VANCOUVER, British Columbia--(BUSINESS WIRE)--Nov 10, 2026--

Neil Woodyer, Chair and CEO of Aris Mining, commented “Mining in the Segovia district spans more than 150 years, yet exploration continues to add gold to the reserve base. The 28% increase in reserves demonstrates that our exploration and resource conversion programs are doing more than simply replacing ounces produced. The increase in both contained ounces and grades reinforces the strength of this exceptional high-grade operation and supports our objective of continuing to extend Segovia’s mine life.

Segovia’s cash generation also provides an important foundation for our broader growth strategy. At the same time, we are advancing significant milestones across our portfolio, including the Toroparu prefeasibility study targeted for release later this month and marking the first time Aris Mining declares a mineral reserve estimate for Toroparu, and an updated NI 43-101 technical report for Marmato expected in the first quarter of 2027, following first gold from the new CIP plant. Together, these initiatives reflect our focus on sustaining the performance of our producing mines while advancing our growth projects.”

RAWALPINDI, Pakistan (AP) — Pakistan's debutants continued to inspire to leave Sri Lanka trailing by 320 runs with seven first-innings wickets in hand after two days of the first cricket test on Tuesday.

Fast bowler Saqib Khan, one of the four newcomers, brought the greenish pitch to life with 2-54 as Sri Lanka reached 114-3 before bad light brought an early closure for the second successive day. Nearly 26 overs were not bowled.

Only 67.2 overs were possible on Day 1 when Pakistan reached 281-5 with play continuing in floodlights for almost 45 minutes on both days at Rawalpindi Cricket Stadium.

Pakistan declared at 434-9 midway into the second session on Tuesday after five half-centuries — three to debutants — and a 48. Saud Shakeel missed out on his first century in over two years on 93.

At stumps, Kamindu Mendis survived a close lbw review and a leading edge fell just short of the fielder to be unbeaten on 40 and former test captain Dhananjaya de Silva had 22.

“There are about 140 chances that have missed the edge and beaten the bat from both sides, so probably says enough that there’s a chance of a result,” Sri Lanka fielding and spin coach Jordan Gregory said.

“So far Kamindu and DDS have put on a good partnership and we would like to see that partnership progress.”

Pakistan’s most experienced seamer Mohammad Abbas and Saqib hit the right lengths with the new ball and both struck in their second overs to have Sri Lanka reeling at 12-2.

Abbas extracted movement from his off stump line and found the outside edge of Pasindu Sooriyabandara, who was promoted to open the innings in his third test and out for a duck.

Saqib struck off his ninth delivery in test cricket when he squared up the experienced Dinesh Chandimal from a perfect length ball that angled across the right hander and edged the shoulder of the bat to the slips cordon.

Sri Lanka slumped further in the shortened final session when Lahiru Udara, who struck seven fours in his aggressive 42, played a loose drive to Saqib and edged to wicketkeeper Ghazi Ghori only two balls after a reprieve from Mohammad Taha, who grassed a one-handed catch at gully.

Mendis and de Silva survived under floodlights and added 49 runs for their unfinished fourth-wicket stand.

Shakeel’s steely 193-ball knock in just over 5 1/2 hours grew Pakistan's total in partnerships of 96 with Ghazi Ghori (48) and 44 with Arafat Minhas (52).

Minhas smashed nine fours and a pulled six off Lahiru Kumara before holing out to long-on when Pakistan was looking for quick runs in the second session.

Shakeel, on 91 at lunch, was out in the first over afterward for 93. Shakeel gloved a leg-side short ball and was caught behind to give Asitha Fernando (3-107) his 100th test wicket.

“You get too disappointed when you don’t complete a milestone (century),” Shakeel said. “The ball came too quick and probably that’s why I got out.

“Spin might come into play if there’s wear and tear on the wicket, but I don’t think reverse swing will come into play because of the lush green outfield.”

The Sri Lanka fast bowlers struggled to hit the right lengths on a consistent basis and the fielding was scrappy. Fernando dropped a skier off Minhas at mid-on before the left-hander completed his maiden test fifty off 70 balls.

Razaullah knocked a six and a four before captain Babar Azam declared when Razaullah was caught at long-off and gave Kumara his only wicket of the innings.

In a dominant first session, Pakistan added 109 to its overnight 281-5 and lost only the wicket of Ghori after Sri Lanka couldn’t penetrate through the middle order even with the second new ball.

Ghori couldn’t get his maiden test half-century and fell when he dabbed left-arm seamer Dilshan Madushanka (3-108) to Sooriyabandara at gully.

Shakeel, who scored his last test hundred against England here in 2024, rotated the strike and Minhas' positive intent ensured Pakistan score at more than four runs an over.
