Metro Mining's Low-Cost Bauxite Edge Survives Repeated Setbacks

Production hiccups and softer shipments have tested patient holders, but Metro Mining's position as the lowest-cost global bauxite producer keeps the structural thesis intact.

Metro Mining, a unique small-cap bauxite producer with structural exposure to the growing aluminium market, roughly doubled to record highs on a strengthening balance sheet and growing free cash flow, before production hiccups and softer than expected shipments triggered repeated sell-offs that have tested even patient long-term holders.

A structurally attractive, low-cost bauxite exposure

Firetrail Investments said Metro Mining rose reflecting broader strength in the resources sector, describing a unique small company with exposure to a structurally growing market in aluminium, low-cost relative to peers, a long mine life that can be expanded, and highly free cash flow generative, anticipating the September quarter result would show strong free cash flow. Monash Investors said Metro Mining continued its strong run, up 25 percent, part of a broader re-rating across its small resources positions.

Metro Mining is a unique small company in that it has exposure to a structurally growth market (aluminium), is low-cost relative to peers, has a long mine life (which can be expanded) and is highly free cash flow generative.

Production hiccups trigger repeated sell-offs

DMX Asset Management said Metro Mining cost the fund nearly 1 percent as shares fell 23 percent, having performed strongly over the past year, roughly doubling to recent highs on a strengthening balance sheet as it started generating significant free cash flow from its North Queensland bauxite mining operation, before recent production hiccups and reduced expectations for volumes and net margins weighed on the shares. Perennial Partners said Metro Mining reported softer than expected cash flow during the quarter, selling off 23.2 percent, though the fund had fortunately halved its position size prior to the quarterly report.

Recent production hiccups and reduced expectations for volumes and net margins moving forward weighed on shares.

Operational momentum returns

Perennial Partners said Metro Mining rose 17.9 percent, contributing positively as the fund built a small position, with the share price supported by improving operational momentum at the Bauxite Hills Mine and a stronger outlook for shipments through the second half, reporting May shipments of 604,000 tonnes, up 45 percent on the prior month, following the return of the Offshore Floating Terminal Ikamba.

China's iron ore moment in bauxite

Katana Asset Management confessed the stock is testing the fund's patience, having had a good number of operational mishaps, but believes China is having its iron ore moment in bauxite, describing Metro Mining as the lowest-cost producer of bauxite globally, able to land bauxite in China at around US$30 a tonne.

I must confess it is testing our patience. They've had a good number of operational mishaps, so we are being tested here, but we believe that China's having its iron ore moment in bauxite. Metro Mining is the lowest-cost producer of bauxite globally.

What fund managers say they are watching next is whether the Offshore Floating Terminal Ikamba and Bauxite Hills Mine continue delivering stable operations without further hiccups, continued growth in shipment volumes toward the stronger second-half outlook, delivery of the free cash flow generation the low-cost structure should support, and whether China's structural bauxite demand thesis continues playing out.
