Growth Strategy – ‘2 part’
1: Organic growth:
• Optimize/expand existing Holpan-Klipdam & Wouterspan operations
• ~20% leverage ability in short term with existing plant & equipment (ie. 2000 to 2400 carats per month)
• Evaluate/develop other properties already held in South Africa
• Develop DRC enterprise ~30km of 60km-long concession
![Page 18: KALAHARI DIAMOND RESOURCES PLC - Allan Hochreiter · 4 • John Bristow, PhD – geologist, ex De Beers, 25 years in alluvial diamond mining and kimberlite development. • Hennie](https://reader031.vdocuments.site/reader031/viewer/2022013007/5bfab39e09d3f24d478c4792/html5/thumbnails/18.jpg)
18
Growth Strategy – ‘2 part’
2: Acquisitive growth:
• Pursuing two established diamond operations with significant resources (+90M tonnes) in RSA
• Other private & listed diamond companies in RSA (via cash or ‘paper’)
• Double production (2000 to 4000 carats per month) in medium term (12 months)
• ‘Earmarked’ several ‘established’ ventures in other southern African countries
