Sept 8 (Reuters) - Anglo American AAL.L is nearing a deal to acquire Canadian miner Teck Resources TECKb.TO, Bloomberg News reported on Monday, citing people with knowledge of the matter.

Teck shares surged 20% in overnight trading.

The Financial Times separately reported on Monday the potential transaction could value Teck at about $20 billion.

The London-listed global miner is considering paying mostly in stock, with an announcement potentially expected as early as this week, the report said.

However, the timing and terms of the deal remain uncertain, and talks could still collapse without an agreement, the report added.

Teck Resources holds a market valuation of approximately C$23.69 billion (about $17.17 billion), while Anglo American is valued at around 26.82 billion pounds (roughly $36.35 billion), as per LSEG data.

Both Anglo American and Teck have drawn interest from larger rivals in recent years. Anglo fended off a $49 billion takeover proposal from BHP Group last year, while Teck rejected a full buyout offer from Glencore in 2023 for $22.5 billion.

Glencore, which later bought Teck's steelmaking coal business for $6.93 billion, has repeatedly said it remains interested in the Canadian miner, raising the prospect of a bidding battle if Anglo were to make an approach.

Reuters could not immediately verify the report. Teck, Anglo American and Glencore did not immediately respond to Reuters' requests for comment.
