Hey there. Important we understand that Lundin Mining production is primarily focused on copper.
In fact, 2020 production thus far has been nearly 70% copper. And, the price of copper has increased substantially since September.
I've attached a chart for you, showing Lundin's stock price and the price of copper. We can see that over the last 5 years, besides a very brief period in 2019, Lundin has followed the price of copper pretty accurately.
So, to answer your question, if copper prices continue to rise, we will likely see Lundin rise as well, at a faster pace typically than the price of copper. However if copper were to fall, we'd like see Lundin fall even more than the change in price of copper.
This is because producers are often more volatile than the underlying commodity they rely on. For example, if gold falls 5%, we can expect a producer with high exposure to gold to fall more than this, and vise versa. Same could be said with oil.
