The All Ordinaries Index (ASX: XAO) has gained 5% so far in 2025, but this ASX All Ords silver share has left those gains wanting.
The fast-rising miner in question is Andean Silver Ltd (ASX: ASL).
In morning trade on Tuesday, Andean Silver shares are changing hands for $2.20 apiece, up 2.3%.
This sees the ASX All Ords silver share up 161.9% in 2025.
And investors who bought the stock two years ago (when the company was still called Mitre Mining) will be sitting on eye-watering gains of 746% today.
Andean Silver has been benefiting from both its own successes at its Cerro Bayo silver-gold project in southern Chile as well as the soaring gold and silver price.
The silver price has doubled since 1 January this year, currently trading for US$57.96 per ounce.
Now, here's what's grabbing ASX investor interest today.

ASX All Ords silver share lifts off on high-grade results
The Andean Silver share price is marching higher again today after the miner announced it has discovered more extensive vein systems with high-grade gold and silver mineralisation at Cerro Bayo epithermal silver-gold project.
The ASX All Ords silver share said the latest rock chip sampling results revealed more than two kilometres of exposed mineralised veins with grades of more than 10,000 grams of silver per tonne and 125g/t gold.
And there's a lot of promising area left to explore.
According to the release, a 750-metre corridor between the Taitao and Cristal prospects is still unmapped and untested by drilling.
And the silver miner noted that the corridor continues for 1.3 kilometres under shallow cover between the Droughtmaster and Guanaco mines, adding that geophysical anomalies indicate the potential for further prospective concealed and untested zones.
What did management say?
Commenting on the sample results boosting the ASX All Ords silver share today, Andean CEO Tim Laneyrie said, "These results again demonstrate that there is scope to grow the Cerro Bayo resources beyond current levels."
He said the upside "isn't just based on favourable geology or geophysics, it is underpinned by well-mineralised veins over extensive lengths with very high-grade silver and gold".
Looking ahead, Laneyrie added:
We have a long pipeline of these well-advanced prospects for exploration which have been identified by sampling and a thorough re-evaluation of the geological data at Cerro Bayo.
Our focus is on continuing to grow the resource, with a fleet of drill rigs on site, as we head into 2026. We will also ramp up drilling while advancing the mine study phase in the new year as part of a multi-pronged strategy to drive shareholder value.
