOLOGY & AH - Have all AOZ requirements been met? Exception zone created, signs in place? All coms trailers removed from pattern?

INFRASTRUCTURE - Have all Infrastructure been removed from pattern or relocated to an agreed area where potential damage to holes can be minimised? Ensure notifications are raised where required.

DESIGN - Has design been completed and have limit pegs, tape and minestar limits been placed to provide clear instruction to execute works.

ENVIRONMENT - Has a permit to disturb been executed and do all operators understand the required controls. Keep permit to disturb in cab of disturbance vehicles on required patterns

LIMITS - Have bench limits been met, has survey checked area to ensure design limits have been achieved for next process

DUST MANAGEMENT - Has floor been graded off or sheeted where high dust generation exists?

SPON COM - Is there a spon com risk in this pattern?

CRIB HUT - Is there suitable location for crib hut with turn around room? Does further notifications to mine services need to occur or mine planning design need to occur.

FLOAT - Is there sufficient room to load and unload equipment with the float? Does further notifications to mine services need to occur or mine planning design need to occur.

Is there any non-compliance to the drill preparation standard as outlined in this inspection
