This site is dedicated to what has passed in the mining industry, but some of us who have worked in the mining industry do understand how difficult it is to get your first footing in the industry
My advice would be to use the various international Mining Institutes, LinkedIn or other social networks to find former students of the Zimbabwe School of Mines outside of ZW (directly in mining companies or in supporting organisations such as consulting engineers, mining software houses etc) and make direct approaches with your CV.
Good luck, I was in the same situation in 1982 ...... with a bit of effort/luck I ended up with a degree in mining engineering and a nineteen year career in the coal industry. These days I use the skills I learnt in the heavy end of the civil engineering industry!
