cash burn rate = 7.7 years of working capital, page-6

"For the financial year ending 2012, Cokal's net cash outflow from operating activities was A$3.85m. The company as at 30 Jun 2012 had A$29.63m in cash or cash equivalents. "

yes, but Passport raised alot of capital by issuing a lot of shares

CKA's cash burn was $2m to $3m each quarter or around $10m for the year, including around $6m on administration

CKA forecast spend for the Sept 2012 quarter is $10m, including, $5m for BBM payment

CKA's cash balance will be around $20m at the moment

my old research states CKA may have future performance payments of $3m for BBP and $1.35m for AAK/AAM

so available cash is about $15m

if CKA gain good ground in Mozambique, $15m will probably last them another 3 to 4 months
