History
The Kang-Kokong kimberlite field (cluster) was discovered in the 1970's through sampling and magnetic work undertaken by De Beers and Falcon Bridge.

At the time of acquisition by the Company, the licenses were known to host 34 kimberlite occurrences, 14 of which were diamondiferous yet uneconomic. The Company initially flew a Fugro 22,000 kilometer line mag. survey that identified 96 targets, of which 50 were considered to be a high priority.

Geology of Botswana
Rocks of the Karoo Supergroup (259 to - 100 Ma) overlie approximately 70% of Botswana's archaean and proterozoic rocks.

Botswana is host to over 240 kimberlites, most of which occur in clusters. The majority of clusters occur within the Archaean-age Kaapvaal-Zimbabwe craton.

Licenses
In February 2002, Azure signed a joint venture (J/V) agreement with Tinto Botswana Exploration (Pty) Ltd., a subsidiary of Rio Tinto Mining, London ("Rio Tinto").

Under the terms of the J/V agreement, Rio Tinto has earned a 65% participating interest by making a total of USD $3.5 Million in work expenditures which have now been completed.

Rio Tinto will earn an additional 10% interest by completing a pre-feasibility study, initiating a feasibility study and incurring a further USD $5.0 Million in expenditures by September 21, 2012. Tinto Botswana is the operator of the project. Azure is freely carried for 25% interest up to the mining stage.
