Social media video producer Brave Bison PLC (LON:BBSN) got a better look this week after its new male grooming show racked up 2mln subscribers since launching on Snapchat in December.

Slick, aimed at young men looking to keep up with the latest haircuts and facial hair trends, is part of the new ‘Snap Originals’ section of the app where users can stream five-minute episodes, like a snappier version of Netflix.

The shares scrubbed up well after the news, spiking 11% to 1.2p, giving some respite to the struggling social media specialist.

Last year the group’s troubles worsened and the share price more than halved as losses continued and April brought a new content policy at Facebook that blocked advertisements on the company’s four largest pages.

After a management spring clean, incoming new boss Kate Burns pushed for entry into the “less obvious” Snapchat market which is seemingly bearing fruit.

Gemfields Group PLC (LON:GEM) joined the market on Valentine’s Day, trading at 11p after a two-and-a-half-year hiatus.

The emerald, ruby and amethyst miner, owner of jewel eggs producer Fabergé, was taken private under its old guise by Pallinghurst in July 2017.

Looking at the wider market, the AIM All-Share was broadly flat at 965, same as the FTSE 100 steady at 7,454.

Another top loser was Mosman Oil and Gas, which collapsed 42% to 0.15p after executive chairman John Barr and technical director Andy Carroll bought 41mln shares at a 40% discount to Thursday’s closing price.

Management claims the cheaper shares were in lieu of A$120,000 worth of director and consultancy fees for the year to 30 June.

Fellow oiler Ascent Resources PLC (LON:AST) descended 40% to 0.06p after its chairman and finance director departed to make way for industry veteran James Parsons.

The share price crash reflected an £800,000 fundraise at a 44% discount on Thursday’s closing price.

Re-refiner of oil Hydrodec Group PLC (LON:HYR) diluted 36% to 6p as higher costs of feedstock in the first half of 2019 hit full-year revenues and earnings.

Adhesive specialist Scapa Group PLC (LON:SCPA) slumped 27% to 193p after forecasting “significantly” lower earnings due to a sharp downturn in revenues from its industrial division.

Similarly, retailer United Carpets Group PLC (LON:UCG) tanked 24% to 4p after warning profits will be half of the expected £500,000 due to a “very competitive” market.

Elsewhere, technology-focused investor MXC Capital Ltd (LON:MXCP) plunged 15% to 59p as it wants to delist from AIM.

The company reckons it could save around £300,000 a year going private as it did not raise any fresh capital in the last four years and “has no intention of doing so for the foreseeable future”.

Financial advisor Frenkel Topping Group PLC (LON:FEN) slipped 9% to 41p on a failed takeover from investment manager Harwood Capital.

We will see how it plays out for podcast outfit Audioboom Group PLC (LON:BOOM), which advanced 19% to 266p after confirming it is up for sale, though it has not yet received any bid approaches.

But on top of the risers was Premier Oil PLC (LON:PMO), rocketing 56% to 0.1p, after the majority of its creditors backed a financial restructuring necessary to buy BP’s assets in the North Sea for US$625mln.

Freight services manager Xpediator PLC (LON:XPD) flew 26% higher to 35p after posting 20% turnover in 2019 boosted by acquisitions and organic growth.

Meanwhile, polymers producer Itaconix PLC (LON:ITX) polished up a 19% gain to 1.6p as it signed agreements with supplier New Wave Global Services for a new dishwasher detergent formulation.

Elsewhere, human resources firm ClearStar Inc (LON:CLSU) jumped 14% after securing a job with an unnamed company bringing in at least US$400,000 a year.

Pharma company Diurnal Group PLC (LON:DNL) shot up 13% to 28p after interim revenues for Alkindi, a treatment for hormonal diseases, soared 516% on 2018.
