Submit drill core samples
The Geological Survey of Victoria (GSV) encourages industry, academia and government to gift drill core and cuttings from drilling programs within Victoria to our Drill Core Library.
These drill holes will be made publicly available for future exploration efforts and applied geoscience research.
We encourage submissions of representative drill holes spanning important geological units, structures, mineralised zones and significant intersections. Our limited storage space means it is sometimes not possible to accept all samples from an individual drilling program although individual drill holes will be considered.
Where good examples of particular geological units, deposit styles, structures etc. from a particular area are already held in our collection we may consider not accepting additional drill holes.
How to package cuttings
All drill core/cuttings should be packaged in clearly labelled core trays. The following information needs to be clearly visible on the front of the tray:
- the name of the hole
- the start and finish depth
- tray number
- orientation markings, metre marks, sample intervals, lost intervals etc. should also be clearly marked.
How to deliver cuttings
Samples can be delivered to the Drill Core Library at 18 South Rd, Werribee by prior arrangement. The general expectation is that the owner of the drill core/cuttings will arrange delivery to us.
- Core trays stored on quality pallets should be firmly strapped with lids on the top layer.
- Individual pallets should not exceed one tonne in total weight.
- Forklifts and qualified operators are onsite to unload pallets.

Data Requirements
Digital and hardcopy details of the drill holes submitted should be provided to us to provide future geoscientists with the required data and knowledge.
The following data will probably only need to be supplied once for a dataset, rather than for each drill hole. If it differs between individual drill holes in the submission, details will be required. Analytical results (including associated metadata) would be beneficial to avoid the need for additional sampling. It is advantageous if the data already exists in a prescribed template (e.g. Mineral Reporting Template), however minimum guidelines are provided below.
| Data | Requirement | Example |
|---|---|---|
| Exploration Company | Compulsory | owner company name |
| Purpose | Compulsory | minerals, extractive, general geological, etc. |
| 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 | diamond, air core, percussion, etc. |
Drill hole – metadata

| 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 | e.g. diamond drill, sidewall |
| Depth from | Compulsory | metres |
| Depth to | Compulsory | metres |
| Recovery % | Preferred | proportion of sample when originally recovered from the borehole |
