Capital Markets presentation

A unique opportunity to support the electric revolution

Hochschild Mining PLC ("Hochschild" or "the Company") (LSE: HOC) (OTCQX: HCHDF) is to hold a remote Capital Markets event presentation for analysts and investors at 14:30 today (UK time) on its rare earths project. A replay of the presentation will be published on the Hochschild website at http://www.hochschildmining.com/en/home following the event.

Key highlights of the presentation:

§ A unique, high value, sustainable Ionic Clay rare earth project in Chile

§ Offers critical supply of higher value heavy rare earths outside China

§ Ideally placed to meet exponential rare earth demand underpinning the electric revolution

§ Simple strategy of starting with a minimum viable product, then targeting optimization, growth and integration

§ A multi-module growth strategy with module one delivering high returns:

o NPV of approximately $152-177 million

o Life-of-mine: 11 years

o Low project capital expenditure of approximately $119 million

o Average annual EBITDA of approximately $50m[1]

§ Name changed to Aclara (formerly known as Biolantanidos)

Ignacio Bustamante, Chief Executive Officer said:

"We acquired 100% of Aclara in October 2019 and have applied Hochschild's operational expertise and distinctive culture to move the project forward. In taking on the project, we have dealt with new minerals and a value chain dynamic that is totally different from precious metals and relatively unknown to the western world. It is a challenge we have embraced and one which has enriched our organization still further. I am confident that the combination of our de-risking process together with strong fundamentals underlying our investment thesis and the significant recent increase in rare earth prices will deliver a very exciting future for this business."
