ANDOVER COMPLETES 2007 WORK/ DRILL PROGRAM AT SUN PROPERTY; REPORTS FIRST ROUND RESULTS FROM 2007 DRILLING
Andover Ventures Inc. has completed the 2007 exploration program at the company's flagship property, Sun, a volcanogenic massive sulfide (VMS) deposit located in the Ambler mining district in Brooks Range in northwestern Alaska. The company has now completed the camp winterization and has shipped the last of the core samples for assay. Two drill rigs have been retained on site to enable the company to commence its 2008 drill program in April of 2008.
Highlights of the 2007 work program included the installation of a new 20-man camp, a 1,500-foot airstrip, geochemical sampling along the strike of the mineralization at Sun and diamond drilling. The drilling commenced in late July, 2007, using two Boart-Longyear LF 70s to drill a total of 4,496 metres (14,750 feet) of NQ2 core in 20 holes.
Nineteen of the 20 holes encountered mineralized zones ranging from an estimated 1.20 to 24.0 metres (3.9 to 78 feet) thick, pending geochemical analyses, according to the geologic logs of the core. One hole crossed a fault where the mineralization apparently had been faulted out. Seven of the holes encountered two mineralized horizons and two more encountered three mineralized zones. The 30 total horizons encountered averaged over six metres (20 feet) in thickness of massive and semi-massive mineralization according to the geologic logs. All of the 2007 drilling at Sun was designed to be within 30 degrees of being perpendicular to bedding. Hence, these thicknesses should all be reasonably close to true thickness.
Complete results from 10 of the holes in the first phase of drilling are now in hand. Highlights include Sun 07-10, with an upper 10.94-metre (35.8-foot) intercept of 2.34 per cent copper, 0.77 per cent lead, 5.98 per cent zinc, 68.1 grams per tonne (g/t) silver and 0.266 g/t gold, and a lower 5.08-metre (16.7-foot) intercept of 4.34 per cent copper, 0.58 per cent lead, 2.76 per cent zinc, 99.1 g/t silver and 0.199 g/t gold.
Copper, lead, zinc, silver and gold analyses for the mineralized intercepts received from the lab to date are included in the drill results table.

The core samples were sawed and half the core was sent to Alaska Assay Labs in Fairbanks, Alaska, for a 30-element ICP-AA (induced coupled plasma-atomic absorption) analysis with gold and silver fire assayed with an AA finish. Base metal overlimits were wet assayed. Check assays are being done at ALS Chemex labs in Vancouver, B.C. All samples have been submitted to the laboratory and partial results from most of the holes have been received from the lab. Andover is holding release of the partial analyses, pending receipt of overlimit analyses for copper, lead and zinc. Full results will be released as these results are received over the next month.
Dr. David Hedderly-Smith, director, states: "The experience that Bill Ellis brings as project manager on the Sun property enabled us to successfully complete the 2007 drill program. As all assay results from the holes drilled are received from the labs, coupled with the data from the 49 holes drilled by Anaconda, Cominco and Noranda in the late 1970s, we hope to calculate a new NI 43-101-compliant resource calculation for the main Sun deposit. This drill data will also help us to plan our next drill program, expected to start in April, 2008."
Bill Ellis, manager for the Sun project, states: "Drilling at the main Sun deposit in 2007, was spaced along fences approximately 150 metres apart, with holes spaced approximately 50 metres down the dip of the mineral zones. The 2007 drill program tested approximately 1,400 metres along strike and approximately 250 metres in width. The 2007 program includes a 300-metre extension of the main Sun deposit to the north towards the Picnic Creek area."
Mr. Ellis also states: "After being part of the Sun deposit discovery team in the mid-1970s, it is very exciting to be managing this project. I am eager to get back to it in the spring of 2008!"

The company has granted incentive stock options to certain employees in the amount of 250,000 shares exercisable at 67 cents a share, subject to TSX Venture Exchange approval. |
