May 1 (Reuters) - Canadian miner Barrick Gold beat Wall Street estimates for first-quarter profit on Wednesday, on the back of a rally in bullion prices during the quarter.

On an adjusted basis, the world's second-largest gold miner posted a profit of 19 cents per share in the January-March quarter, compared with analysts' expectations of 15 cents, according to LSEG data. (Reporting by Vallari Srivastava in Bengaluru; Editing by Krishna Chandra Eluri)
