Kimberley Big Hole & Mining Complex
South Africa
Kimberley Big Hole & Mining Complex is strongest on Population Capacity 5/10 — The attraction explicitly handles groups of 20 or more and has multiple buildings plus on-site accommodation and food-service facilities, so the fixed reference group is clearly plausible. Public evidence does not establish enough residential sanitation and storage headroom to claim substantially larger survival-community capacity.. Its clearest scored constraint is Defensibility 2/10 — The present Base is an open visitor and museum complex around a huge excavation, not an active fortified mine. The crater creates a major terrain obstacle for some positions, but it does not form a continuous defended boundary and the broad attraction would require extensive improvised perimeter work..

Bottom Line
For the fixed 20-person Base boundary, the most important endurance constraint is Resource Security 2/10 — Current accommodation, bar and coffee-shop operation prove a real short-term supplied position with food and drink inventory on site. Those resources are commercially replenished, and no authoritative current evidence establishes protected independent potable-water capacity, durable food production or survival-critical energy independent of Kimberley municipal and commercial systems. The evidence therefore fits the short-term-only anchor..
Biggest Trade-off
The central trade-off is the catalogue's strongest evidenced dimension, Population Capacity at 5/10, against its weakest evidenced dimension, Defensibility at 2/10.
Most Likely Failure
The evaluation leaves this material failure condition unresolved: Current accommodation and food/drink service prove a supplied short-term resource position, but no independent protected potable-water source, storage or treatment pathway is established. Resource Security 2 preserves that distinction for package adjudication.
Score rationale
Why it scores this way
Defensibility · 2/10
The present Base is an open visitor and museum complex around a huge excavation, not an active fortified mine. The crater creates a major terrain obstacle for some positions, but it does not form a continuous defended boundary and the broad attraction would require extensive improvised perimeter work.
Advantages
- Positive credit is limited to what supports the Defensibility score of 2/10; the component rationale is: The present Base is an open visitor and museum complex around a huge excavation, not an active fortified mine. The crater creates a major terrain obstacle for some positions, but it does not form a continuous defended boundary and the broad attraction would require extensive improvised perimeter work.
Limitations
- Do not infer additional Defensibility capability outside the fixed Base boundary or beyond the recorded evidence.
Isolation · 2/10
The Big Hole complex is embedded in Kimberley. Historic mine depth or industrial identity does not create geographic separation from the surrounding city, so nearby population pressure remains substantial.
Advantages
- Positive credit is limited to what supports the Isolation score of 2/10; the component rationale is: The Big Hole complex is embedded in Kimberley. Historic mine depth or industrial identity does not create geographic separation from the surrounding city, so nearby population pressure remains substantial.
Limitations
- Do not infer additional Isolation capability outside the fixed Base boundary or beyond the recorded evidence.
Sustainability · 4/10
Current accommodation, visitor buildings, food-service facilities, first-aid capability and restored Old Town structures make prolonged shelter for twenty plausible with adaptation. The site is designed for tourism rather than residential self-sufficiency, while the open pit and dependence on ordinary utilities impose substantial compromise.

Survival horizons
How survival changes over time
First 7 days: current defence/contact profile
First 7 Days
This horizon does not invent future upgrades or resupply. It carries the current evaluated conditions forward and keeps unknown future capability uncredited.
Positive factors
- The stronger current condition in this horizon is Exposure Control 3/10 — The crater shapes movement locally, but the surrounding urban setting and large attraction footprint leave multiple ordinary approaches to occupied buildings. The hole cannot be treated as a universal moat around the Base..
Risks
- The weaker current condition in this horizon is Defensibility 2/10 — The present Base is an open visitor and museum complex around a huge excavation, not an active fortified mine. The crater creates a major terrain obstacle for some positions, but it does not form a continuous defended boundary and the broad attraction would require extensive improvised perimeter work.; no better future state is assumed.
First 100 days: current habitat/capacity profile
First 100 Days
This horizon does not invent future upgrades or resupply. It carries the current evaluated conditions forward and keeps unknown future capability uncredited.
Positive factors
- The stronger current condition in this horizon is Population Capacity 5/10 — The attraction explicitly handles groups of 20 or more and has multiple buildings plus on-site accommodation and food-service facilities, so the fixed reference group is clearly plausible. Public evidence does not establish enough residential sanitation and storage headroom to claim substantially larger survival-community capacity..
Risks
- The weaker current condition in this horizon is Sustainability 4/10 — Current accommodation, visitor buildings, food-service facilities, first-aid capability and restored Old Town structures make prolonged shelter for twenty plausible with adaptation. The site is designed for tourism rather than residential self-sufficiency, while the open pit and dependence on ordinary utilities impose substantial compromise.; no better future state is assumed.
Long term: current resource/maintenance profile
Long Term
This horizon does not invent future upgrades or resupply. It carries the current evaluated conditions forward and keeps unknown future capability uncredited.
Positive factors
- The stronger current condition in this horizon is Maintenance Resilience 4/10 — Most useful shelter consists of ordinary preserved or restored buildings whose basic enclosure remains valuable without specialist mining machinery. Current accommodation, food service, water, sanitation and visitor systems still depend on municipal utilities and routine commercial maintenance, so functionality would degrade materially but not collapse as a single technical system..
Risks
- The weaker current condition in this horizon is Resource Security 2/10 — Current accommodation, bar and coffee-shop operation prove a real short-term supplied position with food and drink inventory on site. Those resources are commercially replenished, and no authoritative current evidence establishes protected independent potable-water capacity, durable food production or survival-critical energy independent of Kimberley municipal and commercial systems. The evidence therefore fits the short-term-only anchor.; no better future state is assumed.
Tactical assessment
Practical Reality
Reality Check
Scores apply only to the defined Base and exactly 20 capable adults. Unknown, excluded or external assets are not credited as hidden capability.
Best Use
Within the evaluated boundary, treat Population Capacity as the primary operational strength; do not promote that score into capabilities the evidence does not establish.
Key Risk
Resource Security is the key evidenced long-duration risk: Current accommodation, bar and coffee-shop operation prove a real short-term supplied position with food and drink inventory on site. Those resources are commercially replenished, and no authoritative current evidence establishes protected independent potable-water capacity, durable food production or survival-critical energy independent of Kimberley municipal and commercial systems. The evidence therefore fits the short-term-only anchor.
