Current Retention Licences

Regions showing the extent of mineral Retention Licences currently lodged with Earth Resources Regulations.\nThe boundaries are derived from a combination of entering graticular boundaries (exact MGA co-ordinates) and digitizing along areas of land status (Earth Resources version of plm25) which are unable to be mined or explored. Refer to the Mineral Resources (Sustainable Development) Act (MRSDA) 1990 for more detail.

展示当前已向《地球资源条例》（Earth Resources Regulations）备案的矿物留存许可证（mineral Retention Licences）覆盖范围的区域。该数据集的边界由两种方式结合生成：一是录入精确MGA坐标系（MGA co-ordinates）下的经纬格网边界，二是沿无法开展采矿或勘探活动的土地权属区域（地球资源版plm25）进行数字化。如需了解更多详细信息，请参阅1990年《矿产资源（可持续发展）法》（Mineral Resources (Sustainable Development) Act 1990，缩写MRSDA）。
