The junior oil and gas company reported a comprehensive loss of US$936,000, with administrative costs coming in at US$921,000 for the three month period.
In August, the company raised £500,000 via a stock placing at 0.1p a share.
At the time COPL noted that the new funds will help bridge the financial gap until the company can conclude its project financing plans.
Earlier, in May, it said it had conditionally agreed a package worth up US$50mln that would help it exploit the oil potential OPL 226 offshore Nigeria.
COPL and its local partner wants to bring three to four wells into production by the end of next year at rates of 6-10,000 barrels of crude per day.
