Serica Energy's shares
gained after the oil and gas company narrowed its pre-tax losses in the first half as it lowered its costs.
The loss before tax came to $1.9m, down from last year's loss of $3.5m.
Sales revenue fell to $3.5m from $8.4m, but was offset by a reduction in cost of sales to $2.9m from $9.1m.
A fall in expenses to $2.5m from $3.5m last year, cut the operating loss to $2m from $4.2m.
Tony Craven Walker, Chairman and Interim Chief Executive Officer, said the company was entering a period of "significant activity".
"Our drilling campaign kicks off in October with the spudding of our first well offshore Morocco and will be followed by a further well offshore Morocco in the first half of 2014 and a well in the UK (Doyle)," he said.
"In Ireland efforts have commenced to identify partners to accelerate drilling on our Boyne and Muckish prospects. In Namibia, well planning activities have commenced in preparation for drilling in late 2014/15."
He added that while financial markets remain difficult for exploration companies, the group has been able to secure finance from major international oil firms.
The company has sufficient funds to meet its exploration and other commitments for 2013, but remains very tightly financed.
As a result, the group is reviewing alternatives to strengthen its resources for 2014 and beyond and place it on a stronger footing to maintain its growth targets.
Serica had unrestricted cash balances of $14.9m at the end of June.
Bango's shares fell after the mobile web payments and analytics company said it widened losses in first half.
Adjusted earnings before interest, tax, depreciation and amortisation (EBITDA) came in at a loss of £1.18m, compared to last year's loss of £0.98m.
Losses per share rose to 3.87p from 3.23p, while the loss before tax climbed to £1.83m from £1.32m in 2012.
The losses reflected a drop in turnover to £4.54m from £5.67 last year, including a fall in end-user activity.
Turnover was affected by the transition of the business from feature phone to smartphone and app store based activity as well as the inclusion of agency fees in end user activity.
Total operating costs excluding depreciation, amortisation and share based payment increased to £2.37m from £1.65m due to investments in the capability and connectivity of Bango datacentres, additional contingency and security measures, and a new operations team of 10 people.
Nevertheless, the group achieved a 78% rise in total gross profit to £1.2m, supported by a growing number of smartphone users.
End-user spend climbed 27% to £6.6m compared last year. The total margin surged to 26.21% from 11.8%.
"Bango has now successfully progressed smartphone opportunities so that there has been a solid return to growth in the first half of 2013 and a continuation of growth into the second half," said Chief Executive Officer Ray Anderson.
"Continued growth of BlackBerry World is being augmented by substantial growth from newer deployments such as Google Play, Microsoft Windows Phone Store, Facebook and Android users. The developing relationship with Microsoft and the very new relationship with Mozilla position Bango favourably for success in emerging markets, such as India, Brazil, Malaysia and Indonesia."
