BSE Metal Sector Regulatory Filings — October 03, 2026

Record Q2 mined metal production of 271 kt (+5% YoY) and record H1 refined metal production of 524 kt (+6% YoY), indicating strong operational momentum and potential for earnings upgrades

Silver production surged 20% YoY to 173 tonnes in Q2, a high-margin by-product that directly boosts EBITDA margins and provides a natural hedge against base metal price volatility

Wind power generation rose 17% YoY to 155 million units, signaling successful cost-reduction initiatives in power and a lower carbon footprint, which may attract ESG-focused capital

Record first-half mined metal production of 539 KT (+3% YoY) and refined metal production of 524 KT (+6% YoY), mirroring HZL’s strength and confirming the domestic zinc cycle is robust

Silver production reached 173 tonnes in Q2 (+20% YoY), aligning with HZL’s silver growth and indicating a strong by-product revenue tailwind for the broader Vedanta group

Sales plunged 64% YoY to 16 KT due to the Strait of Hormuz closure, a severe operational disruption that will materially impact Q2 earnings and may trigger debt covenant concerns

Total mined metal declined 13% YoY to 102 KT, with BMM mined metal content collapsing 55% YoY to 10 KT, signaling depletion or operational issues at a key international asset

Ferrochrome production grew 26% YoY, a bright spot in the international portfolio that partially offsets weakness in other segments and points to strong stainless-steel demand

Record first-half cargo handling, indicating infrastructure assets are performing well and providing a stable, non-cyclical revenue stream within the conglomerate

Refined zinc production was nearly flat sequentially (-0.4% QoQ), suggesting a potential plateau in near-term output growth despite the strong YoY performance [NEUTRAL/BEARISH]

Copper International sales down 64% YoY due to Strait of Hormuz closure – this is a high-impact, unpredictable event with no clear resolution timeline, posing a material risk to Q2 and Q3 consolidated earnings

BMM (Zinc International) mined metal content declined 55% YoY to 10 KT in H1, indicating potential resource depletion or severe operational challenges that could lead to asset impairment

Zinc India now accounts for an even larger share of Vedanta’s profitability, making the conglomerate highly sensitive to any domestic zinc price correction or regulatory change

Refined zinc production was flat QoQ (-0.4%), suggesting that after record H1 output, the company may face capacity constraints or maintenance shutdowns in H2, limiting further upside

Total Zinc International mined metal down 13% YoY – this is the second consecutive period of decline, pointing to a structural issue rather than a one-off event

The Strait of Hormuz closure impacts not just copper but potentially other raw material or product flows for Vedanta’s international operations, creating a multi-segment risk

Gamsberg Phase 2 is commissioned but saleable production is only expected from October 2026 – any delay in ramp-up will exacerbate the Zinc International weakness

With record H1 production and strong silver growth, HZL is well-positioned to beat consensus estimates. Investors should look for Q2 earnings calls for margin commentary and potential guidance upgrades

Commissioned in Q2 FY27, with saleable production expected from October 2026. If ramp-up is smooth, this could reverse the Zinc International decline and provide a significant earnings catalyst in H2 FY27

Record first-half cargo handling provides a non-cyclical earnings buffer. As a standalone infrastructure asset, it may be undervalued within the conglomerate structure and could be a candidate for a future monetization or IPO

Ferrochrome production up 26% YoY, benefiting from strong stainless-steel demand. This segment could be a hidden gem if the trend continues, offering diversified exposure to the alloy market

With silver production growing 20% YoY and silver prices remaining elevated, HZL’s by-product revenue is becoming a material profit driver. Investors can gain leveraged exposure to silver through a base metal stock

If the Strait of Hormuz situation resolves in H2 FY27, Copper International sales could rebound sharply from a low base, creating a potential earnings swing trade

Wind power generation up 17% YoY signals a genuine commitment to renewable energy. As ESG mandates tighten, HZL may command a valuation premium over peers with higher carbon footprints

Both Hindustan Zinc and Vedanta’s Zinc India reported record production, indicating strong domestic demand for zinc driven by infrastructure and galvanizing demand. This is a sector-wide positive for Indian metal companies with domestic exposure.

Vedanta’s Zinc International (-13% YoY) and Copper International (-64% YoY) highlight the risks of global operations. The theme is a clear divergence: domestic assets are firing on all cylinders, while international assets face geopolitical and operational headwinds.

Both HZL and Vedanta Zinc India reported 20% YoY growth in silver production. This is a consistent theme across the zinc sector, where silver by-product revenue is becoming a critical margin driver and a differentiator for valuation.

The Strait of Hormuz closure impacting Vedanta’s copper sales is a reminder that metal companies with supply chains passing through conflict zones face sudden, severe earnings shocks. Investors should scrutinize supply chain exposure in other index constituents.

HZL’s 17% YoY increase in wind power generation and record production levels suggest that cost optimization and capacity utilization are key themes. Companies that can improve operational efficiency are outperforming those reliant on volume growth alone.

Watch for management commentary on H2 production guidance, silver price hedging, and any plans for dividend increases given record cash flow. Date: typically within 45 days of quarter end (mid-November 2026)

Monitor monthly production disclosures from October 2026 onwards. A smooth ramp-up could be a major positive catalyst for Vedanta’s stock, while delays would exacerbate Zinc International weakness.

Any news of the Strait of Hormuz reopening would be a strong positive catalyst for Copper International. Monitor geopolitical developments in the Middle East.

Watch for Q3 FY27 production data to see if sales stabilize or recover from the 64% YoY plunge. A sequential improvement would signal a bottom.

With Q2 refined zinc flat QoQ, watch Q3 production data for any signs of a decline or a rebound. This will indicate whether the record H1 was a peak or a new baseline.

Monitor any announcements regarding the BMM mine (Zinc International). A further decline in mined metal content could lead to an impairment charge, which would be a significant negative event.
