To celebrate the 20-year Anniversary of Reconcilor, Rayleen Hargreaves our Reconcilor Product Owner chats to Craig Morley Anglo American's Head of Mining Geosciences and Reconciliation about the key roles they have played in the genesis, development and roll out of the reconciliation software Reconcilor. Prior to joining Anglo American, Craig was with Snowden for 18 years and it was during this time that Reconcilor was born. Here we are 20 years later and Reconcilor is working its magic on 31 mine sites around the world.
