Guidelines to submission of core and cuttings to the Earth Resources Core Library

March 2015

The Geological Survey of Victoria (GSV) encourages industry, academia and other interested parties to provide core and cuttings samples from drilling programs for storage at the Earth Resources Development (ERD) Core Library. Such material will be useful in future exploration and research.

All core/cuttings should be packaged in clearly labelled core trays with the name of the hole, the start and finish depth and tray number clearly visible on the front of the tray (i.e., the end the core interval starts). Core should also be clearly marked to show orientation.

In general, borehole intervals spanning important geological structures, mineralised zones and significant intersections as well as intervals hosting significant or unusual structures and mineral assemblages are sought.

Due to limited storage space it is generally not possible to accept all samples from an individual drilling program although individual bore holes would definitely be considered. Where good examples of particular deposit styles, structures etc. from a particular area are already held in our collection we may consider not accepting more samples.

Since the samples will generally represent only selected intervals/boreholes, a brief report on the significance of these samples should also be submitted for future reference. All core/cuttings should be packaged in clearly labelled core trays and orientation should be clearly marked.

Samples should be submitted prior to the relinquishment, or expiration, of the licence under which they were acquired.

Samples can be delivered to the ERD Core Library at 18 South Rd, Werribee by prior arrangement. Contact the Core Library Manager, Ken Sherry, on 0425 748 225 or 03 9027 4458 Monday, Thursday or Friday, or on 03 9742 8688 Tuesday and Wednesday (Core Library). Alternatively email ken.sherry@ecodev.vic.gov.au

The Core Library is usually open on Tuesdays and Wednesdays and has a forklift onsite to unload pallets. Core trays stored on pallets should be firmly strapped with lids on the top layer.

For individual exploration programs, information on the samples submitted should be provided in digital and hardcopy in order to provide future geoscientists with information/data which can be easily formatted.

Data Requirements

The following data will probably only need to be supplied once for a dataset, rather than for each borehole. If it differs between individual bores in the set, details will be required. Analytical results and methods would be beneficial to avoid the need for additional sampling.

Data Requirement Example
Exploration Company Compulsory owner company name
Purpose Compulsory eg minerals, extractive, general geological
Tenement/s Compulsory will help determine when confidentiality ends
Reports Compulsory complete details of reports referencing the hole/s
Location method Compulsory plus/minus meters accuracy for location
Location accuracy Compulsory method of obtaining location etc. GPS, topo map
Drilling contractor Preferred drilling company name
Method Compulsory eg diamond, air core, percussion etc

Bore – Metadata

Data Requirement Example
Co-ordinates-easting Compulsory Six figures
Co-ordinates-northing Compulsory Seven figures
Co-ordinates-zone Compulsory Either MGA54 or MGA55
Co-ordinates-datum Compulsory GDA94
Elevation accuracy Compulsory should be supplied if elevation supplied
Elevation datum Compulsory should be supplied if elevation supplied
Drilling start date Compulsory At least one date required
Drilling completion date Preferred  
Bore depth Compulsory metres
Bore confidential Compulsory Y/N
Local name Optional Free text name assigned by the company (ie prospect)
Map name Preferred  
Elevation Compulsory Elevation at ground level
Parish Optional If known
Type Compulsory eg diamond drill, sidewall
Depth from Compulsory metres
Depth to Compulsory metres
Recovery % Preferred Proportion of sample when originally recovered from the borehole
