AUMI vs SLVR

AUMIBThemes Gold Miners ETF

SLVRDSprott Silver Miners & Physical Silver ETF

In short

AUMI Gold miners with the blends stripped out. AUMI tracks an index of roughly 30 large miners that must earn at least 90% of revenue from gold, and it charges less than the typical fund in its group.

SLVR Most silver funds make you choose: the metal or the miners. SLVR holds both, tracking an index of silver-mining companies alongside physical-silver trusts, in a peer group where 'precious metals miners' usually means gold.

Stated mandate

AUMI The Fund seeks to track, before fees and expenses, an index of companies active in the gold mining industry. It uses a passive/indexing approach to pursue that objective.

SLVR The Fund seeks to track an index focused on silver-mining companies and physical-silver trusts. It normally invests at least 80% of total assets in securities of that index.

Why people hold it

• AUMI The "pure" in the index name is a rule: members must generate at least 90% of revenue from gold mining, so copper-and-gold conglomerates and diversified diggers stay out.solactive.comthemesetfs.com
• A 0.35% fee undercuts the peer-group median and the category's household names, VanEck's GDX (0.51%) and iShares' RING (0.39%).
• Roughly 30 names, free-float weighted, rebuilt on a set schedule: a concentrated, rules-based way to own the diggers rather than the metal.solactive.com

• SLVR One wrapper, both sides of the silver trade: the index blends silver miners with physical-silver trusts, and at least 80% of assets normally sit in it.
• Genuinely silver-first. Much of its cohort (RING, GDX, GDXJ) is built around gold miners, with silver as an afterthought.
• The portfolio hews closely to the index it promises, with little style drift, and spreads across roughly 80 miners and metal trusts.

Worth knowing

• AUMI Thinly traded and small next to the group's giants, so bid-ask spreads can be wider and big orders can push the price.
• Concentrated by design and non-diversified: about 30 miners, one commodity, plus mine-level risks like costs, permits and politics.themesetfs.com
• Launched in December 2023, so the live track record is short, and cash comes back once or twice a year rather than monthly.

• SLVR At 0.65% a year, it costs more than the typical fund in its group. AGMI (0.35%) and SLVP (0.39%) cover silver miners for less.
• One metal, one industry. Miner shares tend to amplify silver's swings in both directions, and this book is concentrated.
• Launched in 2025, so the track record is short. Volume is moderate rather than heavy, and cash comes back once or twice a year, not monthly.
