Wow, for someone who has posted around 1600+ posts, this seems to be a pretty surreal question. Surely you know that apart from revenues, it costs something to get that copper out of the ground? That 'something' is usually termed as the C1 cost (there is a C3 cost as well as an AISC cost)
Typically, Oxide ore C1 costs are around USD1.91/lb and C3 costs of USD2.82/lb.
AISC costs are pretty much dependant on the sustaining CAPEX which is then divided by the total tonnage processed over the LOM (Life of Mine)
And no, I dont own shares in this company, I do own shares in Cyprium, though I wish I owned shares in Havilah as well.
Between Cyprium and Havilah - they are giants and have at least 3 million tons of Copper metal - not ore, but metal between them.
Thus, you can see that 28 mills of stuff at a mere 0.3% is not much - no seriously, it isn't. I'm not trying to bag your company, it is merely a matter of fact when you compare it to other giants in the copper industry. Obviously no one can compare it to the BHP's and Rio Tintos of the world, but we all have to start somewhere.
Apologies if I seem to come out of nowhere and swat ya - not intended, just came acrross this thread at random (home page browsing) and thought I would address this.
No doubt, you have invested in this company and would like to invest in other companies with different commodities, and I know what I would personally be doing.
This is a suggestion to you - try reading up on some basics on the various stages in the life cycle of a mining company. I've included some material that I personally consider quite decent and well researched.

Firstly we have the JORC code 2012:https://www.jorc.org/docs/JORC_code_2012.pdf
Read chapter "Reporting of Mineral Resources" para 20 onwards - it contains a brilliant explanation of why mineral resources upgrades are essential for Pre-Feasibility Studies. The following diagram is paramount to understanding the inter-relationships between resource and reserves


The following links to an article that discusses the 43-101 standard (followed in Canada/USA etc). The information is good though and applies in similar manner to the JORC standard:
