There are several classification systems for the economic evaluation of mineral deposits worldwide. The most commonly used schemes base on the International Reporting Template, [1] developed by the CRIRSCO – Committee for Mineral Reserves International Reporting Standards, like the Australian Joint Ore Reserves Committee – JORC Code 2012, [2] the Pan-European Reserves & Resources Reporting ...
The National Instrument 43-101 requires substantially more technical disclosure to the market than the equivalent JORC Code, because the JORC Code is primarily a code for reporting the status of a mineral resource, whereas NI 43-101 is a code of securities disclosure. This distinction is based on the derivation of the two codes: the JORC Code ...
The JORC [5] Code was first published in 1989, with the guidelines published in 1990. During the 1990s, it became clear that the evaluation of mineral deposits should be based on an internationally recognised code of reporting in order to improve the security of investments in this economic sector (e.g. Bre-X case).
Windows File Recovery is a command-line software utility from Microsoft to recover deleted files. [1] [2] It is freely available for Windows 10 version 2004 (May 2020 Update) and later from the Microsoft Store. [3] Windows File Recovery can recover files from a local hard disk drive (HDD), USB flash drive, or memory card such as an SD card.
Classification and management of natural resources such as minerals and petroleum are classified using differing schemes. [4] [5] In 1997, UNECE published the United Nations Framework Classification for Reserves and Resources of Solid Fuels and Mineral Commodities (UNFC-1997) as a unifying international system for classifying solid minerals and fuels.

The most common data recovery scenarios involve an operating system failure, malfunction of a storage device, logical failure of storage devices, accidental damage or deletion, etc. (typically, on a single-drive, single-partition, single-OS system), in which case the ultimate goal is simply to copy all important files from the damaged media to another new drive.
Mineral resource estimation is used to determine and define the ore tonnage and grade of a geological deposit, from the developed block model.There are different estimation methods used for different scenarios dependent upon the ore boundaries, geological deposit geometry, grade variability and the amount of time and money available.
Recuva (/ r ɪ ˈ k ʌ v ə /) [2] is an undeletion program for Windows, developed by Piriform Software. It is able to undelete files that have been marked as deleted ; the operating system marks the areas of the disk in which they were stored as free space. [ 3 ]
