EGBC National Exam — Mining and Mineral Processing Engineering, 09-MMP-A6 Mining and the Environment, undated sitting (the exam's own page header reads "National Examinations, May 2019"). 3 hours duration, open book (any non-communicating calculator permitted). Unlike most sittings of this subject, this paper's own Note 3 states "Complete all SIX questions" – there is no five-of-six choice, so all 120 marks are compulsory. Most questions require an essay-format or point-form answer; clarity and organization are explicitly assessed.
