MINEDEX DERIVED

What is this layer?

MINEDEX DERIVED is an extraction of all point data of the MINEDEX database excluding those classified as targets and infrastructure.

Description

The MINEDEX DERIVED layer is an extraction of data housed in the MINEDEX database. MINEDEX provides a coordinated, project-based enquiry system for textual information on mine and deposit locations (coordinates etc.), as well as mineral resources, mine production, deposits, prospects and occurrences. Data is collated from ASX reports, statutory exploration reports, mining proposals and production returns.

The table below compiles the definitions for each type of site in MINEDEX DERIVED:

Site type

Definition

Mine

A deposit which is being mined, was previously mined, or is proposed to be mined.

Deposit

A mineral occurrence with probable economic value and for which there is an established resource.

Prospect

Any mineral occurrence where economic grades have been intersected over a significant width and strike length but for which there is not yet a resource, or any working or exploration activity that has found subeconomic mineral occurrences and from which there is no recorded production.

Occurrence

An occurrence (excluding those defined as mines, deposits or prospects) can be defined if an economic mineral has been identified in outcrop, or if assay results exceed an agreed concentration and size.

Unclassified

Mineralization site for which the TARGET_COMMODITY_GROUP does not reflect the specified commodity, and hence the SITE_TYPE_DESCRIPTION is not applicable.

Query

MINEDEX is filtered to retain mines, deposits, prospects and occurrences sites only using this SQL query
