Serabi Gold PLC (LON:SRB) shares climbed 6.3% to 41p in late-afternoon trading as the miner announced an increase in strike extensions at its Coringa gold project in Brazil.
The company said exploration drilling at the Serra, Meio and Galena ore zones had revealed a series of high grade gold intersections that “significantly” extended previously modelled zones.
Another exploration firm, Kodal Minerals PLC (LON:KOD), jumped 2% to 0.19p as it acquired more ground close to its Bougouni lithium prospect in Mali.
Kodal will pay current owner Bampara £185,000 in cash and £195,000 in shares over three stages for an 80% stake that will give it exclusive rights to explore the new concessions.
Completing the mining trifecta was Erris Resources PLC (LON:ERIS), which saw its shares rise 7% to 7.5p after the latest drill results from the Abbeytown zinc-lead-silver-copper project in Ireland extended mineralisation south to join with the surface drilling completed last year.

1.00pm: Aukett Swanke plunges as full year loss widens
Shares in Aukett Swanke Group PLC (LON:AUK) plunged 24% to 0.99p in lunchtime trading after the architecture and interior design firm posted a wider loss for the year.
In the 12 months ended September 2018, the company reported a pretax loss of £2.5mln, wider than the £325,000 loss the year before.

Meanwhile, oil group Ophir Energy Plc (LON:OPHR) jumped 6.5% to 53.9p after it agreed to a £390mln takeover offer from Indonesian rival Medco Energi.
Ophir produces around 25,000 barrels of oil equivalent in the South-East Asia region, meaning Medco’s production will top 100,000 barrels per day after the takeover is completed.
The 55p per share offer was an upgrade on a previous offer of 48.5p earlier this month which was rejected by shareholders.
Elsewhere, shares in Katoro Gold PLC (LON:KAT) leapt 6.1% to 0.69p after a review and analysis of all historic work undertaken on the Haneti Nickel Project (HNP) in Tanzania led it to identify several high priority exploration targets.

Revenue for the year was expected to be approximately £80mln. The group currently has in excess of £85mln of revenue contracted for 2019.
In December, the company said an accounting review had resulted in a reduction in profitability of around £13mln, landing it at the £7.35mln loss forecast.
Meanwhile, marketing firm Taptica PLC (LON:TAP) surged 17.6% to 197p after it said it was planning a merger with fellow online video marketing firm RhythmOne PLC (LON:RTHM).
