Geopyörä seed investment with Chrysalix Venture Capital
Some milestones are business milestones. Others feel like the beginning of a new chapter. Today I’m incredibly proud to share that Geopyörä has closed its seed investment with Chrysalix Venture Capital. This is a huge moment for us. We started Geopyörä with a simple but stubborn belief: mining needs far better ore body knowledge. Not just more assays. Not just more models. Better data on how rocks actually behave when they are crushed and ground, because ore hardness drives t

Development and validation of artificial intelligence models to predict standard comminution parameters
We have a new peer reviewed paper in Minerals Engineering showing how Deep Neural Networks predict standard comminution parameters directly from Geopyörä breakage test data. The result is higher accuracy with smaller samples and faster turnaround. What this means for you: - Less sample mass, more samples across the orebody, better variability capture - Direct prediction of Axb/DWI and BWI from force, energy, t10, SG and related features - A clear path to scale geomet prog

Pre-print of new Geopyörä paper at the Minerals journal!
Our most recent paper validating the " Accuracy and Precision of the Geopyörä Breakage Test" has just been approved for pre-print! This study had two main objectives. First, we assessed the accuracy of the Geopyörä compared to the standard DWT test across measurements from seven different ore bodies. Secondly, we validated the precision of the Geopyörä device using the Round-Robin methodology with four distinct Geopyörä devices from different laboratories. If you're interes
