  5. Specify your search parameters and click Search, as shown in Figure 3. In this example we are searching for operating mines in Australia that have zinc in Proved Ore Reserves (PVR). Table 1 details the Joint Ore Reserves Committee (JORC) classifications. For further information on JORC visit

The Resources Search produces multiple results for each mineral deposit, as evident in Figure 4 above. Even though these records may appear to contain the same information, they are not duplicates. The search works by producing a record for every commodity which appears in the JORC classification specified in your search, within each mineralised zone of the deposit.

  1. To help illustrate this, click on page 3 in the Search Results from the above example (Figure A) and refer to the Mt Garnet and Mt Isa results listed in Figure B.
  2. Figure B Image

  3. While there are three entries for Mt Garnet, we can see by referring to the CommodID column that these records correspond to three different commodities. Click on the Info Icon icon next to any of these Mt Garnet records to view the details for this deposit.
  4. Figure C Image

  5. As evident in Figure C above, Mt Garnet contains reserves figures for three commodity types under the ‘Proved’ JORC classification. Since zinc (the commodity specified in our search) is amongst them, a record is produced for each, which is why Mt Garnet contains three records.
  6. You may have noticed in Figure B above that although Mt Garnet contains one record for each commodity with Proved reserves, Mt Isa contains two for each commodity. Click on the Info Icon icon next to Mt Isa in the search results to view its details. The results are shown in Figure D.
  7. Figure D Image

  8. Mt Isa contains three mineralised zones, unlike Mt Garnet which contains only one. These are: Black Star, Mount Isa (Lead-Zinc-Silver Underground) and Mount Isa Open Cut (lead-Zinc-Silver). Since both Black Star and Mount Isa Underground contain Proved zinc reserves the search will show a record for each commodity listed in them, which in this case means there will be six records under Mt Isa, which indeed there are. Since the third zone (Mount Isa Open Cut) does not contain Proved reserves data, it did not produce any records in our search.
