Lottery management and payments specialist St James House PLC (LON:SJH) tanked 67% to 17.5p by mid-afternoon as its lucky numbers failed to come up and resulted in a profit warning.

The AIM-listed group, which changed its name from Boxhill Technologies earlier this year, said delays in issuing pre-paid cards for its new payment account service, particularly to a major client, meant that the target date for its full issue had been pushed back to January, and as a result it did not expect an improvement in its financial performance during the second half of its current year.

To make matters worse, the group also said its working capital position remained “constrained” as growth in its lottery management business failed to offset the losses from its payment division Caused by the card issue delays.

In the mid-caps, FTSE 250 housebuilder Crest Nicholson Holdings PLC (LON:CRST) subsided 6% to 383.4p as it warned investors profits will follow a downward trend over the next year, only to pick up in 2021.

This year’s accounts will factor in an extra £17mln expense to replace combustible materials as the government tightened regulations after the Grenfell Tower fire, the group said.

Meanwhile, junior miner Thor Mining PLC (LON:THR) sparked a 17% rise to 0.3p after announcing that it had recently begun talks with potential investors about a second of its projects while also expecting an initial resource estimate from the Bonya prospect in Australia before the end of the year.

In its latest quarterly review, Thor’s executive chairman Mick Billing said management has started “cutting non-essential project and corporate expenditure in order to conserve cash resources” while it continued to carry out talks with investors about its core Molyhil project and now also with US investors about the Pilot Mountain project in Nevada.

Aircraft and helicopter training specialist Pennant International Group PLC (LON:PEN) soared 13.3% to 85.5p in early afternoon as the firm delivered a double dose of good news.

Last month the bank suspended its share buyback as it warned of likely £1.2bn-£1.8bn PPI charges due to a spike in complaints in the final weeks leading up to the 29 August deadline, taking its total bill to around £26bn.

Underlying profits were also lower, down 12% to £1.82bn as net income fell 6% to £4.2bn due to a 2% dip in interest income and 12% fall in other income.
