Ore deposit is an economic term, while mineral deposit is a geologic term. Whether a given mineral deposit is also an ore deposit depends on many factors other than the level of concentration and the size of the deposit; all factors that affect the mining, processing, and transporting of the ore must be considered as well.

Mineral deposit - Mineral deposit - Formation of mineral deposits: Mineral deposits form because some medium serves as a concentrating and transporting agent for the ore minerals, and some process subsequently causes the transporting agent to precipitate, or deposit, the minerals. Examples of concentrating and transporting agents are groundwater, seawater, and magma; examples of
A modified version of these mineral deposit models for Australia's major mineral deposit types is available on the Australian Mines Atlas.

A mineral deposit is a natural concentration of minerals in the earth’s crust. The degree of concentration is called the "grade" of a mineral deposit. An "ore deposit" is a mineral deposit which has high enough grades of metal that makes it economic to mine.

Mineral deposits are one very small, but economically important, part of a much larger geosystem, the mineral (or mineralising) system. Although the search for mineral deposits has some similarities to the proverbial "needle in a haystack", the signatures of mineral systems typically extend well beyond the mineral deposit and, as such, represent a much larger target for exploration.
Mineral exploration plays a key role in ensuring the long-term viability of Canada’s mining industry. It leads to the discovery and development of mineral deposits that may become future mines, creates jobs—often in remote and northern communities—and attracts significant investment.
2019-11-04 Our objective is to develop a national-scale, geospatial database that is the authoritative source of the most important mines, mineral deposits, and mineral districts of the United States.

The discovery of very large sedimentary deposits of phosphate in the Southern States of the United States killed Canadian phosphate mining. The only chance of its revived lies in the possible, but not very probable, discovery of an unusually large and regular body of the mineral that could be mined more cheaply than the pocketty masses so far found.
Tungsten deposits are thought to form at depths comparatively higher than porphyry systems. Despite their depth of formation, there is evidence that meteoric fluids eventually percolate into these systems. The timing of meteoric fluid infiltration in these systems and the role that they may play in mineral precipitation remains unclear. This ...
