The firm will now hold a general meeting on 15 October where it will need to gain the support of 75% of shareholder votes to successfully delist from the junior market.

Meanwhile, cruise operator Carnival PLC (LON:CCL) sank 6.7% to 3,406p after it became the fourth FTSE 100 firm to issue a profit warning on Thursday.

1.30pm: China Nonferrous Gold hits jackpot as it turns a profit

Investors in junior miner China Nonferrous Gold Limited (LON:CNG) hit the jackpot in early afternoon after news that the firm had turned a profit in its first half sent the shares surging 25.7% to 20.8p.

The Tajikistan-focused gold player reported an operating profit for the six months ended 30 June of US$278,000, swinging from a US$3.36mln loss in the prior year, on the back of sales revenues of US$20.8mln.

The company sold 15,557 ounces of gold ingots in the period from its Pakrut Gold mine in the Central Asian Republic, which it had extracted from 300,300 tons of ore.

Elsewhere, fellow mining firm Vast Resources PLC (LON:VAST) shot up 36.2% to 0.16p after it formed two joint ventures with community interests and the Zimbabwe Consolidated Diamond Company for the Chiadzwa Community Diamond Concession.

The company also said it had resolved historic claims on the site by mutual consent, with the deals allowing the company to progress towards mining the area.

In the fallers, blue-chip educational publisher Pearson PLC (LON:PSON) slumped 15.9% to 724p after it joined multiple FTSE 100 firms issuing profit warnings on Thursday morning.

11.55am: Xaar red all over as it swings to loss, CEO exits

Printer ink maker Xaar PLC (LON:XAR) was red all over in late-morning after a swing to loss in its first half and the exit of its chief executive sent the shares plunging 39.1% to 42p.

For the six months ended 30 June, the company reported an adjusted pre-tax loss of £15mln, tumbling from a £3.2mln profit in the prior year, while revenues dropped to £22.5mln from £35.3mln.

Xaar was forced to get its red pen out for the numbers after a decision to cease all activities in its Thin Film business resulted in a £39mln impairment charge.

Meanwhile, the group also said its CEO, Doug Edwards, would be exiting the firm on 31 December after five years to explore opportunities in the USA, with the head of its printhead business, John Mills, to take over the role in 2020.

Another notable faller was FTSE 100 tobacco firm Imperial Brands PLC (LON:IMP), which tumbled 10.5% to 1,848p as investor choked on a profit warning issued in the wake of the US vaping scare.

In a pre-close trading update, the Lambert & Butler and Gauloises maker, said full-year earnings are likely to be flat, having previously guided to around 4% growth.

This is because net revenue is now expected to grow around 2%, having most recently pencilled in the upper-end of the 1-4% range.

The warning stemmed from the group’s push for market share gains in Australia and a deteriorating market for vaping in the US, which is dampening down demand for all e-cigarettes, including Imperial’s myblu.

In the risers, brake disk maker Surface Transforms PLC (LON:SCE) saw its shares motor up 6.4% to 25p after it was selected as a tier one supplier of carbon-ceramic discs to a major automotive company.

The company said it had received an order following its selection with sales revenue of £400,000 and expected to deliver the products before the end of 2019.

On the main market, breakdown and roadside repair firm the AA PLC (LON:AA.) rose 1.6% to 65.7p as it announced a partnership with ride-hailing firm Uber Technologies Inc (NYSE:UBER) to provide MOTs, repairs and maintenance services for its drivers.

The three-year deal, a first for the AA, will cover Uber’s 65,000 drivers which operate across 40 cities in the UK.

While the contract did not carry a monetary figure, the company said the partnership would provide a “significant opportunity” to grow new revenue streams without incurring substantial capital expenditure.

In the fallers, online estate agent OnTheMarket PLC (LON:OTMP) crumbled 16% to 81.5p after the firm cut its revenue and profit guidance for 2020 and 2021, citing headwinds in the market and “lower than usual” transaction volumes.

The group said the “challenging backdrop” meant it was becoming more difficult to convert estate agents into full-paying contracts for listings on its site and fewer were signing up than had originally been predicted.
