So many factors with cut off grade open pit & underground re depth

Determining whether a 0.1% cut-off grade is economical for mining antimony depends on several factors, including the mining method, processing costs, market prices, and the specific characteristics of the ore body.
Generally, a cut-off grade of 0.1% antimony is considered low, and its economic viability would depend on factors such as:

1. Mining Method: Open-pit mining is typically cheaper than underground mining. If the antimony deposit is near the surface, it might be more economical to mine¹.
2. Processing Costs: The cost of extracting and processing the ore can significantly impact the economic viability. Lower-grade ores require more processing, which can increase costs¹.
3. Market Prices: The current market price of antimony plays a crucial role. Higher prices can make lower-grade ores more economical to mine².
4. Ore Body Characteristics: The size and concentration of the ore body, as well as its proximity to existing infrastructure, can affect the overall cost and feasibility¹.

MQR maybe in luck as drilling intercepts are relatively shallow
