That's true. So will depend on how many sites a customer has and how many they choose to use Envirosuite.

However, I have a feeling that most customers would not have that many sites or at least not 9 to 10 sites to achieve revenues of $500k per customer as was stated earlier by another poster.

In the latest announcement, it was stated that the company had secured contracts to 3 adjacent mines. I assume this means that enviro suite is being used at 3 coal mining 'sites' with each site using 4 modules. So maybe around $100k per site or $300k for the 3 new customers. No details on margins ( as far as I can see) have been released by the company so IMO, they still need a lot of customers before they can achieve the benefits of economies of scale.

Still believe that's why the share price is where it is as the company still needs to prove that they can secure a large number of customers as quickly as possible and also to demonstrate that their existing customers will continue to use their products in subsequent years.

I personally believe they can and that's why I'm a shareholder.
