LONDON -- The FTSE 100 (INDEX: ^FTSE) fell a fraction, down 15 points to 5,647, after the big miners slipped a little. Fears of uncertainties from the forthcoming interim reporting season appear to be behind the wobble, though it may really be only noise following a couple of good weeks.

But even if the index of top shares is down, individual companies are moving in their own ways. Here are three from the FTSE indexes that have had a good day so far.

EMED Mining (LSE: EMED.L)
EMED Mining enjoyed an early 10% to 12.3 pence after the copper and gold miner announced a deal to acquire land for depositing waste, or "tailings," at the Rio Tinto Copper Mine.

The deal should satisfy all the company's needs for its current plans, and it helped the shares with an ongoing recovery that has taken them from a recent low of 7.75 pence to today's price.

Victoria Oil & Gas (LSE: VOG.L)
Victoria Oil & Gas gained some respite this morning as its shares popped 3.6% to 2.9 pence after a positive update from the firm's Logbaba operation in Cameroon. Gas and condensate production has commenced, with a start-up production of 700,000 standard cubic feet per day and is on schedule for a year-end production rate of 8 mmscf/d.

Victoria's shares have slid from a 4.8 pence peak in March, but with this new production -- the first in Cameroon to supply the industrial market -- we might well be looking at a corner turned.

GB Group (LSE: GBG.L)
GB Group shares perked up 3.3% to 78 pence on a strong first-quarter update. Ahead of its annual general meeting, the identity management specialist (electronic ID technology and such) said that its first quarter demonstrated "strong year on year growth, and (GB Group) continues to perform well."

The AIM-listed firm has been a classic growth story over the past few years, with the price rising from 16.5 pence in 2009. It's an area that should see increasing demand, and GB Group might be well-positioned to benefit from it.
